Supervee battery question-2 batteries

this was more aimed at lenny.
we still havent figured out how your sv is wired… is it wired parallel already? or is it series? can you post some pics of it so we can help you? thanks

my boat is wired series (stock). Was just wondering if I can re wire it to parallel and run on 7.2VDC safely. Without damaging the ESC and motor. Pretty much more time less performance.

7.2VDC Parallel

my boat is wired series (stock). Was just wondering if I can re wire it to parallel and run on 7.2VDC safely. Without damaging the ESC and motor. Pretty much more time less performance.

Jetskier you can certainly safely re-wire your batteries to parallel, again assuming stock 7.2v batteries & motor. Original battereies are 7.2v and motor 14.4v ([email protected] v battereies parallel). If you run the 14.4 motor at 7.2v you will get long run times with decreased speed. I re-wired my SV to parallel as I was going to Lipo batteries and wanted the longer run times allowed using 2 14.4 batteries in parallel.

But if you do that the esc will see a low voltage in the setup I think and go to bump running.
Also you better time your runs or you may pull the voltage on your packs down to far,
And trash them.

A friend of mine want to sell me the battery on the top with the same rating 5000mAh but I notice the wires are only 14 AWG and mine at the bottom have 12 AWG wires. Can I use the one he is selling? Is there a difference in discharge rate?

[lenny]

It just may get hotter a litter faster with the higher gauge,
How much does he want for it ?

[jetskier]

$20.00 he claims only used it a couple of times. First time using a 5000mAh battery, all my other toys are 1600 mAh tops so w
hat is the best or highest charging current to apply?

[lenny]

Have you ever ran lipo cells in your boat yet ?

[jetskier]

no, this is my first boat. it's my Winter Spring project. been running RC trucks for a while, just want to get into RC boat looks like fun.

[lenny]

What do you run in your trucks ?
I was just looking at buying my first buggy,
It's a 1/6 scale at HK.
I never had any real rc cars other than radio shack stuff that I trash picked.

[jetskier]

wow 1/6 is the big boys. I have two 1/16 traxxas mini E-Revo, one 1/16 Traxxas Ken Block drift car, I run a pair of 1600mAh in all on Lipo yet.

[lenny]

Well this is a good time to start,
Boat pull a lot more amps all the time and always have drag from the water in less they get air born.
Liops cells are about 1/2 the price of nimh cells and run a lot cooler,
Also they will make your stuff run a lot better.

[jetskier]

thanks for the advise regarding RC boating. I know all too well about water drag. if I let off the throttle of my ski too fast, it's like pulling the E-brake. 110hp is nothing on the water.

[lenny]

Yep,
I started out with a Rio ep for 75.00 on CL,
And was running nimh cells and doing all kinds of mods to it to get it faster.
Than want to brushless setups and lipos and saw the big pay offs of my mods and work I did.
What ski do you have ?
I have two old 1991 seadoo sp that need a lot of work now.
