4 szál lítium akkumulátor védőkártya 30A nagy áramerősség 4 húr aktiválás nélkül, automatikus helyreállítás 14.8V 16.8V
4 strings of lithium battery protection board 30A high current 4 strings without activation, automatic recovery 14.8V 16.8V
4 series lithium battery protection boards, 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 cancelled after the protection condition is restored, without the need for charger activation, which is more convenient to use.
Module parameters:
Module name: 4-string lithium battery protection board
Module nature: polymer lithium battery protection board
Overcharge detection voltage: 4.25±0.025V
Overcharge release voltage: 4.15±0.05V
Overdischarge detection voltage: 2.50±0.08V
Over-discharge release voltage: 3.00±0.1V
Overcurrent current: 20-30A
Working current: 15A (natural heat dissipation 10A, plus heat sink 15A, maximum instantaneous current 30A)
Release conditions: the protection conditions are released and automatically restored without activation (optional charger activation)
Main functions: overcharge protection, overdischarge protection, short circuit protection, overcurrent protection.
Working temperature: -40~ 85 degrees (please strengthen heat dissipation when the ambient temperature is too high)
Wiring mode: welding output
Module size: 50mm*22mm*4mm
Application range:
This protection board can be used as a nominal voltage of 14.4V, 14.8V, 16.8V four-string polymer lithium battery pack, four-string 18650 lithium battery pack, etc. for overcharge, overdischarge, short circuit protection, etc. The function without activation is used in power applications with high instantaneous currents. In inverter applications, false triggering protection can be avoided, making it more convenient to use.
