How many mili amps, (like a 3600 battery) can a supervee 27 have. i have a 3600 and it died and i need new ones. what is the biggest i can put in the boat with a stock motor?

There's really no limit. It would be limited to how much weight and space the batts take up.

If you are asking about NIMH batts then they are up to about 5000-5300 mah in the same subC sized cells now.

I have a 3600. it doesnt say what it is. like mili amps.

The bigger, the better. The boat has room for the biggest made.

toklat,

3600 is what your mili amp is.
have a look at the esc, the esc will determine how much power you can use, however,
I don't see any problem going from 3600 NimH to 4800 or 5200 NimH.

size and weight and room will dictate.

Dan.

ok. i remember reading somewhere that the supervee can go up to a 3800. but i couldnt find it again. the 5200 is the same size as the 3600. so i hope the boat can handle it.

The Aquacraft site shows that you can use a NiMH 7.2 volts (6cell) stick pack from 3000 to 5000.

the site also says that the recommended product was the best choice at the time the product was released.
I believe you can also use the NiMH 8.4 volt (7cell) 5000, but don't quote me on that one.

if you later want to use lipo instead of NiMH, you need to upgrade the ESC to a minimum of this one: http://www3.towerhobbies.com/cgi-bin...?&I=LXVSV4&P=V

I just finished building an SV (not the "R") for a friend and with a low voltage cutoff there is no problem using lipo's just watch your propping and temps. I added another water pickup so the esc is independant of the motor.
It goes pretty good with 2s 5000mah 40c batteries and a GR 40-52/3 prop.

alright thanks guys. i will order me up some 5000 lipo and switch it out. thanks.

Hey guys I"am just switching to lipos also 5000's Can you please tell me what kind of cut off switch you put in and where you got it from.It's going in a sv with separate water pick up's

Tombsy

The LVC I've been using is the Dimension LipoShieldIntelligent Lithium Cutoff, 1-12s, Soft cutoff.
I get them from Kintec Racing they have been reprogramed to cutoff at 3.3v per cell, usually they are set to 3.2v.
Lots of fun stuff at Kintec for your SV.

Thanks for the info

I went to the Kintec site and ordered the cut off along with a few more items, and I,am not sure about how to wire it in.I was going to wait untill I got it and went over the instructions but I do'nt want to lose the contact with you. So if I have any more questions can I get a hold of you?
Thanks Gary

Absolutely, the cut off is easy the two wires connect brown to black and red to red. Use some new heat shrink and solder them in at the battery plugs.
The esc plugs into the cut off and the cut off plugs into the receiver.
Here's a link

Thanks again- I think what had me was that they did not show the other battery plug and I didn't think it would work just hooked into the one.

Tombsy

I maybe confused you as well, it's the red on one plug and the black on the other.
Well I finally changed my connectors to 5.5mm bullets on 8 packs and the UL-1, the deans just looked too crappy on the giant wires of the Turnigy packs and they come with the bullets anyway.
Thank god for butane soldering irons.
I made some plug covers but I'll just have to be more careful of shorts.
The Grimracer 40/52 3 blade worked pretty well on my friends SV.
