Can I trust these high-power ebay cells?

[AviatorTrainman]

I was trolling ebay looking for some possible cells for my electric motorcycle conversion, and found this: https://www.ebay.com/itm/84-SPIM08H...938579?hash=item2f38b65dd3:g:MuYAAOSwDkVaakSh. Can I trust these cells? The description says they came from an electric city bus prototype. They seem like an amazing deal at over 6 Wh/$, and if they can withstand the rated discharge, I will never have to worry about overheating my pack. The only other source I've found that comes close to this in terms of watt-hours per dollar is used first gen Nissan Leaf modules, and I'm having trouble finding any concrete data for max. discharge rate on those.

You wont know for sure without testing a few yourself.
BUT, you should also check the reality of “free” shipping ... it getting very tricky to ship quantities of cells legally.
But you could always organise a road trip to pick them up.
Leaf cells.? Have you searched this forum for the Leaf cell test data thread ?
Early Leaf cells have a poor reputation for capacity loss, so would need to be carfully selected, and very cheap to offset the risks.
GM/LG Volt cells are a much better option.

2.4kW for $400 so $160 per kW and you still need to build the pack

Is that really so cheap for used cells?

Anyway no risk involved, if you have the right testing gear and skills to use it, just do testing of a random sample upon arrival.

If not as advertised, ebay / PayPal refund your money, seller has to pay shipping back.

Do NOT pick them up!

No warranty at all if you do that.

The shipping business is 100% their problem, in both directions.

Where might I find a better deal? I'm not seeing much that has a comparable $/Wh ratio.

Dunno, but unless used is 70-80% cheaper, I'd advise saving up until you can afford new.

Or throw the dice, might get lucky
