I used the tough plastic pipe hanger strips from Home Depot to hold the battery weight in place by threading a bolt through the top of the deck, through a pipe hangar hole on the bottom and then using wing nut over a washer to loosen/tighten the strap for getting the battery in and out.
My mower uses a nice set of spring clips to hold the pack in place when dropped in. That would be a cool system that’s pretty vibration resistant but I’m sure it could get loose over time, especially on a board. Probably fine for a bike though.
Thank you much for the link, that is helpful in seeing what pins out where. I will likely order one for science.
Adding to this thread since every time I try to google for information about these tool batteries I struggle to find any information besides 100 videos of people trying to jump start dead ones back to life no (some very bad ideas out there)
My latest acquisition was a Ryobi 40V 6Ah battery with the proper adapters from Terrafirma.
After my first ride to try and figure out the range I rode it down until it had 1 of the 4 battery level indicator lights flashing.
At that point it read 15V across the tool +/- terminals which would be very bad for just a raw 10S battery output (1.5V per cell!)
I put it on the charger for a few minutes and it popped right back up to 34V with 2 (of 4) lights on for battery level. I’m not taking the battery apart to find out but it seems like the “15V output” was some kind of protection mode from the internal BMS.
Was using this on a mountain board with flipsky dual FSESC and the board just gradually slowed down until I got back to my car which was actually a pretty graceful way for it to die.
