Literature on Bestgo LiFePO4 batteries?

[jumpjack]

Have you ever read/heard about Bestgo batteries performance?
Vendor talks about 4,300 cycles and 3-5C, and pack I need would cost half w.r.t other solutions!

I'd buy them if I knew enugh data baout them!
About the terminations, I think they're designed for screws, aren't they?

I have a 10ah battery that needs at least two cells. I might get a couple of these to try out.

I saw these batteries too. I googled the owner, Carl, and he seems to have an honest reputation and respectable knowledge about e-car conversions. However when I asked him about details of a 60V 20 a/hr pack he wasn't too sure. For instance he said the pack would weigh 10.5 lb (way too low). And the price kept changing. I kind of doubt I would get what I actually order.

240Wh/kg?!? Cool batteries! :lol:

Well, actually Panasonic has 250 Wh/kg batteries (NCR18650A), so this would not be impossible...

Did you see their 20 a/hr single pouch cell for $32? I was thinking of getting 20 of them and using a 60v ping board. I could probably do the work myself. But the shipping is another question. Does anybody know if the tabs can be soldered?

Yeah, they have amazing/suspicious prices...

If these "Bestgo" cells are from Bestgopower, Huston we have a problem!

Cycle Life(23°C, at +/- C/3 rate)
≥2,000 times @ 80%DOD
≥1,500 times @ 100%DOD

A 40Ah would last 2000 cycles only if you pick from it just 13A!!
WHere does this "4300" come from?!?
