Seaking Boat ESC recalled by factory

[sailr]

I got different information from Jack's assistant than I did from Jack in two different emails. Please don't make me the bad guy here. I'm trying to help. Jack's the boss and I believe he knows more about what is going on.

OK, so "Benson" has his Seaking esc's on ebay listed as version 2.0. It says nowhere what 2.0 means. I wonder if he's hoping people will assume that it's the upgraded version

the seaking one i had was supposedly v2 but lasted all of 90 seconds

We're in the same boat. I have a brand new one in the box too. Bought it about a month ago off ebay. I can't buy direct from the factory unless I buy 50 pieces. All other dealers are required to buy 200 pieces to get the best price. I'm not trying to boast, but the owner and I are friends. The Chinese value friendship more than the business deal.

Actually most reports of the 180A are good. One of my friends has one and it has held up perfectly. I know the owner is a very particular guy and if there is any possibility of a problem, he will eat the loss and fix it. Hopefully most of them are alright. I do suspect the newer ones will be better in some way.

Thanks for the encouraging words Sailr,i do hope you are right now

So far mine work fine,'touching lots of wood'....

I purchased my SeaKing 120 from hiModel about a month ago. I didnt pay very much for it so it's going in the boat. If it flames, it flames. I'll just replace it with another higher quality ESC and hope for the best.

V2.0 is the ones that were recalled.

ESC's in boats? do the fly guys and car racers have the problems we do. I think not...I have never used them but that well known expensive German manufaturer has a pretty stellar reputation along with ETTI on the economy side.
Jim, your honest posts are truly valued

Douggie,
I fly also. Yes, we flyers face the same issues. We do let the smoke out for the same reasons as boaters by overpropping, not providing enough cooling, running too many cells and the BEC at the same time, etc. But generally it is rare.

Boats subject the escs to totally different conditions. The esc must adjust instantly to heavy load vs. no load, that dreaded enemy, water, etc. ESC's work a LOT harder in boats than planes and have a lot more opportunties to smoke.

While those mega dollar German controllers are good as well as the ETTI, I have still seen them smoke. There's no such thing as a perfect esc at any price unfortunately. We just have to try to find the ones that more consistently perform well.

I can't speak for the car guys but generally their motors are geared way down so they don't present the same "shock" to the motor and esc as in boats. They also run out in the open so cooling is more efficient in my opinion.

Went the Kontronic Jazz route after that,still going strong on 9S after about 2 yrs,suberb escs.

The will be a new Brand / type of ESC coming out of AUS very soon, i posted this info in the members info section, but it must not have been approved, Here it is again,

I know a guy who is in the final stages of completing 2 esc's and LV200amp and a HV 220 amp one.

Features: Thermal shutdown that actually works
3rd chanel Timing ajustment on the fly
Fully water proof ( thats the sticking point at the moment.
Water Cooled.
Fraction of the cost of the HYDRA

Cant say too much more they are watching me.. i will try and keep you posted.

You can run, but you cannot hide, John

Loose lips sink ships, mate.

ps it is waterproof.. idiot proofing takes longer.

Bugger they have found me. Will have to go under ground for a while.

Seaking 90A ESC

I bought a Seaking 90a about 3 weeks ago and I am having a problem with the low voltage cut off. I wanted to know if anyone else is having this problem? When I am driving my Rigger for about 2-3mins, the LVC activates and the battery isn't even fully drained, and when I go to check the voltage it says 4.0v a cell, and I have it set to 3.0v a cell. So I have ordered a Novak Smart Stop 3-cell and hopefully that will work. I have tried to contact the seller on ebay but he won't respond to anything I ask.

Thanks, Chris

[drwayne]

dont use auto cell count
I have the same fault with my own esc.

[TRXRUSTLER]

Seaking 90A ESC

I don't use Auto cell count I specifically set it to a 3s lipo and 3.0v a LVC, and it still cuts off at 4.0v a cell.

[drwayne]

umm
card option 2(3) for 3cells
3(3) for 3.0 ( I consider that low for a LiPo... )

havr you logged a run?
the esc will trip at 3.0v cell if the total v = 12 ( doh ! )
but underload some older/weaker/used/abused cells will decay to a lower voltage than a rested cell will display.
ergo run till trip.. and read logs.. probably shows much lower than later when pack cooled.
