A Grade Cell: Compared with other sub-standard LiFePO4 batteries this lithium ion battery pack is composed of A grade cells, and the cell terminals of this lithium iron phosphate battery are bolted to deliver higher amperage loads and better current conductivity. Lower internal resistance allows this deep cycle lithium battery to accept charge faster, making this LiFePO4 battery ready to use much faster.

Higher Usable Capacity: All batteries degrade over time, but lithium iron phosphate battery consistently outlast AGM. This lithium ion battery pack delivers up to 2,000 rounds, several times of AGM batteries, which are recommended to be discharged to 50% of the capacity but LiFePO4 battery can be discharged to 80-90%, meaning deep cycle lithium battery/LiFePO4 battery saves money in the long run.

Advanced BMS: Unlike the inferior BMS of other LiFePO4 batteries, the BMS of this lithium iron phosphate battery provides authentic 50A continuous discharge, which enables this deep cycle lithium battery to excel in performance. The lithium ion battery pack’s BMS also include smart balancing, temperature/voltage monitoring, and this LiFePO4 battery is also designed with a low self discharge rate.

Run in Parallel or Series: Due to the limited voltage and capacity of the single lithium ion battery pack, the series and parallel connection of deep cycle lithium battery is needed in the actual use of LiFePO4 battery to obtain higher voltage and capacity. This LiFePO4 battery allows for up to 2 batteries in series or in parallel to achieve desired performance of the lithium iron phosphate battery bank.

Impeccably Safe & Lightweight: Go for this LiFePO4 battery if you want to reduce concerns about the weight and safety of the lithium ion battery pack! This LiFePO4 battery provides 50AH that doubles the power of an AGM with 1/3rd of that weight. And this lithium iron phosphate battery eliminates the risk of explosion.
