4S 30A 12v 32650/32700 Lithium Iron Phosphet Battery Balance BMS Board Circuit

4 Series 30A 32650/32700 Lithium Iron Phosphet Battery Protection Board. Its 12.8V with Cable, a Balance Board for Drill Motor, Inverter, DIY projects Cell Module comes with recovery function-AUTO Recovery and Integrated 10 low load resistance MOS tube.

It provides continuous discharge of 30A, Balanced current, for electric drill/sprayer/LED lights/low power inverter.(if the cooling environment is not good, please reduce the load current use)

The Scope of Nominal voltage of 3.2V lithium battery (including 32700, 32650 lithium Iron Phosphate battery) where Charging voltage can be range between 14V to 15V. The board operates smoothly with Continuous charge current of (upper limit): 20A. The balanced version is suitable for starting current below 80A.

The Board comes in a size of approx. 46 x 60 x 3.4 mm which can be easily installed in a compact size or on battery bundle itself.

  1. The Successful start of Inverter, 15C-20C power battery, or six 10C-15C power battery (ordinary 32650,32700 cannot start), Use original Cells Like FB IFR, HX Etc.

  2. Strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, 16.8V, do not deliberately short circuit.

  3. When the load of the brush motor is used, try to connect a non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) to the motors positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube.

  4. 4 groups of batteries in series, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use in series. The Discharge test, the voltage drop faster battery that group is a poor battery.
