Anyone else think swordfish

[Engelkefarm]

Swordfish 200a swelling batts and running hot. Leopard4084 x445 2 3s packs. My seaking 180 never did this. Anyone having same issue. Boat is a genesis

what batteries are you using? I dont exactly care for sf esc's but there not a whole lot of affordable choices out there. seems lately they are hit and miss.

FYI, when your batteries puff, it is usually because you drained them down too far, and it doesn't typically puff until a few cycles later. The damage to the batteries likely happened well before they started showing it. I really doubt it's the ESC causing it, you most likely ran them a bit too long a few runs before, and this set of packs is probably past the point of no return. A pair of 3s/5000mah packs is working pretty hard to supply a 1600kv 4082, you prob wouldn't get much more than 3 min without running them too low. I have a couple SF ESC's, some I have had a few problems with, some have been great all along. When I did have problems, the owner of OSE was very helpful, but I have also sent them in directly so as not to bother him.
Considering that you just dragged up(spammed) 3 other threads in less than 10 min to post that SF ESC's "are crap" and complaining that the owner of OSE won't help you, then started this thread to say the same, when it is perfectly likely the ESC didn't cause the problem in the first place, I wouldn't blame anyone for not jumping to help you anyway. In the few years I've been doing this, and the several years of threads I have read through, I have not come across on incident where an ESC caused batteries to puff. Once in a great while it's a quality issue/bad cell, but prob 95% of the time it's because they were run too hard for too long.

I was able to get a 3rd place in Q-Sport Hydro running this esc in the 1st 2 heats. The second 2 heats I switched out to a SF240 that could take the heat better.

Before bashing Swordfish in every thread, maybe get to the bottom of your problem. It sounds like your having other issues.

A few fast boats with Swordfish controllers...

Turnigy 2 3s 5000 mah 65- brand new out of the box. Also two brand new atomic 5000 35c those will swell a bit sometimes 8 mm bullets 3.3 lvc. Batteries will drain uneven also. Ran boat all last year no issues at all. The past two weeks smoked a 240a swordfish thats in china now and something is up with the 200A.

Im thinking its a resistance problem creating the heat. I have the data logger for it i dont know how to post a picture but can send it in a email if someone else wants to. Even with a x442 it will do the same. Motors cool. Esc says 70-80cel. Batteries are smoking. Timing is at 12*

[Rocstar]

A motor that is going bad will take out an ESC. Possible something is up with your Leopard.

[kevinpratt823]

Many say that Turnigy is crap. They are hit or miss, as in some work great out of the box but there is a high rate of failure/bad cells also. The a tomics are just plain rated too low. If you're running a 6s1p setup with that motor you really need higher c rayed packs if you expect them to last, 3-5can@5000man is only 175 amps, and you are likely pulling that. Considering most c ratings are bogus and overrated you're not really within the limits so I would expect those packs to fail. Batteries draining uneven has absolutely nothing to do with an esc, it is a problem with the packs, connections, or perhaps the motor as Rocstar said.

So you've smoked one controller and "something" is up with the other.... and your packs are swelling? Just the Atomic packs or the Turnigy ones as well? What's your motor KV BTW?

[Engelkefarm]

It seems like one batt will be 9.xx volt and another will be like 11. I pull it in when it hits lvc. Lvc set to highest 3.3v. Its a 1600 kv motor. Motor spins like always by hand stops pretty well at each pole

[Engelkefarm]

But my seaking 180 ran flawless. Guys last time i checked i live in america if i want to say some chinese trash is junk i will. Im helping other suckers avoid my problems. The only difference is i was using 5.5 bullets last year now using 8mm

[Engelkefarm]

No binding in drive. Greesed everytime.

[kevinpratt823]

Most experienced boaters would tell you not to run to LVC, and by experienced I mean those of us who have learned by ruining many batteries lol. You really need to time your runs, and stop before they get that low. The voltage comes back up when they rest for a bit, and the esc only knows the total voltage, so if one pack is dropping quicker, it goes well below the lvc/cell setting because the other is fooling the controller. Also, consider that the C rating really only applies IMO to fully charged packs, if you try to pull that kind of current from a pack that's getting close to 3.3, it is heavily stressed. If one of the 2 packs is compromised, the other will fail soon as well, because it's trying to pick up all the slack.

[Engelkefarm]

Turnigy packs are just fine i agree atomics are not the best
