2 Pack 12V 140Ah Lithium LiFePO4 Deep Cycle Rechargeable Battery,Built-in 100A BMS,5000 Life Cycles, Perfect for RV,camper,Marine,Off-Grid,lighting,Overland. - PYXMGSHMY, 12v140ah 002

• 🌟【1/3* Lightweight】LiFePO4 Battery Weighting only 32 lbs for one module, it’s weighs only 1/3* the weight of lead acid batteries. The 12v100ah and 12v140ah LiFePO4 batteries are the same size but different in weight. 🌟【10 years life】12v 140ah LiFePO4 battery provides 5000-7000 cycles (10 times longer) and 10 years life compared to 200~500 cycles and 3 years life of lead-acid battery. Because of its safety and stability, LiFePO4 battery can perfectly replace the traditional lead acid battery. 🌟【Slow Power Loss】 : LiFePO4 battery have high energy density, which makes it possible to ensure long-term recycling. The capacity of the monomer is still greater than 80%. This model can be repeatedly charged and discharged without any memory effect. 🌟【100% Protection】: The built-in 100A BMS (Battery Management System) protects the battery from overcharge, over-discharge, over-current，and short circuits with excellent self-discharge rate. 🌟【 Capacity Expansion】 : Our LiFePO4 lithium ion battery supports to be connected in parallel and in series to expand its capacity or voltage (Max. in 4 series& 4 parallel).
