If the BMS makes them true drop ins, they should work with my GoPower 3000 I/C and Blue Sky solar charge controller.

The price should come down some by the time I need to buy again.

You got there too late to see my head and shoulders tucked into my battery compartment feverishly trying to complete my installation to keep the peace in the house. If you are coming to the Coos Bay we will be there. I went a DIY route for a couple of reasons. But to put in 700AH of one of the drop-in replacements was not what I wanted to spend. It also helps to be a techno geek.


If you at some point decide to go LiFePO4 your present I/C and solar charger will be fine. If you do not already have a shunt with I/C you might want to add one so you can accurately measure total amps in and out of the battery bank. The lithium voltage curve is so flat that voltage is a poor metric to measure state of charge.



If you happen to be in the RGV over the next two months give us a shout.
