I am also on 4s(14.8-16.8v) not 3S
I noticed that. I bumped it up to 6 ms, 3x, 2ms and it still came apart very easily
I would guess your lipo cannot handle the current then.
When I tested with meter it pulls any here from 60-120amps for a couple millisecond on 4sā¦
Which is probably why 40C+ lipos are recommended
It really looks like you donāt have the proper amount of amps. I was running into a similar issue even while running 2 x 3AH 3S 40C Lipos in parallel. I was using a longer wired parallel adapter that was dropping the amps. A single 3S lipo of that size/rating just wouldnāt cut it. I suggest either going with a dual setup with a good adapter in parallel or a higher AH lipo.
Would you recommend this 50C one or two in parallel. I would prefer to get the cheaper option, just wanted to get someone elseās opinion.
I use the 16ah version of this in parallel to make 32ah 4s. But the 10ah is on saleā¦
If your concerned about the C. Most people say 40c for smaller batteries. Ie
3ah* 40c =120a 10ah* 10c = 100a
Or mine 32ah * 10c = 320a
Alright, so I found this 4s thats rated at 50C its 6000mAh which should be roughly 300 A. Do you think this would spot weld 0.15 mm nickel? Or should I just go with two in parallel?
HRB is Bonka cellsā¦
Likely overstated and probably closer to 25Cā¦
Gens ace and itās sub company Tattu are pretty good.
I havenāt tested these but they look promising:
That does look promising. The problem is it wonāt come till next week and I was really trying to get this done this week during my spring break. The difference is that turnigy is 300 A compared to the Gen Ace which is 250 A.
There are lots of promising lipos, but if youāre having trouble why not use the one recommended by the manufacturer?
Oh yeah! I totally forgot he recommended one! I think I am going to go with this one. Since it has a higher C rating than the one he recommends and it will get here Thursday, so I can finish it up this week.
putting two of these in parallel, hope I made the right choice
(2200mah * 40c) * 2 = 352a
wouldnāt that suffice?
or do you mean capacity, for welding time?
I know this means nothing since you guys are running 3sā¦
But I just tried welding with a 4s, 1300mAh 70C pack and it was just fineā¦ Although I could see the pack heating up fast and draining fastā¦
well, i got these batteries almost next to nothing so will give it a try and upgrade if it sucks
