Has Anyone ever used these watercooled battery coolers

[kevinpratt823]

The guy from Tunder Power was actually steering me away from going paralell 6s instead of series 3s of a higher mah. His response more specifically was related to what happens when you stack a lot of cells, I don't want to discredit him.

And what happens when you stack ALOT of cells? Other than more weight...

[Doby]

The pack gets higher???

He was implying that they overheat easier, and there is less room for the cells to expand, also the resistance is greater the more you link together. I also mentioned going with 2 seperate 3 cells in series for 6s on each side, then paralelled, but then he said that the extra wiring between them would give more resistance, as opposed to the factory links in a pack. I'm beginning to think I should take the whole conversation with a grain of salt, and do what gives me the best results through experience and my own knowledge and understanding of electrical theory, which has been my bread and butter for well over 20yrs.

I'm sure you probably know more than the guy you were talking to. LOL For those that don't know, when you parallel packs is your batteries work half as hard. So they run cooler and last longer with less chance of puffing. Also your ESC will be less subject to ripple current. With the power we are putting in boats today, the extra weight isnt much of a disadvantage. As a matter of fact, allot of boats would probably run better with some extra mass. Your run times will be longer so watch the motor/esc heat.

Be as it may I plan to use them for bling and cooling. Doubt my boat will fail to run because of them. I don't race so hey to each his own.

How will you get the cooling plate to effectively cool each cell in the pack? Run the packs on its side? I you run them laying down normal, the plate will cool one cell more than the others no?

Kevin, I think you are much smarter, and probably know something sounds weird about what this guy is telling you. If a parallel setup can provide more amps, is it not less likely to heat up? And if so, would the cells need "room" to expand?
Bottom line is, in FE boating, we all realize the parallel setups run cooler because they aren't working as hard. Go with your gut man, sounds like its giving you better advise than tp

[TheShaughnessy]

I say run them for bling since you already have them but don't hook up the water lines.

for the few $ cost from HC, these come with absolutely great water nipples !!!
5mm x 15mm long, sturdy and stronger than the usual arrow head jobs..
That couple $$ is well spent !

Sorry if I steered this thread off topic, but it is some good discussion. FWI, I'm pretty sure my 3s 6600mah packs are the same makeup as the 6s 3300mah packs, the cells ar just linked together differently inside the packs. They are basically physically the same size, and the (2) 3s 6600's in series is basically the same setup as (2) 6s 3300's in paralell as far as output, theoretically.
