Overview
Lighter, longer-lasting, and safer than lead acid — built for the long run.
This 12V 100Ah LiFePO4 lithium battery is a drop-in upgrade for anyone still relying on lead acid — delivering up to 15 times the cycle life, 40% of the weight, and significantly higher efficiency. Whether you're running a small solar setup, a UPS, or backup power for essential loads, it's built to outlast and outperform traditional batteries while taking up less space and effort to maintain.
Why this LiFePO4 battery
- Up to 15x longer cycle life — rated for 3,000+ cycles at 0.2C to 100% depth of discharge, versus a few hundred cycles for lead acid.
- 5x longer calendar life — stays healthy in storage far longer than lead acid, even with infrequent use.
- 40% of the weight — roughly 60% lighter than a comparable lead acid battery, making installation and handling significantly easier.
- Faster charging — shorter charge times mean less downtime between cycles.
- Low self-discharge — holds its charge longer in storage, so it's ready when you need it without constant top-ups.
- Higher round-trip efficiency — delivers ~92% efficiency versus ~80% for lead acid, meaning more of every charge cycle is usable power.
- Multi-layer protection — built-in safeguards against overcharge, over-discharge, and short circuits for safer long-term operation.
- Reliable in real conditions — rated performance from -10°C to 40°C, with predictable capacity even in cooler temperatures.
