Product Description
Power your high-performance e-bike build with this 72V 30Ah lithium-ion triangle battery pack, built with 21700 lithium-ion cells for big range and strong sustained power.

Battery Care & Charging
Store the battery in a clean, dry, ventilated, dark environment. If unused for an extended period, store it at 60–90% charge and top it up at least once a month. Avoid running the battery empty, and don't store it at 0% for long periods, as this can permanently damage the cells.
During charging, the charger's indicator light shows red; once fully charged, it turns green.
