Clear answers to the questions customers usually ask before booking a free home demo.
Can I use my existing AGM charger with this battery?
No. This is a LiFePO4 lithium battery and must only be used with a lithium-compatible charger. Charging it with a standard AGM or lead-acid charger is a genuine safety risk and should never be done. Check your charger's specification, or speak to your supplier, before charging this battery.
What does the Battery Management System (BMS) do?
The built-in BMS protects the battery against overcharge, over-discharge and short circuit, supporting safer everyday use when paired with the correct lithium charger.
Why might I choose lithium over AGM or gel?
Lithium batteries are around 70% lighter than an equivalent AGM battery and offer a significantly longer cycle life, making them a popular upgrade for anyone who travels frequently with their scooter or powerchair, or who finds lifting a standard AGM battery difficult.
Do I need to buy two of these?
Most mobility scooters and powerchairs run on a 24V system, which typically needs two 12V batteries wired in series. It's worth checking your device's existing battery setup or manual to confirm how many you need, and to confirm your device is compatible with a lithium upgrade.
Is VAT relief available on this battery?
No, mobility batteries are charged at the standard 20% VAT rate and are not eligible for VAT relief, regardless of disability or long-term illness status.
