Example Uses:

1. This balance module can be used in parallel with a BMS to boost the balance efficiency of battery/BMS setup.

2. Secondly, the balance module can be used without a BMS, and will keep the individual battery cells within healthy balance levels.

3. Lastly, this balance module can be used in place of a traditional BMS. In specific setups where a battery is connected stable voltage source such as a 14v-14.6v charger or solar charge controller (14v-14.6v) and the output is controlled by a low voltage cutoff such as a inverter. 

Description:

This high power balance board can discharge up to 1.5A per hour and is a good fit for large capacity battery packs or batteries used in high drain applications where the cells are often cycled. This high power board may get HOT under load, it is advised to use caution when in use and the status LEDs are lit. 

This standalone balance equalization board is used for a 4S LiFePO4 battery pack without a balance feature. This standalone module does not charge or act as a low voltage/over charge cutoff. This board uses a resistor to balance each cell to 3.6v/3.65v. This board can also be added to an existing BMS battery setup to boost the effectiveness of the balancing function by increasing maximum balancing capacity. This balance board is for LiFePO4, LiFe, or LFP batteries. Lithium-ion (Li-ion)/Lithium-polymer (LiPo) based balance boards are in my other listings.
