Looking for recommendations for a LiPo to replace my Pb battery in my Ofna Blue starter box. Checked out Amain and found the ProTek 4S LiPo 20c pack. Will this be good?

Id stay with a 3 cell what was the voltage of ur old pb?. 12.. so 3 cell will work. Id go with LiFE as in the A123 cells ..sure they are harder to solder but there are cell holders out less maintenance is always a + for me.

This is my current setup. Also w/ the new consensus that most folks are using LiPo's for starter boxes that there would be a LiPo voltage cutoff switch available for safety reasons!!

3 cell lipo would be best stay at 12.6v a pb can be as high as 14.4..

4S works w/o any issues, a 2 cell NiMh pack also has 14.5v normal voltage but when just chargerd it can also be over 16v
