4S 12V 280AH/304Ah/314Ah/320AH DIY Battery kits, BMS included, Active balancing

12V lead-acid batteries(AGM) are widely used in RVs, trailers, and trucks as power sources for lighting, water pumps, fans, refrigerators (12V models), air conditioners, and other onboard electrical appliances.Due to its low cost, adaptability to a wide temperature range, simple maintenance, and compatibility with vehicle 12V circuits, it is widely welcomed by car owners and manufacturers.

However, lead-acid batteries have the disadvantages of large volume, low energy density, small capacity, and few cycles. A 12V lithium battery can compensate for these disadvantages. Lithium batteries are increasingly being used in 12V power supplies for RVs and trucks.

Here’s a clear comparison between 12V Lead-Acid Batteries and 12V Lithium Batteries (e.g., LiFePO₄) in table format:

Deligreen 12V kits suits LiFePO4 cell 280ah-314ah,including EVE,CATL,REPT,Hithium,CALB,Lishen etc.

EVE 304ah is a HSEV grade cell that features constant 0.5C 152A charge/discharge,Peak 2C charge and 3C discharge for 60 seconds.

It can complete fast charging, instant high current discharge, and meet various needs of in car vehicles.
