Hold on a second... Is this true, or is something else going on? I've never heard such a thing.
In fact, I just went through my first email exchanges with Ping (11/08):
...Thanks Ping. I have two more questions:
1. How much should I drain the battery the first 5 times? only 75%?
2. Is it okay to leave the battery in - 0 degrees celcius temperatures?
Thanks,
Greg
Hi Greg,
1, Just use the battery how you want it to be. LiFePO4 doesn't have memory effect. So, it doesn't matter.
2, Yes, you can leave it in the temperatures. But its performance will be reduced much. On the other hand, the low temperatures are good for storing batteries. But please pay attention do not take the pack from low temperature to higher fast, that will produce water over the pack.
Best regards,
Ping
I'm very interested because my Ping pack has been sitting out in the garage all winter, and the last times I've tried to test it, I'm pretty sure the BMS was cutting out...
