Enerkey 7S 120A All Lithium Smart BMS With Balancing Function Perfect for Solar Inverters & Medical Devices
7S120A Lithium Battery Protection Board Product Introduction
Basic Parameters
Battery Configuration
Applicable to 7-series ternary lithium battery pack (nominal voltage 11.1V, full charge voltage 12.6V).
Support single-cell voltage range: 3.0V~4.25V (overcharge/over-discharge protection threshold adjustable).
Current Performance
Continuous Discharge Current: 120A (typical value), supports short-term peak current 200~300A (overcurrent protection trigger).
Charging Current: Support 125A (typical value).
Protection Function
Overcharge Protection: Triggered when single-cell voltage ≥4.25V, recovery voltage 4.15V.
Over-discharge Protection: Triggered when single-cell voltage ≤2.75V, recovery voltage 3.00V.
Overcurrent/short circuit protection: Triggered when discharge current ≥250A, automatically recovers after 300~800ms delay.
Temperature protection: Some models support high and low temperature monitoring (need to be customized).
