Explore Details โ
Triple the capacity for larger homes. Supports full-day off-grid operation when paired with a quality solar array.
Explore Details โCompact wall-mount design for modern homes. Optimized for 48V solar inverter systems with smart charge management.
Explore Details โGolf-cart form factor with lithium performance. Ideal for smaller residential solar setups and solar backup systems.
Explore Details โFrom chemistry to customer support, every aspect of Battle Born battery design is optimized for the unique demands of home solar environments โ where safety, reliability, and longevity are non-negotiable.
Lithium iron phosphate is the safest lithium chemistry available. No thermal runaway risk, no toxic off-gassing โ essential when batteries are installed inside or adjacent to your home.
Battle Born batteries accept charge at up to 100% of their rated capacity, maximizing every hour of sunlight harvested by your residential solar panels โ unlike lead-acid which slows at 80% state of charge.
Rated for over 3,000 complete charge cycles โ equivalent to 8โ10 years of daily solar cycling. That's 3โ5ร longer than premium AGM batteries, dramatically lowering your cost per kWh stored.
Every Battle Born battery includes a sophisticated BMS that guards against overcharge, over-discharge, short circuit, and extreme temperatures โ protecting both your battery investment and your home.
Start with a single 100Ah unit and expand as your energy needs grow. Battle Born batteries connect in series and parallel, letting homeowners build storage banks from 1.28 kWh to 100+ kWh.
Performs reliably from -4ยฐF to 135ยฐF discharge range, with a heated option for sub-zero charging. Ideal for residential solar installations across all U.S. climate zones.
The global residential battery energy storage system (BESS) market is projected to exceed $25 billion USD by 2030, driven by surging solar adoption, rising grid electricity costs, and increasing demand for energy independence. Battle Born Batteries sits at the epicenter of this transformation.
