Why choose it

The LP12-300 combines high energy density with robust safety features. The built-in heating mat automatically warms the cells when charging in temperatures as low as -20°C, preventing lithium plating and extending battery life. The Bluetooth BMS provides real-time data and diagnostics, eliminating guesswork. With over 4000 cycles at 80% DoD, this battery outlasts traditional lead-acid by a factor of five, reducing long-term cost and maintenance.

Ideal use cases

• Off-grid solar energy storage for cabins and remote homes
• Marine house banks for sailboats and yachts
• RV and campervan auxiliary power systems
• Backup power for critical loads

Good to know

The battery supports up to 4 units in series (48V system) and 4 in parallel (1200Ah). It charges at temperatures from -20°C to 45°C with the heating function active, and discharges from -20°C to 60°C. Self-discharge is less than 3% per month, ensuring readiness when you need it.
