12.8V 100Ah LiFePO4 Battery | Inverter Battery Backup

  Our RLB 12V 100Ah lithium-ion batteries are designed with Lithium Iron Phosphate (LiFePo4) technology to deliver twice the power and half the weight of sealed lead-acid batteries, and last four times longer than sealed lead-acid batteries, resulting in a very long life.

Our M-Series batteries are high-performance dual-purpose, deep-cycle batteries that can handle both start-up and cyclic operations. This battery can be used as a home battery to power peripherals, accessories, and other onboard needs. The perfect compromise between the unique demands of low current consumption service.
  100ah capacity can power high amp traction trolling motor all day or power your RV on the open road all day. Ideal for deep-cycle applications, such as traction motors, solar storage, or boating, where a lot of power is used over long periods. The RLB series battery offers installation flexibility and requires no maintenance over the life of the battery. It maintains a stable power supply and comes with an M8 terminal type and a built-in Bluetooth-monitoring smart battery management system (BMS).

Q.  What are the advantages of a lithium battery compared with a lead-acid battery?

A: Compared with large batteries such as lead-acid and nickel-cadmium, lithium-ion batteries do not contain cadmium, lead, mercury, and other elements that cause environmental pollution. When charging, it will not produce a "hydrogen evolution" phenomenon similar to a lead-acid battery, and will not corrode the wire terminal and battery box, which is environmentally friendly and reliable. Lithium iron phosphate battery life of 5~10 years, no memory effect, no need for frequent replacement; 2. The same charging and discharging port and the same Anderson plug have solved the major safety problems caused by different charging ports that the forklift can start when charging; 3: lithium-ion battery pack is equipped with intelligent lithium battery management and protection circuit, which can effectively cut off the main circuit automatically for low battery power, short circuit, overcharge, high temperature and other faults, and can alarm with sound (buzzer) and light (display). The traditional lead-acid battery does not have the above functions; 4: multiple security protection. An intelligent monitoring and protection device is installed in three places between the battery, the total output of the battery, and the output of the main bus, which can monitor and protect the battery in real-time.

Q. What kind of batteries is suitable for use in a caravan?

A: Large-capacity lithium iron battery + solar + generator, is now the caravan can think of the best way to use electricity, if a little save a little, basically will not encounter the dilemma of no electricity available. Now the world is mature on the 48V + lithium solutions!


Q. Why are few self-driving mobile power portable high-capacity outdoor camping emergency lithium batteries?
A: Self-driving food solutions, 1. Inverter power + battery; 2. wood stove; 3. gas stove alcohol stove and so on. These solutions have their advantages, but the disadvantages are also obvious. Why do people use 220V mobile power portable high-capacity outdoor camping emergency lithium batteries, although this kind of battery is more expensive, but can store 1 to 2 degrees of electricity, you can use high-power appliances, parking can also be used in lighting, stereo, etc., is the most ideal, safe and convenient solution.
