Safety and protective circuitry
The battery uses individually fused LiFePO4 cells and an advanced BMS to ensure optimal protection. Over‑charge protection detects 3.75V ±0.03V with a 1000 ms delay and recovers at 3.55V (min 3.40V, max 3.60V). Over‑discharge protection engages at 2.20V ±0.08V with a 1000 ms delay and recovers at 2.70V ±0.10V. Short‑circuit protection is inherent, supporting safe, repeated cycling in variable conditions.
Applications and use cases
- RVs, motorhomes, and caravans
- Boats and marine systems
- Off‑grid cabins and remote installations
- Vans, trailers, and other mobile power needs
