This article covers common Fusion battery charging questions, troubleshooting tips and best practices to help you get the most from your battery and charger.<h2 style="text-align: center;" id="charger-troubleshooting">Charger Troubleshooting</h2><h2 id="isPasted">Charger isn&apos;t charging the battery</h2>The Fusion charger is a smart charger that communicates with the battery&apos;s Battery Management System (BMS) before charging begins. This &quot;handshake&quot; is a normal safety feature.Occasionally, if charging is interrupted (for example, the charger is unplugged while charging), the charger may not immediately restart when plugged back in.<h3 id="symptoms">Symptoms</h3><ul data-spread="false"><li style="font-size: 14px;">Charger remains solid green.</li><li style="font-size: 14px;">Battery does not begin charging.</li><li style="font-size: 14px;">Fan does not start.</li><li style="font-size: 14px;">Charger appears to have finished charging when it hasn&apos;t.</li></ul><h3 id="isPasted">Solution</h3><ol data-spread="false" start="1"><li style="font-size: 14px;">Disconnect the charger from power.</li><li style="font-size: 14px;">Wait 10&#x2013;15 seconds&#xA0;until:<ul data-spread="false" style="font-size: initial;"><li style="font-size: 14px;">the charger light turns completely off</li><li style="font-size: 14px;">you hear the internal relay click.</li></ul></li><li style="font-size: 14px;">Reconnect the charger to power.</li><li style="font-size: 14px;">Allow the charger and battery a few seconds to complete their handshake.</li><li style="font-size: 14px;">Charging should begin normally.</li></ol>When charging starts correctly you will notice:<ul data-spread="false"><li style="font-size: 14px;">the charging indicator begins flashing</li><li style="font-size: 14px;">the charger fan starts running.</li></ul>Tip:&#xA0;Around 99% of charging issues are resolved by fully power cycling the charger before reconnecting it.<h2 id="isPasted" style="text-align: left;">Charger flashing red and green</h2>A flashing red and green indicator typically means charging was interrupted unexpectedly, such as unplugging the charger while it was actively charging.This is simply a charger status indication and is easily resolved.<h3 id="to-reset">To reset:</h3><ol data-spread="false" start="1"><li style="font-size: 14px;">Unplug the charger.</li><li style="font-size: 14px;">Wait until all lights have turned off.</li><li style="font-size: 14px;">Plug the charger back in.</li></ol>The charger will reconnect to the battery and resume charging normally.<h1 id="isPasted" style="text-align: center;">Charging to Full vs Storage Charge</h1>Fusion batteries support both:<ul data-spread="false"><li style="font-size: 14px;">Full Charge</li><li style="font-size: 14px;">Storage Charge</li></ul>If you select Storage Charge on the charger when the battery is already above the storage charge level (60%), the charger will stop immediately. This is normal behaviour.<h1 id="isPasted" style="text-align: center;">Why Won&apos;t My Battery Top Up the Last 1&#x2013;2%?</h1>Fusion batteries use intelligent charging logic.If your battery is already very close to full, the charger may determine that the charging cycle has already been completed and may not restart for the final 1&#x2013;2%.This is completely normal.Once the battery reaches approximately 50V, it is effectively fully charged. Although the battery can reach around 50.4V, the additional runtime gained is only a matter of seconds and is not worth repeatedly attempting to achieve.If you&apos;re unsure whether charging has completed:<ol data-spread="false" start="1"><li style="font-size: 14px;">Unplug the charger.</li><li style="font-size: 14px;">Wait for it to power down.</li><li style="font-size: 14px;">Plug it back in.</li></ol>If charging resumes, the battery will top itself up. If not, the battery is already considered fully charged.<h1 id="isPasted" style="text-align: center;">Charging Without the Battery Caddy</h1>The Fusion battery can be charged either:<ul data-spread="false"><li style="font-size: 14px;">through the Battery Caddy</li><li style="font-size: 14px;">or by connecting the charger directly to the battery.</li></ul>Both methods function exactly the same.<h1 id="isPasted" style="text-align: center;">Storage Charging After Riding</h1>If you&apos;ve ridden your battery down to a very low state of charge (single-digit percentage), it is important to recharge it to Storage Charge within a few days.Fusion batteries contain an active BMS and Bluetooth system which consume a very small amount of power, even while the battery is stored.Leaving a battery at a very low state of charge for an extended period can result in over-discharge.<h3 id="best-practice">Best practice</h3>After your session:<ul data-spread="false"><li style="font-size: 14px;">place the battery on Storage Charge</li><li style="font-size: 14px;">allow it to reach storage level</li><li style="font-size: 14px;">store it until your next ride.</li></ul>This keeps the battery healthy and means your next full charge is quicker.<h1 id="isPasted" style="text-align: center;">Long-Term Storage (Winter Storage)</h1>If your battery will not be used for several months:<ul data-spread="false"><li style="font-size: 14px;">charge it to Storage Charge</li><li style="font-size: 14px;">store it in a cool, dry location.</li></ul>Important:&#xA0;Do not store a battery that has been discharged below approximately 10% for long periods.&#xA0;Doing so may allow the battery to self-discharge below its safe operating voltage.A battery stored correctly at Storage Charge can typically remain healthy for many months.&#xA0;

<div data-block="true" data-editor="6bnr0" data-offset-key="6fs8r-0-0" id="isPasted">If you have a 43V Foil Drive Battery, you may notice that both the Battery Caddy and the Foil Drive App display 100% State of Charge while the battery remains connected to the charger and is still actively charging.This is completely normal and is part of how lithium battery charging and the Battery Management System (BMS) work.<h2 id="isPasted" style="text-align: center;">Why does this happen?</h2>The Battery Management System (BMS) continuously estimates the battery&apos;s State of Charge using several factors, including:<ul data-spread="false"><li style="font-size: 14px;">Battery voltage</li><li style="font-size: 14px;">Current flow</li><li style="font-size: 14px;">Battery behaviour during charging and discharging</li></ul>As the battery approaches full charge, the charging process slows significantly to protect the battery and maximise its lifespan.Although the app may display 100%, the charger may still be:<ul data-spread="false"><li style="font-size: 14px;">Balancing the individual battery cells</li><li style="font-size: 14px;">Gently topping up the final portion of the battery&apos;s capacity</li></ul>This ensures every cell reaches the correct voltage before charging is complete.<h2 id="isPasted" style="text-align: center;">A simple analogy</h2>Think of charging your battery like filling a car with fuel.Most of the fuel goes in quickly, but as the tank nears full, the fuel pump automatically clicking off when the tank is essentially full.If you&apos;ve ever gently squeezed the nozzle after the first click, you&apos;ll know you can often add a small amount more before the tank is completely full.Lithium batteries behave in a similar way.The Foil Drive App and Battery Caddy display 100% once the battery is effectively full for normal use, while the charger continues the final balancing and top-up process in the background.</div><h2 id="isPasted" style="text-align: center;">Why doesn&apos;t the percentage keep increasing?</h2>The battery percentage is an estimate of usable charge rather than a direct measurement of every individual cell.Once the battery reaches its usable full capacity, the displayed State of Charge remains at 100%, even though the charger may still be performing the final balancing process.This is expected behaviour and does not indicate a fault with the battery, charger or Battery Caddy.<h2 id="isPasted" style="text-align: center;">A closer look at your battery</h2>Unlike many battery-powered products that only display a simple percentage, the Foil Drive App provides detailed battery information, including:<ul data-spread="false"><li style="font-size: 14px;">State of Charge (%)</li><li style="font-size: 14px;">Total battery voltage</li><li style="font-size: 14px;">Individual cell voltages</li><li style="font-size: 14px;">Remaining amp-hours (Ah)</li><li style="font-size: 14px;">Charging status</li><li style="font-size: 14px;">Cell balancing information</li></ul>This provides a real &quot;look under the hood&quot; of what the battery is doing internally. Rather than simply showing Full or Empty, the app allows you to monitor the health and behaviour of the individual cells that make up the battery pack.<h2 id="isPasted" style="text-align: center;">Is this normal?</h2>Yes.If your 43V battery shows 100% while it remains connected to the charger, this simply means the battery has reached its usable full capacity and the charger is completing the final balancing and top-up process.&#xA0;You can remove the battery from the charger once it reaches 100% charge, but if you&apos;re not in a rush, leave it connected to the charger to finish the final balance charge.&#xA0;

Why Does My 43V Battery Show 100% While It's Still Charging?

If you want to charge your FD battery from a car or mobile platform, here are some things to consider. If you're charging from a normal Lead Acid or AGM car battery, a single Standard Assist PLUS 12.6 Ah battery can drain a car battery by at least 50

If you want to charge your FD battery from a car or mobile platform, here are some things to consider. If you&apos;re charging from a normal Lead Acid or AGM car battery, a single Standard Assist PLUS 12.6 Ah battery can drain a car battery by at least 50% in just one charge - so you don&apos;t want to make your car go flat. It&apos;s best to have a 2nd battery installed in your car to avoid this. &#xA0;If you&apos;re looking for a 2nd battery, a deep discharge battery is preferred over a normal car battery as they are designed for cold cranking amps as opposed to sustained amp draw. &#xA0;You cannot charge a battery from your normal 12V car cigarette lighter. Most cars 12V &#xA0;cigarette lighter plugs can&apos;t handle more than 100 watts sustained and your FD+ charger will draw about 160 watts sustained.&#xA0;Really cheap, clipped sine wave inverters are not recommended as they have very poor power delivery and can damage electronics.Assist PLUS batteries: Minimum 300W/12-24V inverter&#xA0;Gen2 Standard and Fast Chargers:&#xA0;&#xA0;Minimum 500W/40V inverter <div data-block="true" data-editor="dejjp" data-offset-key="7gmq-0-0"><div data-offset-key="7gmq-0-0">RedArc are a good brand, and is important to purchase a Pure Sinewave, of a reputable brand, and not a knock off Alibaba or similar.&#xA0;</div> </div>Recommended products:<span id="isPasted" style="color: rgb(8, 188, 193); font-family: Inter, &quot;Helvetica Neue&quot;, Arial, Helvetica, sans-serif; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(249, 249, 249); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; float: none; display: inline !important;">This one would charge 2 x max power&#xA0;<span id="isPasted" style="color: rgb(34, 34, 34); font-family: Inter, &quot;Helvetica Neue&quot;, Arial, Helvetica, sans-serif; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(249, 249, 249); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; float: none; display: inline !important;">&#xA0;&#xA0;<a href="https://www.bluettipower.com.au/products/bluetti-ac180-portable-power-station" rel="noreferrer noopener" style="box-sizing: border-box; -webkit-font-smoothing: antialiased; background-color: rgb(249, 249, 249); color: var(--main-primary); text-decoration: none !important; font-family: Inter, &quot;Helvetica Neue&quot;, Arial, Helvetica, sans-serif; font-size: 14.6667px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal;" target="_blank">https://www.bluettipower.com.au/products/bluetti-ac180-portable-power-station</a>&#xA0;<span id="isPasted" style="color: rgb(8, 188, 193); font-family: Inter, &quot;Helvetica Neue&quot;, Arial, Helvetica, sans-serif; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(249, 249, 249); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; float: none; display: inline !important;">This one will do 4 x max powers<span id="isPasted" style="color: rgb(34, 34, 34); font-family: Inter, &quot;Helvetica Neue&quot;, Arial, Helvetica, sans-serif; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(249, 249, 249); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; float: none; display: inline !important;">&#xA0;&#xA0;<a href="https://www.bluettipower.com.au/products/ac200l-portable-power-station" rel="noreferrer noopener" style="box-sizing: border-box; -webkit-font-smoothing: antialiased; background-color: rgb(249, 249, 249); color: var(--main-primary); text-decoration: none !important; font-family: Inter, &quot;Helvetica Neue&quot;, Arial, Helvetica, sans-serif; font-size: 14.6667px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal;" target="_blank">https://www.bluettipower.com.au/products/ac200l-portable-power-station</a>Remember cars can get VERY hot inside when closed up and we do not recommend charging batteries inside a closed up vehicle as the charger or battery could get too hot. &#xA0;Always make sure the chargers have ventilation when being used.&#xA0;
