Not with 24V, but I'm doing a 4-cell 280 AH LiFePo. Best resource is YouTube videos by Will Prowse and Freely Roaming. They'll make you an expert.

That's crazy cheap for a USA based source.

I'd **really** like to know the Chinese maker of the cells.

Sure they are really new Grade A?

Under $1500 for 4, they're in Chatsworth CA and returned my email question in a few minutes. I'll call them.

Advertised as recertified??? Used higher ah cells that are sold with a lower capacity?
2000kwh??? 12v 150ah is not 2 kwh..Maybe if someone is in the area then they can inspect.

I paid for 272 ah lishen cells $120 / piece direct from china.

Did I get this right? 100 dollars per cell? Didn’t say if new or re-man or used or I missed it. Wonder what shipping is going to be like.

Because the subject was LiFePo I assumed your question was about Lithium batteries generally, not the actual company.

They look legitimate. They have an online presence and reviews of their other products are generally positive.

That said, the price is a little suspicious, less than 90% of comparables.

The spec sheet is squirrely. There's a general lack of information on the batteries and it makes me wonder if these might be factory rejects-that is, cells that didn't meet their original design spec and are being sold at a derated spec. Happens all the time in manufacturing though I don't know enough about these batteries to say that's a thing. And, I'm not sure it would be a bad thing because maybe they have greater capacity, and are just sold as lower capacity. All speculation. It would be easy to confirm with capacity testing, so if you buy them that is something to check.

The other thing is since you are not building this battery you won't know if the cells are balanced from the factory. You'll need a BMS and I'm guessing you'll also need an active cell balancer, which is an extra hundred bucks but will help you squeak every amp out of these.

A lot of money to put down for a 10% discount, without an Amazon guarantee.

A maker with an **excellent** reputation, right up with GBS CATL CALB even Winston.

Even more suspicious.

Let's try and dig up a match among Sinopoly's current (or discontinued) cell models.

I dont know about those kinda small batteries in your link, but I have 6 of theese:
https://www.ebay.com/vod/FetchOrderD...=1017043676026 and we love em. We can run 1.5K all night long and never be below 25v by the time the sun starts filling them back up in the morning.

Looks like the link is from your order page (which only you can access), Rock-N-Ruth. You'll have to link us to the item page instead.
