Can EG4 batteries be connected in series?

EG4 batteries can be connected in series if explicitly supported by the manufacturer’s specifications. Series connections increase total voltage while maintaining capacity, but require strict adherence to voltage limits, cell balancing, and BMS compatibility. Always verify the battery’s maximum allowable series count and use identical units to prevent imbalances. For example, two 48V EG4 batteries in series yield 96V, suitable for high-voltage solar storage systems. Pro Tip: Avoid mixing old and new batteries in series—capacity mismatches accelerate degradation.

What are the risks of improper series connections?

Improper series connections risk voltage imbalance and thermal runaway. If one cell in a series chain degrades faster, it creates unequal voltage distribution, forcing healthier cells to overcompensate. This can trigger overheating or BMS shutdowns. For instance, connecting three 12V EG4 batteries in series without balancing may cause one unit to exceed 14V while others lag, damaging the pack. Pro Tip: Use a BMS with per-cell monitoring for series configurations.

How does series configuration affect EG4 battery lifespan?

Series configurations stress batteries unevenly unless rigorously balanced. Cells with slight capacity variations discharge at different rates, forcing weaker units into deep discharge cycles. Over time, this accelerates capacity fade. A real-world example: A 24V system using two 12V EG4 batteries might see 10% faster degradation in the lower-capacity unit. Pro Tip: Rotate battery positions in the series chain periodically to distribute wear.
