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! :shock:

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 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?

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!! :roll:
WHere does this "4300" come from?!?
