BSLBATT Lithium RV Batteries are a game-changer for the RV world!

BSLBATT Lithium RV Batteries wants to provide you the ideal experience for your RV trips. RVers have long waited for a better battery solution to get rid of their “battery anxiety”. Not only will our products help you have physical and mental ease, but it will allow you to go boondocking comfortably if you wish. Our team of battery experts is familiar with most of the existing components on your RV regardless if it’s a Class A, Class C, or B van.

Do you have a travel trailer or cab-over camper? Don’t worry. We are experts in those types of RV’s as well. We offer three different 12-volt lithium deep cycle models with solutions that will drop into any size travel trailer or motorized RV. We have an LFP drop-in replacements for group 27, 31, and GC2 lead-acid batteries.

The lithium battery factory BSLBATT® 12V offers high-level safety through the use of rhombus cells in Lithium Phosphate technology (LiFePO4 or LFP).

Thanks to its technology, the BSLBATT® 12V Lithium RV Batteries can be installed in any position (vertically, lying on the side or head down).

The electrical parameters of the BSLBATT® 12V Lithium RV Batteries are compatible in all respects with those of an AGM lead battery of 12V. In the vast majority of cases, the charging system can be kept the same and no additional accessories are required to perform the replacement.

The products BSLBATT® are light, compact, efficient, and can be used for all types of uses and applications. BSLBATT® are designed to drop-in replacement of old generation batteries (Lead VRLA, AGM or OPZ batteries) in 12V, that is low performance and harmful to the environment (use of heavy metals and acid electrolytes).

 Extremely long cycle life: the capacity is over 80% after 1C charge and discharges under 100% DOD condition for 3500 cycles, design life up to 15 years

● Cost-effective: thanks to very high discharge voltage platform (above 12 volts) and stable discharge curve, our LiFePO4 battery pack 12.8V/90Ah≈lead-acid 12V/150Ah battery, vary base on different load, it’s especially favorable to the high voltage cutoff application.

 Water-resistant body: IP65 rated

● Ultra-Safe: the LiFePO4 battery pack has more thermal and chemical stability, is widely used on E-bus and backup storage battery system in telecom, also built-in a short circuit, over current, overcharge, over-discharge, and over-temperature protection.

● Also using UL94V-0 fire resistance material on the plastic case

 Environment friendly: no pollution or environmental hazard, mandatory recycling does not require.

 Very lightweight: only one-fourth of an equivalent capacity lead-acid battery.

 Extendible: easy to be extended in parallel or in series to get more capacity or higher voltage.

● Maintenance-free: no need to maintain the battery regularly.

● Compatibility: it can be easily connected with the same battery charger, inverter, or electric appliance like a regular 12-volt lead-acid battery since they have very similar voltage and same terminals.
