⚠️ Cause of Battery Expansion (Swelling)

The battery swelled due to overcharging and overdischarging, which occurred because the inverter was using incorrect user-defined settings and had no communication with the battery’s BMS. Without proper voltage control, the system allowed:

Charging above the max limit (53.5V)

Discharging below the safe limit (46V)

This caused internal chemical damage, leading to gas buildup and swelling of the lithium cells.

✅ Recommendations to Prevent Future Damage

1. Use Inverters and Batteries with Communication Protocols (RS485/CAN):

Ensures real-time data exchange between inverter and BMS for safe charging/discharging.

2. Avoid Deep Discharges:

Never discharge below 20% State of Charge (SoC). Staying above 46V protects battery lifespan and safety.

3. Manually Configure Inverter Carefully (if no communication):

Max Charge Voltage: 53.5V

Low Voltage Cutoff: 46V

Float Voltage: 52V or disabled

Max Charge Current: ≤ 0.5C (e.g., 50A for 100Ah battery)

4. Add a Battery Monitor:

Tools like a Victron SmartShunt or JBD display help track real SoC and voltage.

5. Protect with Breakers or Relays:

Use automatic cutoff if voltage goes outside safe range.
