The pack config and plugs might depend on the build date of the original Bomber. I'm pretty sure the Bombers built around the same time as my Fighter (2011-2013) all used Andersons SB50 for the main discharge and Andersons PP30/45 for the charge connector.
If it's from that era, you shouldn't have any problems just plugging and playing with the original controller and charger.
Apart from that, I would suggest going with more than 10P if possible...although I'm sure your aware of the real world impact of high C rate discharge on 18650's.
As for my pack, today I finished off the final touches and mounted it in my Fighter.
First was a partial bulk charge while monitoring the cells for any drift.
Thankfully I saw no drift more than 20mv.
The wiring harness was a PITA to make, but necessary to let me use my fans and auxiliary temp display via my dash mounted buttons.
I ditched the idea of using 6AWG as it was next to impossible to fit it in an XT150. 8AWG is still more than enough for the 6.5KW max I will run.
After all the padding I added, and the heatshrink around the wire exit, it was a bit of a tight squeeze to get the pack in.
After a bit of massaging and excess heat-shrink trimming, it fits like a glove. Also, what you can't see in this photo is the 2 x 24" Gaadi two end tubes stashed just above the pack where the seat mounts.
With the circuit breaker mounted up in the neck, it's a tight squeeze for all my bits and pieces up there.
I did some test rides around the back yard and managed to pull about 5.5KW with a voltage drop of only 5V which is pretty good IMO.
I do still have one last thing I want to do for this pack though. Because I don't run a BMS, I periodically balance charge after bulk charging. It's always a PITA to open up the side cover to gain access to the balance leads, so I put together an old Parallel cable setup which I will permanently mount up in the neck area. How I will fit it, I have no idea, but I'll make it work.
