I purchased 4 x 100Ah Lithium batteries about a year ago, and since then I stopped having weekly power cuts. So I purchased them for nothing, as the
4 x 100Ah DC Gel batteries are working just fine.
I would end up using the Lithium's at some point ( going off the grid on one phase when electricity prices start getting more steep), so for now I need to know where I can give my batteries a boost charge OR maybe I can just buy one.
Can someone please kindly point me in the right direction.
