HIGH-OUTPUT PROTECTION

150A Smart BMS.

More Power for 12V Loads.

The 150A smart BMS delivers stronger continuous output while monitoring battery status in real time. It helps protect against overcharge, over-discharge, overcurrent, short circuit, and extreme temperatures — giving your RV, marine, solar, and backup system more usable power with safer control.

Cold-Weather Ready

The smart BMS pauses charging at 32°F / 0°C and resumes at 41°F / 5°C to help protect the cells. Discharge protection works down to -4°F / -20°C, making it ready for cold RV, marine, solar, and outdoor power use.

FAQs

Still have questions?
Find more information in our FAQ.

1. What is the LiThink 12V 100Ah Group 24 battery best used for?

The LiThink 12V 100Ah Group 24 LiFePO4 battery is a compact lithium upgrade for RVs, camper vans, boats, trolling motors, solar storage, garage power, and backup systems. Its smaller Group 24 case makes it easier to install in space-limited 12V setups.

2. What makes this Group 24 battery different from a standard 100Ah battery?

This battery combines a compact Group 24 size with a 150A smart BMS, 550A surge support, Bluetooth monitoring, self-heating, IP65 protection, and reinforced internal structure. It is built to deliver stronger, smarter 12V power than many basic 100Ah batteries.

3. What does ECE R10 compliance mean for real-world use?

ECE R10 means the battery has been tested for electromagnetic compatibility in vehicle electrical environments. For RVs, vans, and mobile power systems, this helps reduce interference concerns and supports more reliable operation around other onboard electronics.

4. How does the self-heating function work?

When charging below 41°F / 5°C, the built-in heating system starts automatically and warms the cells to 50°F / 10°C. This helps make cold-weather charging safer and more reliable. The BMS also pauses charging at 32°F / 0°C and resumes at 41°F / 5°C to help protect the cells.

5. How capable is the 150A BMS for high-load use?

The 150A smart BMS supports up to 150A continuous discharge and multi-stage surge output up to 550A for short start-up peaks. It is suitable for many demanding 12V loads, including RV appliances through an inverter, marine equipment, pumps, and backup power systems.
