I can see what you are saying about Lipo, but I can't see it. As last year with cells, I was getting 10+ minutes practice at a time (til dumped) and some times I had Chazz waiting with another car so I was on for 20+ minutes or perhaps 30mins at a time!! mental.
This year I have Lipo, but I don't want to run these flat as it damages them, so I will time each run to be exactly 10 minutes, so I won't be running til dumped. And I won't be staying on for two runs, as having 1 Lipo pack per car mean I won't have a lot of cells charged at once to keep going up like last year - got to keep going back to charge them.
Proof is in the pudding, we'll only find out on Friday how busy practice will be.
I'll try and cain it Thursday so I can be sensible on Friday an not hog a spot on the rostrum.
