http://www.applestone-utv.com/435071012 ... -batteries is now importing bare 200 AH LiFePO4 cells - The first eight, I have purchased, capacity and internal resistance tested then passed on at my cost to get some into the market. Four cells make up a 200 Ah battery @ $300 each making the pack $1200. The only additional cost would be an HA02 Balancer (about $60.00 from Aliexpress) , about 300mm of 15mm copper pipe to cut, flatten and drill to make cell connecting plates and eight 6mm x 10mm stainless bolts and washers - making the battery about $1260 all up. The capacity test was performed charging and discharging each cell individually from 2.9 v to 3.5 volts. All cells were very close in capacity with a low of 203 Ah and a high of 208 Ah. The sixteen cells that have been supplied have both been fitted to new European motorhomes - each fitting a pair of 12 volt units giving a 400 AH pack for just over $2500.00. The supplier will keep on hand a few replacement cells should any warranty claims occur. At this stage there is a 24 month warranty in place but he is negotiating with his supplier to extend this to five years - with some conditions.
With a battery set up like this should in the unlikely event a cell should fail, it is a relatively easy task to replace a single cell.
