You got it sir. Unfortunately, this is somewhat of a mixed bag. My 60C batteries do indeed have a steeper temperature coefficient slope and will outperform my 25C lipolys at high temperature. Sadly, the temperature required to reap the benefit of the steep slope is also at a place that it's starting to cause damage to the cells.

The ideal lipoly will be one that has low IR at normal starting temps (70-80F), and contain the magic elixir that provides the steep slope. That would suit all modelers and may be able to survive harsh continuous discharge rates above 40C with little damage. I will broadcast quite loudly if I ever come across a lipoly with these characteristic.

Cheers,
Mark
