The DP-2170 cases are the 21700 versions of the Polly down-tube shape. Both share a 368 × 95 mm footprint; the 5C is taller (125 mm against 106 mm) to take one more parallel row, so a 36V or 48V pack can be built in either size.
Each case comes with the internal cell holder, a mounting plate, a mechanical lock with two keys and a charge indicator. Retailers sell matching nickel strip sets for the listed layouts as an option.

What voltage can I build?
See the layouts in the model table; the charge gauge voltage must match the pack.
