4S Li-ion Battery Charger Protection Board 14.4V, 14.8V and 16.8V 15-30A– Overcharge/Discharge/Short Circuit Protection for Lithium Battery Packs

Product Description

4 Series High Current Lithium Battery Charger Protection Board safeguards your 14.4V, 14.8V, and 16.8V lithium battery packs. This protection board avoids damage during charging and discharging cycles, extending overall battery lifespan. Ideal for high-demand applications, it supports dynamic use with high instantaneous currentInstall the protection board by welding connections to your battery pack. It automatically activates upon connection. During use, the board continuously monitors voltage and current. If overcharge, overdischarge, overcurrent, or short circuit conditions occur, protection engages instantly. When parameters return to normal, the system automatically resumes run without requiring charger reactivationSpecifications:Overcharge Test Voltage: 4.25±0.025VOvercharge Relieve Voltage: 4.15±0.05VOver Discharge Test Voltage: 2.50±0.08VOver Discharge Relieve Voltage: 3.00±0.1VOver Current: 20~30ARunning Current: 15A(passive heat dissipation 10A, with heat sink 15A, high instantaneous current 30A)Termination Conditions: Elimination of protection condition automatic recovery, without activation(optional charger activation)Function: Overcharge protection, over discharge protection, short circuit protection, over-current protection.Working Temperature: -40 to +85 degrees(ambient temperature too high, please strengthen cooling)Module Size: 50 * 22 * 4mm(1.97 * 0.87 * 0.16in)Module Color: RedInstallation Method: WeldingWeight: 6g(approx.)Package Includes:1 xProtection BoardNote:1.
