RV Lithium Batteries

1/3 Space Saver
4,000+ Cycles
Zero Maintenance

BSLBATT 12V lithium RV batteries are built for RVs, campers, trailers, and off-grid systems. The slim form factor takes up one third less space than a conventional battery box, and LiFePO4 chemistry delivers stable output across more than 4,000 cycles without maintenance.

Key Features of BSLBATT 12 Volt Lithium Battery for RV Use

Long Cycle Life

Both models are rated for more than 4,000 cycles at 80% depth of discharge. At one cycle per day, that covers over ten years of regular use — significantly longer than the 300 to 500 cycles typical of lead-acid alternatives.

Space-Saving Design

The 100Ah model stands just 65 mm tall and the 200Ah at 70 mm, taking up one third less space than a conventional battery enclosure. Both fit under-bench compartments, floor cavities, and side storage areas in caravans and camper trailers.

Solar Ready

The 9.2 to 14.6V operating range is compatible with standard MPPT solar charge controllers. The battery accepts maximum current from your panels under varying light conditions, ideal for continuous off-grid use.

Built-In BMS Protection

Each unit uses 3.2V LiFePO4 cells in a 4S1P configuration with a built-in BMS. Short-circuit cutoff responds within 10 ms, with peak fault currents of 1,200A (100Ah) and 2,500A (200Ah).

Lightweight and Efficient

The 100Ah model weighs 15 kg and the 200Ah model 28 kg. Higher energy density makes both units noticeably lighter than lead-acid equivalents, reducing vehicle load and improving fuel efficiency on long trips.

Wide Temperature Range

Discharge is rated from -20°C to 60°C, charging from 0°C to 55°C, with humidity tolerance of 60±25% R.H. Suitable for cold-weather camping, hot climates, and coastal environments.

FAQ

What scenarios are these 12V lithium batteries designed for?

RVs, campers, trailers, and off-grid installations. The slim profile and wide operating temperature range make them well suited for touring vehicles and seasonal use.

Can I connect two units in parallel to double capacity?

Yes. Both models support parallel connection. Use cables of equal length and matching cross-section to balance current distribution between units.

Are these batteries compatible with MPPT solar charge controllers?

Yes. Set your controller to a lithium profile with absorption voltage no higher than 14.4V and float voltage between 13.5 and 13.8V, within the recommended discharge window of 12.0 to 13.8V.

How long will a 12V 200Ah lithium battery power a typical RV load?

At an average draw of 15A covering a compressor fridge, lighting, a fan, and USB charging, runtime is approximately 10 to 11 hours at 80% usable depth of discharge. Adding solar can extend that through the day.

What warranty comes with BSLBATT lithium RV batteries?

Both models carry a 5-year product warranty. Design service life is rated at 20 years under standard operating conditions.

How many solar backup batteries do I need?

A single 10kWh unit covers average overnight consumption for most mid-size households. For whole-home backup or off-grid use, multiple units can be added in parallel without replacing the existing system.
