The Lion Energy UT 1300 BT-H is a 12V lithium iron phosphate battery designed for compatible auxiliary power, energy storage, RV power, solar, and off-grid battery systems. It delivers 1,344Wh / 105Ah of capacity with 150A continuous discharge for properly configured deep-cycle lithium applications. The UT 1300 BT-H uses LiFePO4 prismatic cells, supports 3,500+ life cycles at 100% depth of discharge, and can retain charge for up to 2 years without use. Built-in Bluetooth® monitoring lets users check battery status from a compatible mobile device, while the internal heater supports cold-weather charging when the battery is connected to an external live charging source. This battery is for auxiliary power only and is not for use as a starter battery.
The UT 1300 BT-H is designed for supported auxiliary power and energy storage applications. It is suitable for properly designed 12V systems where lithium battery chemistry, long cycle life, charge retention, and lower maintenance are important.
Bluetooth® compatibility allows users to monitor battery status from a compatible mobile device through the Lion Energy app. This helps users check available energy, incoming power, outgoing power, and system status alongside the onboard LED indicators.
The built-in heater helps support charging in cold conditions by warming the battery when connected to an external live charging source. The heating element requires incoming power to function and should not be treated as a standalone self-powered heater.
The UT 1300 BT-H can be configured from 12V to 48V and from 105Ah to 420Ah when properly connected in supported series or parallel battery bank layouts. Battery system design, cabling, charging equipment, fusing, and installation should be matched carefully to the intended application.
The Lion Energy UT 1300 BT-H gives RV owners, solar users, and off-grid power builders a compact lithium battery option for supported auxiliary power systems. Its LiFePO4 chemistry, Bluetooth monitoring, internal heater, and 150A continuous discharge rating make it a practical choice for properly designed energy storage setups.
This battery is not designed for engine starting and should only be used for auxiliary power applications. The internal heater requires an external charging source connected to live current before it can warm the battery for cold-weather charging support.
