Balanced Charging: Maintains uniform voltage across all cells for improved performance and extended battery life.
High Discharge Capability: Supports up to 5A continuous discharge, ideal for high-power applications.
Compact and Round Design: Easy to fit in space-constrained applications.
Nominal Voltage: 7.4V
Maximum Continuous Discharge Current: 5A
Battery Type: 2S (2 Series) Li-ion or Li-Po battery packs
Protection Features: Overcharge, Over-discharge, Short-circuit, Balanced Charging
Balancing Current: Up to 60mA per cell
Operating Temperature Range: -20°C to +60°C
Connect the negative terminal of the first battery to the B- pad (0V) and the positive terminal to the B1 pad (4.2V).
Connect the negative terminal of the second battery to the B1 pad (4.2V) and the positive terminal to the B+ pad (8.4V).
Use the P+ and P- pads for both charging and load connections.
Always connect in the specified order to prevent damage to the BMS.
Use a buck voltage module to adjust charging voltage and current to match the battery specifications before charging.
Note: This module provides protection functions only. Charging must be managed by an external charger or buck converter module.
