Should have included this in the 1st post.
The LiPo were straight from overnight in garage to car boot, 2 hour journey to venue so would have been @ near ambient temp and into the hall. Installed in car and used. So after 1st two runs I would guess they would be at a decent working temp all day as I used only one pack.
Ran a single pack all day yesterday @ Batley on a 7.5bl geared 26/78 for a a B4 gearbox putting in cira 1200mah after a run. We had 8 heats so cells were used in a race, rested for 6 or 7 mins whilst marshalling then back on charge.
I have a pack that I charged for Worksop that I will try and get graphed via a Pro-Trak to see how a precharged pack perfrom over a warmed pack. I'll use the same pack for the testing using an 8 heat simulation. Back tonight with data hopefully.
