Theses no other way to go (DIY LifePo4)

This is just to celebrate how good these things work. I had SLA bank I replaced a week ago. You just can't beat them. No more generator! No more worries!

Over the last year I've switched from lead/acid to lithium, couldn't be happier. I put it off for several years waiting for a good, reliable supplier of high quality cells, but then Docan started shipping from US stocks and I started buying. Currently up to 2400 ah at 24 volts in the system.

I love the way they charge, they just suck down the power until they're full, unlike the lead/acid that seem to take forever to get that last 10 percent into them. I love never having to worry if they're regularly hitting float voltage, in the long cloudy winter here that can be a real issue. Basically, I just don't have to worry about them like I did with the lead / acid.

Amen! I have just 28KWH in two banks this far. My supplier has been Amy Zheng from Docan. I just can't believe the performance!

I built for expansion, and intend on building at least four more banks.
