@Fosterqc I feel like anyone that wants a cheap ebike would want one. This pared with a Bafang mid drive would be sweet.

I have a really heavy duty 26" rim full suspension downhill mountain bike that prob cost a shit ton when my step dad (who races for a team) got it like 12 years ago.
Its just waiting for a 26" hub motor or two. Not sure where to buy them from. I really want to pick up a used one semi locally. Need to post on endless sphere or somthing.

I notice that the listing says to measure full voltage you have to real from several pins, so I am assuming that means more than just the + and - pins have to be hooked up to be able to get these things to make some go. Anyone have any ideas?
Also, what are the folks who bought these thinking for connecting to the outputs? Copper tabs into the terminals? Pull it open and solder some 10ga to the pack- and pack+?

Iām thinking I might tear the 13th cell out and run it as a smaller and lighter 12S, then it can be paralleled to a internal 12S battery instead of using a booster. I know you can still hook a 13S up to a 12S but Iād rather not.
given the construction, on second thought Iāll probably leave it intact if I can.
My roommate and I are looking at these for plug and play ebike packs. That price is just insanity

snatch em up quick. Maybe I should have got 2ā¦
@Fosterqc no taxes and free shipping. Buy another . Also they each ship separately, each with its own tracking number.
@BenjaminF I think Iām going to open them up and solder wires for ebike use. But I also want to make a 3D printed base that they can plug into thatāll have an ac inverter and step down converter. So I can have a portable wall outlet, or portable board charger/ lab supply.

Anyone know what the charge voltage on these would be? We are talking 13s, but as @Scepterr says,
Would that change what charge voltage I should be targeting when buying a charger?
all shall be answered inā¦ 15 or so hours lol

I might not be able to resist that buy button and the fear of missing out till then, but either way Ill be waiting for your teardown (so that I can see what I got myself into after having bought three )

I really think they will be 13s. In this part of the slide show they are testing 39Ah cells and the pics show they were at 4.18v. Still cannot wait to find out for certain.

Think these packs would be a great DIY Powerwall alternative for the price?

100%, itās 11.38wh/$1 @$87(too lazy to redo at $89)
assuming full capacity
already assembled and at 48v which is great for inverters and probably decent BMS built-in

my avg price for salvaged 18650 was 10wh/$1 and thatās not counting all the dead cells and alllllll the labor

Thatās what I was thinking. Seems like a quick/easy solution. @Scepterr
