On the 20700B you can only get 15A on each cell for a total of 60A on a 12S4P form, discharge is too low for a Carver deck with pneumatics from my point of view. I rather use a 12s4p made of Samsung 30Q 18650 or even Sony VTC6 instead for 80A discharge.
If range is very important to you a better choice would be a NCR20700A, that on a 12S4P array will give you a craxy 120A of discharge, that’d be EPIC!
The enclosue is able to hold more than 60 18650 cells, however a 12S6P would be perfect if want to run a full size BMS even the BIG ones plus two FocBoxes.
If you want to go crazy and need extremely long range you could fit a 10S8P, completely unnecesary for everyday use but there are a lot of insane guys around here so they might find this a pretty nice starting point.
At the bottom I left a flat surface in order to allow an ESC aluminum heatsink fitment.
From your previous post, seems that you didn’t ride with the new enclosure yet. Would love to see if the motor mount and motor make contact with the enclosure while carving. Also how many 20700 cells would it be able to fit?
Yes, it’s definitely more compact than the spud, way narrower, looks sleek. The enclosure may have a double stack enclosure otherwise you won’t be able to mount anything larger than a 10s2p, I’d love this deck with a 12s3p, a 12s2p made of ncr20700a would be ideal for 60A discharge and two focboxes.
