lithium battery 12v 100ah

12V 100AH LiFePO4 Battery 1280Wh Low Temp Charge & BMS 100A ~200A

Lithium iron phosphate batteries are impressive because of their durability, longer cycles, and less thermal runaway. It has more five times cycles than LiNiCoMnO2 and is more lightweight and more environmentally friendly than a lead acid battery.
CMB deep cycle lifepo4 battery has built-in BMS to protect it from overcharge,over-discharge, over-current, and short circuits. With high-temperature cut-off and low-temperature charge protection.
The lithium ion deep cycle battery is manufactured by grade A LiFePO4 cells with high energy density, no memory effect, more stable performance, and greater power. Supporting IP66/IP68 waterproof and max 4 series connection and limited parallel connection. Batteries must be the same voltage before series and parallel.
Lithium-ion battery 12V 100Ah (LiFePO4) can support Bluetooth and UART or 485 communication.
Our 12V 100Ah smart lithium iron phosphate battery provides 10% DOD > 6000 cycles, and 100% DOD > 2000 cycles.
The lithium iron phosphate battery 12V 100Ah is perfect for marine, camping, fishing, solar off-grid systems, and backup power.
The Li-ion battery with low temp cut off protection (charge)-10°C~0°C and low temp cut off protection(discharge)-20°C~4°C.

Protecting the BMS in Parallel Connection

When connected in parallel, the battery with high voltage will charge the low voltage. The instantaneous high current can destroy the BMS in 0.01 seconds, so the CMB lithium iron phosphate battery will be equipped with a current limiting module so that your battery can be used in parallel for the RV and yacht, or you can stop the parallel system at any time and carry one of those to your campsite.

IP67 Test For CMB 12V100Ah-A

After testing, the CMB 12V100Ah-A can work normally in a humid environment without interference. Even if it is placed underwater for half an hour (IP67 test), the inside of the battery remains dry, which means that it can be used on a boat Even if the CMB battery pack falls into the lake, it will not cause damage to the battery and BMS.
