You gotta be more specific than that

like the wires breaking on the sensor

like in the middle of the wire 3 wires are broken in half.

If it’s not inside the motor and it’s the only problem, then yes, it’s fixable.

just solder the wires back together?

Solder and insulate the wires with heatshrink or similar. Adding tape and/or something to protect against what broke it the first time are also strongly advised

it’s a good idea to add nylon sheath and some glue heatshrink to protect the sensor bundles too.

Can anyone confirm if Sealey High Strength Stud-Lock is any good for esk8? I have some from a previous project so though i’d check before buying loctite as you need a couple strengths for the motors / mounts and axels

I don’t use adhesives on axles and don’t recommend it, but for everything else you can get by with only Loctite 290.

Use Red Loctite for everything* imo

A lot for permanent stuff

A tiny lil drop for things you may need to disassemble in the future

*And ONLY 648 to adhere a motor pinion to the shaft on boardnamics gear drives

Okay !
Thanks

I use 638 on all my shafts. Fight me

I hear that’s good too, but I have no personal experience with it

Pfft, what kind of fight is that :unamused:

Seems its like most things in DIY - a lot down to individual preference / what is at hand

Looked through

but recommends 3 different types, guess the sealey one is not suitable so will have a look at 290 & 263

I have a 12s4p battery made with 30q and charged with through a daly bms that is approaching 2 calendar years old but has been barely used. I estimate it was fully discharged about 3 times total over that time period because it was a battery for a build I took apart pretty quickly. I stored it at around 60% when I wasn’t using it. I built a new board out of spare parts recently and realized it won’t charge past 48.1 volts.

I am looking for general advice on what to do with this thing, must be a couple bad cells in this thing right? Worth it to seek someone out to try and repair it? I should definitely not use it anymore regardless?

Measure the voltage of all the p groups to get a better idea of what’s going on inside the pack. You can use a voltmeter on the balance leads.

just make sure not to short any of them because they are very close to each other

Anybody who’s fucked around with tool batteries got guesses as to what the resistance and c are doing? C maybe continuity? Ohms symbol is resistance so maybe a thermistor?

Oh dude these things are so annoying

I couldn’t even figure out how to manually charge my ryobi ones, there’s a different voltage across the C, don’t know exactly how it works but there is some kind of check that happens before it’s allowed to charge. The BMS won’t even let the battery charge if you just hook up to pos and neg
