What length are the battery tubes supposed to be?


I have a long length of battery tubing, but I can't find the dimension for how long I am supposed to cut the battery tubes. How long are they supposed to be? Thanks a bunch!


Hey Evan,

Thanks for pointing that out! The current CAD file for the ROV has the battery tubes as being 210mm long, however I'll probably update this to 215mm for each tube since the three lithium batteries we now recommend (instead of for standard C-cells) are slightly longer.



The new battery tube length for three Trustfire 26650 batteries with a protection board (or LiFePO4 batteries with a length extender) is 233mm.
