Description
Pretty self explanatory
Battery case for 30x 18650's
Sized to fit a Raleigh twenty seat tube but I'm sure it will fit others
Cutouts in the top for battery gauge , switch , charger port.
Was a very tight fit once I added the wires and BMS so take extra care of your wire routing when building your battery and you should be fine
Holes will need tapping , I find tapping partway them letting the bolt create its own threads (VERY carefully) gives a very strong fixing.
