Help...Can anyone ID this battery pack?

[TheeBigGuy]

A guy is selling this battery for $500.00.. It says it is 48volts 66amp hours at 3kw.... I'm sorta new to this so I would like as much info as I can get before I take the risk to purchase it...He has more than one...I will happily provide a link if it is a valid deal...Anyone know what it is?...thanks..How would I test before buying?

Does it include a BMS? What is the BMS rated for? Charge amps, discharge amps?

Those are 14S Lithium NMC chemistry. Each piece is two cells.

It's the burny-explodey type of Lithium chemistry.

I like to think of that as a perk. Good for 4th of July.

2nd gen Leaf modules.

those are first gen leaf modules. (sardine can style) vs the 2nd gen which have a white plastic inner part with no "lip"

That pack looks like the ones that tech direct sells. (the one in the link is 2nd gen cell option but they also have sold the 1st gen in the past)

first gen...Probably pulled from higher mileage vehicle...figure half the rated capacity...3 kWh likely means 1.5 kWh...

if space/weight not an issue not a big deal but also not as great of a deal...
