LiFeBlue batteries are designed as a "drop in", 12 volt, direct replacement deep cycle battery for Recreational Vehicles(RV), boats, off grid power, back up power and industrial uses. Drop in simply means it is a complete battery package sealed in a standard battery case as seen below. No assembly required like with GBS-EPS systems.

What really sets LiFeBlue apart from all other drop in lithium batteries is the built in battery monitor that communicates with the EMS system. Using the free Bluetooth app called Smart Connect for IOS or Android, (download from iTunes store or Google play) you can view the battery capacity or SoC, health, temperature, current and even the cycle life on a tablet or smart phone. This save's hundreds of dollars for external battery monitor and installation. With an external battery monitor, you can't see what is happening inside the battery which is very important.

We stock 3 battery sizes for 12 volt operation and 5 sizes for Series/Parallel use. In series we can supply 24, 36 or 48 volt systems with up to 61 kWh of energy storage. Available sizes are 75AH, 100AH, 150AH, 200AH and 300AH.

LiFeBlue Battery has a patented case with rugged internal support for the BMS and battery cells. You can use LiFeBlue in your RV, boat, off grid cabin or home, golf carts, telecom or many other uses.

Batteries are in stock and usually ship within 24 hours. You can learn more these amazing batteries or make a purchase today on the LiFeBlue Battery website or click on the battery image below.

Choosing the right battery.

Two important factors to know when choosing a LiFeBlue battery are Current and Capacity.


All LiFeBlue 12 volt batteries have a 100 amp current limit. That means each battery can supply up to 100 amperes continuous duty. More than 100 amps and the built in EMS will turn off the battery within 30 seconds. If you need to use more than 100 amps, place two or more batteries in parallel. Each battery in parallel adds 100 ampere capability. For example, 3 200AH batteries will allow up to 300 amps to flow continuously. LiFeBlue bBattery can also provide up to 350 amps for 3 seconds. This is useful to assist engine starting.


LiFeBlue batteries are rated by their capacity. We stock the 100AH, 200AH and 300AH packs. You can combine same size batteries in parallel to increase your capacity. For example, if you want 400AH capacity, you can choose 4 100AH packs or 2 200AH packs.

We recommend sizing your battery bank so the average consumption is about 50% daily. This will provide a very long life with a good reserve for days when you need to use more power before charging.
