4-series lithium battery protection board 30A high current
Descriptions
1. 4-series 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, the protection is automatically canceled after the protection conditions are restored, and no charger activation is required, which is more convenient to use.
Module parameters:
1. Module name: 4-series lithium battery protection board
2. Module properties: polymer lithium battery protection board
3. Overcharge detection voltage: 4.25±0.025V
4. Overcharge release voltage: 4.15±0.05V
5. Over discharge detection voltage: 2.50±0.08V
6. Over discharge release voltage: 3.00±0.1V
7. Overcurrent: 20-30A
8. Working current: 15A (natural heat dissipation 10A, with heat sink 15A, maximum instantaneous current 30A)
9. Release condition: Automatic recovery after the protection condition is released, no activation required (charger activation is optional)
Main functions: overcharge protection, over-discharge protection, short circuit protection, over-current protection.
10. Working temperature: -40~+85 degrees (please strengthen heat dissipation when the ambient temperature is too high)
11. Wiring method: welding output
12. Module size: 50mm *22mm*4mm
13. Module weight: grams
Applications:
1. This protection board can be used as overcharge, overdischarge, short circuit protection for four-string polymer lithium battery packs with nominal voltage of 14.4V, 14.8V, 16.8V, four-string 18650 lithium battery packs, etc. It does not need to activate the function in power applications with high instantaneous current, and can avoid false triggering protection in inverter applications, making it more convenient to use.
