12V 20Ah Lithium Battery Connectors
Important:
- When purchasing an Elemex battery, always ensure that voltages are paired correctly eg. a 12V motor must be paired with a 12v battery. Any controllers that are burnt out due to reprogramming or incompatible pairing are not covered by warranty.
- Often riders would like to go for a High-Capacity battery however their bike frame doesn’t have enough space in the inner diamond to fit one, this is particularly true for dual suspension bikes. If under-mounting or rear mounting the battery is not an option, then they may have to purchase 2x smaller capacity batteries and for long rides keep one in a backpack and swap them out.
- Please check the dimensions of this 12V 20Ah Scooter eBike Battery before placing your order.
- If you are unsure of which battery to pair with your bike, please do not hesitate to contact us for more information.
