Battery Management Board
Charge and Discharge your lithium deep cycle batteries in series or parallel. The choice is yours!
You can also place the batteries in any position, even upside down. That is the beauty of lithium batteries.

Prismatic Cells
Lithium batteries can hold a charge for 6 months or longer. They only lose about 2% charge each month.
The prismatic cells that we use help us to have less connections which improves quality.

2000+ Cycles
Our lithium batteries are good for 2,000+ charges or discharges at 100% Depth of Discharge.
With lead-acid batteries you can only really use about 50 percent capacity and get 200-300 cycles.

Our Customers Matter
Received my lithium battery days after ordering. Best battery I have used. Thank you for helping me pick out a great charger and working with me to protect my alternator. I will only buy from you from now on.
I am really enjoying the batteries in my golf cart. Thank you as this was a lot easier than I thought it would be when I first started looking for lithium batteries.
