Nice! but was 55-110A enough for jumping really? What gauge wire did you use?
Really line them up to get that maximum impact

Keep it outta sight of Highway Patrol 
Sjeez, John McClane would be jealous to that one...
Are you planning on a Die-Hard 2022 remake?
But no BMS? For jumpstarting I get it (if those cells are capable of providing sufficient power)
But a. many of those are 'only' 2C, thus like 110A max or so? (And jumpstarting requires more)
and b. for the other purposes you really want a BMS imho or you will eventually discharge the cells way too low.

Most cars just need more voltage to get the starter running and these are rated at 165 amp max but there isn't a reading for peak amps. Will use to help jump start my backhoe in the spring and will see if it works on something that large.
The bomb look was by mistake but I like it.....
Wire is 2 awg.

I used the 25ah Navitas cells from BH in a 4s configuration to jump my V8 4Runner below freezing, the car pulls over 500a on initial contact. I don't think that's great for the cells though, but to be fair, I still use that pack and they perform fine.Yes they are 55ah.....SAB 60280 cells that batter hookup sold for a while but can still be found on ebay.

If you'd like to trade, we could definitely meet at a local airport. ?

If the 4 banger doesn't work I got 4 of these packs that are 4p5s at 16 volts...
I built it this way to power my 90's high school Mustang with a 351 that my son and I are redoing....
I put the 4 large packs in series with my hybrid inverter to backup power the house at 68 volts 220ah 15kwh.... That is in parallel with a 280ah pack and 50ah battleborns....for total 550ah and 35kwh...
