1. Interchange with lead acid battery 2. Lightweight but powerful 3. Easy to use 4. LED indicator for show battery status
Specification
This specification is applied to the LiFePO4 battery pack that manufactured by O’CELL Technology Co., Ltd. There is built-in smart PCM for over charge/discharge, over temperature and short-circuit protection. It owns RS485 interface for communication with host. It has a LED status indicator and balancing function during charging.
It can connect in series up to 48V battery system. Extra BCK (Battery Controlling Kit) is recommended to monitor the whole battery system and aid battery system balancing.
