Interesting... I read this as I had taken what I was told as correct.. I've took a look on the Trackpower site and they state that their LIPO's ship with 70% charge. Quote 'When you buy a new TrakPower pack it comes around 70% charged. The pack can be charged from new at the normal charge rates' so as you suggested 40 - 50% I thought i'd do a little digging. Kokam are supposed to be one of the best quality cells (Or so we are told by Orion and the likes) so I looked up a couple of their technical data sheets. Kokam quote '
On a storage, Cell state is 40%~50% charge(3.7~3.9V).' So CHB does seem to have a good valid point, I still maintain that I have had no issues however, but then - Time will tell..

Bantam BC6 is great for that indeed ! (it's not the only one that has a storage mode with ~50% charge) |
