Elemex eBike 52V 20Ah Lithium-ion Battery Pack + Charger

Important Notes:

• Ensure that voltages are paired correctly. For example, a 52V motor must be paired with a 52V battery. Controllers burnt out due to reprogramming or incompatible pairing are not covered by the warranty.
• Often riders may want a high-capacity battery, but their bike frame may not 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, consider purchasing two smaller capacity batteries and swapping them over during long rides.
• Check the dimensions of this item before placing your order.
• If unsure which battery to pair with your bike, contact us for more information.
• The appearance of the “Battery Level Light” may be slightly different from the photos. The listing photos are for illustration purposes only.
