4 ea 7.61 kwh battery packs

[justoneguy]

I just purchased these 4 samsung battery packs. 2 never used 2 only a few cycles
A total of 88 cells Lithium NMC 3.7v 94 ah 22s1p
I'm not sure what to do with 30+ kw.
I have a 7.5 kw 12.8v system in my van.
I am used to working with 12v dc,
but these are 70.4 - 91.3 v.
Ideally I'd like to use them as is, for a whole house power supply.
I don't see many inverter/chargers in this voltage??
any recommendations?
IF it is not realistic [easy] to use them for that,
I may consider splitting them.
It looks easy to cut between 11 & 12 to wire for a 36v system.
What bms should I use for that?
Will I need 8 bms?

On a side note,
these have a very high discharge rate available, 6C 560 ah from each cell.
I'm trying to think of what can use that much power that quick,
a hovercraft?? a drag bike?

How much were they if you don't mind me asking.

I may have over paid.
These were $320 for 4 ...$80 each.
I have started cutting these into 14s ... 48 volt packs.
i have ordered bms and mppt charge controllers.
also traded a $2000 car for 30 375 watt mission solar panels.
Now I need to figure out where to put them.
They will take up a LOT of space, if I use them all.
I'm still trying to figure out big inverters

Thank you. Where did you get them, as I am interested in some as well.

This was obviously a 1 time only deal.
I think the original buyer paid over $5000 each for them.
before going bankrupt
