Fuck me I bough 100 cells years ago at $6/cell. And that was a crazy good deal! New cells though.
These cells might be really really really old. But at $1/cell, wow. Iām very tempted.

fyi for me it says shipping for one is $29.83, shipping for five is $82.70, shipping for ten is $118.80
shipping just for one kills the deal ($1.69/cell), but for five it works out to $1.39/cell, for ten it works out to $1.29/cell

Do we wanna get 5 of em them? My only issue with these cells is that they are huge! And the capacity is not great.

i agree, itās a deal in search of an application. the worst way to buy esk8 equipment. butā¦ $1.39/cellā¦
also i canāt remember who posted recently here that it took them forever to breakdown the 4s4p submodules

Yeah I feel like I would rather pay 2.7 per cell for the QB26800, that have triple the capacity of these

Personally, I think that if we could figure out the BMS, we could use the packs as-is, rendering these amazing value. If you and @sesat want to do this, I am on board too.

i think they are huge though, not sure if there is space for bindings if the pack is placed between the feet. i thought i once saw a pic on this site of the pack laid on top of an mtb deck, but i was too high to remember who posted it or in which thread. i think someone joked about just attaching the trucks directly to the pack
i expect the bms for a ups to have modest current output, and be tough to bypass, but i best do some digging before jumping to conclusions
hold up let me watch https://youtu.be/3jPYyGjWqck iāll be back in a few

haha, sounds like a good idea for Bustinās āskate everythingā challenge. They did actually do just that to an old TV ^^
That should be the expectation, but look at those fat busbars - why would they use so much copper if it werenāt designed for high discharge?
Yeah Iām thinking I need to get another hummie deck and a single stack enclosure to make a 16S2P with them as they wouldnāt fit well in my double stack enclosures.
Or perhaps I could use one of my torqueboards decks, maybe I should get another one of those.

Yeah, this is what they are best for, imo. I put one of these together for somebody and plan to build a couple more since that turned out so nice. Hummie deck, 12S3P (could have fit 13S3P) A123 M1B, 30A/5065 motor, etc = a really solid deck for ~$650 all in, charger and everything. Did 35 mph w/ a 200lb rider np and got almost 20mi of range while cruising responsibly (but still quickly) on 97mm thane."
I think the extra P group is well worth it over the additional V of 14-16S since these sag so little compared to liions.

Photos plz! 15s2p (30 cells) barely fit singlestack for me. Btw itās 15s because hummie motors, wanted a bit more speed. Also, no room for more cells.
I would not go 16s.
