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 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. Battery compatibility: Voltage of 3.2V - 3.65V LiFePO4 battery (18650, 26650, Prismatic) Battery voltage range: 12v - 14.4v Maximum balance current: 66mA Board Size: approx. 20.1*25.8*2.4mm Package includes: 1 x 4S LiFePO4 Battery Balance Board Wiring Instructions: B- is connected to the negative terminal of the battery 1(-) B1 connects between battery 1(+) and battery 2(-) B2 connects between battery 2(+) and battery 3(-) B3 connects between battery 3(+) and battery 4(-) B4 is connected to the positive terminal of battery 4(+) Shipping Note: Single boards may be shipped via USPS First Class Large Letter locally from the Cleveland area, a tracking number may not be available. Orders of two (2) or more will be shipped as a First Class Package including a tracking number.
