k if 10awg should be fine i will sue that
only hard bit is soldering it into a xt90
thanks a lot
What does corrosion look like from these aggressive fluxes? Do the wire strands look powdery whitish?
I use a tiny blob of hot glue at each end of the cells on both sides, just to hold the groups together while I silicone them.
If iām really in a hurry, i can hot glue, silicone, wrap in fishpaper and begin welding before the silicone has set cos the little blobs of hotglue hold it well enough to work with.
I agree that it is super corrosive (and aggressive) and definitely needs to be thoroughly cleaned.
In certain situations it can work literal magic though.
Iāve had a couple cells show some slight rust under the shrinkwrap due to exposure to it (soldered pack). Iāve been keeping a close eye on it, and after the initial rust appearing it seems to have stopped getting any worse.
Thatās a good idea, I tried my hand with hot glue yesterday did do a great job and this morning I tried separating the cells and it was really easy to do it. Plus the hot glue came off leaving the cells really clean.
Also, I went shopping for some silicon and canāt find neutral cure silicon, they only have bathroom type, woodworking type or mastic glue.
Thanks. Iāll look for this locally, meanwhile any other brand/product to look for? Anyone? In case I canāt find this
One thing you can do is check the warnings. They all have something like āthis product gives off X and Y chemicals as it cures, avoid breathing blah blah blahā.
If the chemicals it gives off include acetic acid, itās an acid cure silicone.
If theyāre something like ammonia and methanol, then itās a neutral cure silicone.
Oh man thatās really helpful, thanks Iāll look for the composition next time i go to the store
If it smells like vinegar, itās the wrong stuff.
They have a really serious āif you open it you pay for itā policy at these stores
After you open one, if it smells like vinegar, then pay for it and use it to seal your homeās gutters.
Hy Guys i got a question regarding a Battery i wanna build.
So i want to make a 16s4P battery with 21700 molicell cells => the battery will give me 180A total
for the esc i think ill go with the Ubox and for the motors ill go with 140kv APS 8085s
So the max motor amp is 125A and the esc can provide 100A to each motor.
Ad the battery is the bottle neck in this scenario i want to ask you guys if this setup will harm the battery pack in someway as its always on its limits when i set the motor amps to 90 for each motor.
Should i go for 16s5P instead?
KR and thx very much!!
I mean if you keep doing it youāll reduce the lifespan and capacity of the cells, Iād aim for 6p actually since P42A is only really good for 35A (you want Samsung 30T if you want serious amps)
This is a literal truck load of power, unless you weigh 300lbs youāre going to struggle to maintain amps this high for even a second.
Also battery A doesnāt equal motor A. You have two different voltageās in and out, itās not just direct current through the ESC, so you could run 50A battery and 100A motor, and it would still kinda work. 25% is an acceptable difference between the motor and battery amps.
What you mean with the pa42 is only good for 35a??
Mooch did some testing with it, the cell is overrated
Each cell is really only good for 35a, 35x4 = 140a max capability.
This made me lol a little, true its overrated, but dang 35a is a ton
hahah ya āONLY 35Aā
