CHEMISTRY COMPARISON MATRIX

ECOCHARGE: Deep Cycle Gel OPTIMAL CHOICE
High Safety Zero Maintenance Good Heat Tolerance
Alternative: Lithium-Ion Too Expensive
Best Density High Cost ($$$) Thermal Risk
Alternative: Flooded Lead-Acid High Maintenance
Toxic Fumes Regular Refilling Short Life

Wiring & Breaker Safety

The system is protected by a multi-stage safety protocol to prevent overheating and short circuits.
