Not including rising or chucking the whole efoil in a bucket and running it
I’ve got a discharger that does up to 8s for drones but what can I use for higher voltages is there a plan available online for one I could make or does anyone sell one?
I sketched up a load bank with 12V light bulbs for the same reason. A group of 4 in series and a number of parallels to your wanted power would do the trick. A 400w 12s discharger would be roughly 8€ with just the bulbs, double with sockets.
If you’re wanting a higher power output then you could do a roll of copper winding wire in a bucket of water but too messy for me.

That’s how we do it too

You can also use the Motor to discharge, metr has this option. It uses the windings of the motor. Might take some time though, as the motor needs to dissipate the heat. You can find the option under „expert/discharge“

I’m using 10 high load resistors in parallel,
Drawing around 200W consistently
Another easy option is 110V hairdryer, also uses 200-300W on 50V.

Why do you need to discharge batteries? Only for storing at around 50%?
Exactly, for storage before winter. Or to cycle them once or so if not in use for several months.
If I fully charged them to 4,2v per cell and turns out that I can’t use them, I discharge them for safety purpose to 4,0v.

When something breaks and your battery is full… over a longer Ebuild streak it’ll happen a few times.

Icharger x12 has a discharge function up to 12s.
I connect my battery to a cermic thermal heater (lightbulb style) and let drain out for most of a day
I wrapped some nichrome wire around a piece of plywood & attached some 48v computer fans (essentially a 48v heater). V=IR and P=IV is the only math required. Nichrome wire available on Amazon
