Newly made, 4-string lithium battery protection board, suitable for nominal voltage 14.4V lithium battery pack, 14.8V lithium battery pack, 16.8V lithium battery pack. With automatic activation function, protection is automatically cancelled after protection conditions are restored, no charger activation is required, and usage is more convenient.

          Module Name: 4-string lithium battery protection board  

    Module properties: polymer lithium battery protection board

  Overcharge detection voltage: 4.25±0.025V

  Overcharge release voltage: 4.15±0.05V



   Over-discharge detection voltage: 2.50±0.08V


  Over discharge release voltage: 3.0 0±0.1V

   Overcurrent: 20-30A

   Operating current: 15A (natural heat dissipation 10A, plus heat sink 15A,maximum instantaneous current 30A ) For other currents, please contact customer service.


   Releasing condition: The protection condition will be automatically restored without activation (optional charger activation, please refer to operating instructions)

    Main functions: Overcharge protection, overdischarge protection, short circuit protection, and overcurrent protection.



    Operating temperature:-40~+85 degrees (enhance heat dissipation if the ambient temperature is too high)

    Wiring method: welding output

    Module size: 50 mm*22mm*4mm

   Module weight : grams



Application range:

The protection board can be used as a nominal voltage of 14.4V, 14.8V, 16.8V four-string polymer lithium battery packs, four string 18650 lithium battery packs as overcharge, overdischarge, short circuit protection. No activation function is required for power applications with very high instantaneous currents. Inversion applications can avoid false triggering and are easier to use.

The chip, the United States imported 70A large current low resistance MOS tube, heat is smaller. Large pad output, more secure wiring.

No part on the back design, can be attached to the heat sink, high current
