Hello, off grid for 30 years. Environmental laws prevent me from buying used lead acid as I have for this whole time. I am also tired of lead acids.

I am planning to buy some Lithium Batteries from China, off Alibaba.

Can someone recommend a supplier please.

I really just want to hear from people who have successfully done it and are happy with their batteries.

Thanks george

curious to see what folks say... we 'almost' did that, but back off in favor of some dirt-cheap AGMs we got a line on.  Hard to bite that lithium bullet :/  Make sure they're the right kind of lithium, too!

You may want to be a bit more specific, what size, chemistry, and application do you have in mind?

I have a set of 8 Sinopoly 400AH LiFePO4 cells, but have only had them 3 months; much too early to say that I'm happy.

Getting satisfactory connections has been a bit problematic. The bus bars as included were of a length that only worked for half the connections; the cells are 'packaged' in pairs with metal strapping, and bus bars only fit the strapped pairs, not between the pairs.

I made my own bars for the other connections. So far things are working fine after retorquing twice, but as I am still waiting on my inverters there has never been a heavy load to tax the connections.

Documentation was very sparse. Warching voltages approaching full charge, a couple cells are obviously the weakest link.

I bought through a localish reseller, so can't comment on the direct purchase experience.

What size d you want?
I installed a POMCube NetZero storrage system late last year. and the lithium battery they use on it seems working great.

Evtv/Ev motor verks store has a locking fastener system to combat that exact issue.

Not sure if they sell just the washers. NordLock.
