Product Description
LFP1280MH VMAX Lithium Battery with Internal Heater
Designed with lithium iron phosphate battery (LiFePO4) technology, this is a battery built to last year after year. A built in internal heater allows this battery to be usable and chargable in below freezing temperatures.
- Self heating lithium battery for safe charging below 32°F (0°C).
- High energy density and light weight at only 18 lbs for 80Ah.
- High efficiency, fast charging.
- Built-in BMS offering voltage, current and temperature protection.
- Standard Group 24 battery case for an easy VRLA battery replacement.
- 10 years design life, stable performance & maintenance-free.
Recommended uses:
- Trolling motors.
- Solar Power Backup & Energy Storage.
- UPS and medical cart applications.
- RV's, boats, trailers and other demanding deep cycle applications.
- Parallel wiring is acceptable for up to 320Ah of capacity (4 batteries).
- Series wiring is acceptable for 24V, 36V and 48V systems.
- NOT for engine starting applications.
