Deep Cycle Lithium Battery With APP Monitoring
Saintish 12.8V deep cycle lithium batteries are with similar dimension as lead acid batteries, but it is only 1/3 of the weight of lead acid, and delivers twice power, the max.continuous discharge current up to 100A.
The built-in battery management system can monitor each prismatic cells status during battery working. It protects the lithium battery from over charge/discharge, over temperature and short circuit.
The deep cycle lifepo4 batteries accept maximum of 4pcs in series connection or 4pcs in parallel connection in order to increase the overall capacity.
Saintish deep cycle battery provides 5 years full replacement warranty.
