4-string lithium battery protection board 30A high current
Parameter:
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: 3.00±0.1V
Overcurrent: 20-30A
Operating current: 15A (natural heat dissipation 10A, heat sink 15A, maximum instantaneous current 30A)
Release condition: The protection condition is released and automatic recovery is not needed (optional charger activation, please refer to the operating instructions)
Main functions: Overcharge protection, overdischarge protection, short circuit protection, and overcurrent protection.
Operating temperature: -40+85 degrees (add heat when the ambient temperature is too high)
Wiring method: welding output
Module size: 50mm*22mm*4mm
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.
1. Automatic activation description: When the 0 ohm resistance is affixed to the circle as shown above, the automatic activation function is enabled. When the application condition exceeds the protection parameter, the protection board starts protection. When it is restored to the protection parameter, it automatically returns to the normal output. Manual activation or charge activation
2. Non-automatic activation Description: If the 0 ohm resistor is not attached to the circle, the auto-activation function is turned off. If the application condition exceeds the protection parameter, the protection board starts protection. When the protection parameter is restored, it will not resume normal output. , need manual activation or charge activation.
