views on a battery

m3vuv:
Has anyone tried one of these?:https://www.ebay.co.uk/itm/Lithium-48V-36AH-Ebike-battery-pack-100w-hgh-power-charger-new/353136397671,looks too cheap for the ah,what do people think of it,just be good to get folks thoughts on it.

3 parallel cells for 36Ah means 12Ah/cell.

Best 18650 cells on the market are at or under 4Ah.
So this offer is BS.

But with such money it's possible to make such a battery using DIY methods.
Good cells alone would cost close to 100 pounds.
Then the rest.

I would say building your own spot welder and making the battery yourself is still cheaper than buying from any legit offer.
Myself I made 11S6P battery using LG MG1 cells. 200PLN for cells, ~150PLN spot welder, ~50PLN rest (plastic frame, metal strips for the battery).
