i have a SV27, Right now i am running 2 DTX 3800, i got them when i got the boat a year and a half ageo, though they have not been used much, i finally got the stupid boat working only a week ageo, but i need another battery pack just so i can have a longer run time and swich packs after one runs out, towerhobbies has some DTX 4600's 6 cell that look nice. (The boat is already quick enough for me, so i dont really have any reason to spend alot of money on lipo's and a charger for them)


I have two questions though, what will i gain out of the extra Mah, run time, or speed, or less heat build up?

Also would it be safe to just get two 7 cell 4600's? I dont want to mess up my ESC.


BTW i am running with a x642 prop

Thanks

Edit: i made some elite 4000's on cheap battery packs with upgraded soldering and they are only 46$ a pack which is cheaper, how do the DTX cells compare to the elite cells?

If you are satisfied with the speed you are achieving currently, why increase to 7 cell packs?

You may as well just go LiPo to save yourself money in the long run and headaches.

Increasing mAh should reduce heat and increase run time and / or performance. This is very true with LiPo but not always true with NiMh.

I would just want to upgrade the 7 cell if it would increase my run time or lower the heat, but i dont want to risk burning up the ESC

Only if you greatly reduced prop size which would just counter everything. In my opinion I was never happy with 7 cells vs 6 for the SV.

Thanks for the info man, i am just going to make a 6 cell Elite 5000 SC pack with upgraded solder and deans ultra plugs, that is not to much for the ESC or anything is it?

Your ESC is only limited by current and voltage. Cells only determine the amount of voltage and you will be safe at 14.4v.
