Hi Gonzalo38
Don't worry about your P160SX. I'm using std. harness and batteries with my other kerostart JetCats.

P180 + P200 are using another bigger starter and the enginmass to turn, is much higher than the rest of the JC line. Therefore in conjunction with kerostart electric power demand is much higher with these two engines. It seems we have to be careful in selecting batterypacks and considering wire gague.
