TEMGO 12V 300Ah Self-Heating LiFePO4 Lithium Battery with APP Monitoring | Low-Temp Protection, Built-in 200A BMS, 3840Wh Energy, 5000+ Cycles, for RV, Camper, Solar, Off-Grid
A 12 V 300 Ah (3,840 Wh) self-heating battery that charges down to -4 ℉ (-20 ℃), with a 200 A BMS, Bluetooth app, touch screen and M8 terminals, and it can be mounted on its side. Its capacity is higher than most 12 V batteries listed, and the touch screen is uncommon. The 1-year warranty is much shorter than the 5 years common here, so it suits cold-weather RV and off-grid use.

Features
Details from the TEMGO Amazon listing:
- 【Massive 300Ah Capacity & Reliable Low Temp Protection】Built with high-quality LiFePO4 cells, this 12V 300Ah lithium battery delivers stable performance, higher energy density, and over 5000 cycles. Includes low-temperature cutoff to protect battery health in freezing conditions.
- 【Smart APP Monitoring】Temgo 12V 300Ah Lithium battery has a more user-friendly design with a smart APP that enables you to instantly view crucial data such as remaining battery level (State of Charge), voltage, current input/output, power usage, and estimated runtime. By monitoring usage patterns and health data, you can make informed decisions to operate your battery within its ideal range, maximizing its lifespan and overall performance. Just download our TEMGO APP on the phone according to the instructions.
- 【200A BMS for Superior Safety】The advanced 200A Battery Management System (BMS) safeguards against overcharge, over-discharge, overcurrent, short circuits, and overheating. And the 100% Recycled post-consumer acrylonitrile Butadiene Styrene (ABS) (RM0271) material does not contain any heavy metals or rare metals, making it more environmentally friendly, safe, and stable — no risk of fire or explosion.
- 【Self-Heating for Cold Weather Charging】Built-in automatic self-heating activates when battery temperature drops below 32°F (0°C), ensuring safe charging even in freezing conditions. Heating stops once the battery reaches 41°F (5°C), then charging begins.
- 【Versatile Use & 1-Year Warranty】Install in any direction without leaking or damage. Ideal for RVs, campers, solar systems, and off-grid setups. Backed by TEMGO’s 1-year warranty and responsive 24/7 customer service for peace of mind.
- 【Performance & Compatibility Notice】Voltage and current readings may vary by approximately 1%–5% depending on temperature, measuring equipment, and actual operating conditions. For series or parallel connections, please use batteries of the same brand and model only; mixing different batteries may cause imbalance or trigger BMS protection.
