Lithium Battery Charger Protection Module (BMS) 5S 100A 21V

Description

Features: This protection board is in common use lithium battery protection board (you can adjust for how many strings to be used) Specified chip, stable performance, support disconnection protection, over-current protection, over-discharge protection, overcharge protection, with balance, etc. A common use for “same port” and “different port”, the protection board uses 15 high-power of ultra-low resistance MOS tubes (discharge of 8, charging of 7), in the same port mode can support the discharge current 60A, charging current 60A; different port mode discharges current 80A, charging current 60A. Can used for (3.7V) battery packs etc. Specifications: Single-cell battery overcharge protect voltage: 4.21-4.29 V Single-cell battery overcharge protects recover voltage: 4.14-4.24 V Overcharge protect delay : 1.5-2.5S Single cell battery over-discharge protect voltage : 2.72-2.88 V Single cell battery over-discharge protect recover voltage : 2.9-3.1 V Over charge protective current:100A Over discharge protective current:100A Over-discharge protect delay : 0.5-1.5S Temperature protects: Yes, have a Temperature control interface. Disconnect protect: Yes Shortage protection: Yes Shortage delay: 100-600 uS Shortage protects recover mode: Offload release. balance function: yes Ampere balance (Current): 60MA Current balance accuracy: 4.14-4.24V Material: PCB Size:60x42x4mm
