⚡ Installation Guidance

For best performance, ensure all cables in your battery system are equal in length.
Mismatched cable runs can cause:

• Uneven current sharing between batteries
• Localised heating and voltage imbalance
• Reduced efficiency and shortened battery lifespan

Equal-length cables ensure balanced discharge, stable operation, and maximum efficiency under high-current loads.
