Wow, I never thought the Kavan was strong enough, they rate it on their site a 4S 1.20 size or 2S .90 size.
So will a 3 cell Lipo, at 11.1 volts, allow better current for the starter, even at the lower voltage, than say a 12 pack Nicad?
Thanks for help,
The Kavan is geared, it has more than enough torque to start the 170.
I first started experimenting with li-po on starter by combining two 2S 7.4V, 2,100 at the beginning of this year. However, when they are fully charged, voltage can go over 16V. Even though, it has tremendous turning power, and one charge lasted for over a month of continuous usage, I ended up destroying three starters. I have since switched to my current 3S, and I still have more than enough power to turn over the 170.
A fully charged 11.1V li-po is about 12.6V, still way under the allowable rated 14.4V on the starter. I have been using a 12 pack ni-cd on the Kavan for over two years, it has a bit more cranking power than the 11.1V li-po, but you pay the weight penalty. In addition, I have to re-charge it almost every other week with the same usage.
