【Lightweight and Compact Design】12V 200Ah LiFePO4 lithium battery is 1/3 lighter than the same capacity FLA,only 48.5lb. Though lightweight,it has a high capacity density and performs well.Specifically for trolling motor,RV,Off-Grid,home solar systems, emergency backup power systems, marine boat and RV trips. BMS, 【5000+ Deep Cycle】More than 5000 cycles under 100% discharge condition and more than 8500 cycles under 50% discharge condition, at least 5 times more durable than FLA. With the FLA,you need to remember this or that, or if they got a full charge today,go check the electrolyte, gotta run to the store and get 12 liters of distilled water.With the LifePo4, you just hook it up, set the proper voltages and currents in your charger/inverter and basically forget about it., 【Built-in 100A BMS Protection】Built-in 100A BMS with a continuous charge and discharge current of up to 200A and a peak discharge current of 400A 5s, supporting 2536W load power. The BMS also has a variety of protection functions to prevent battery failure due to overcharge, overdischarge, overcurrent, short circuit and high temperature.It also has automatic battery cell balancing function! low-temp protection -20°C ,Extend the service life of 12V 200Ah battery., 【Support Up to 4P4S】It can be expanded to 4 in series or 4 in parallel for higher voltage (up to 48V) or larger capacity (up to 800Ah).Can be wired in 2S2P for a 24v 400Ah system,leaves you with no regrets to safely power all your loads: washing machine & dryer, dehumidifier, fridge, and various other items - all at the same time.It can be widely used for home solar systems, emergency backup power systems, and RV trips., 【5-year Warranty and Local Services】We have local warehouses in the US East and US West, offering a five-year warranty and professional after-sales service.
