Default GP3300 Cutoff

What mv for a pack does everyone set the cutoff at, ive heard 30mv/pack but also 15mv/pack, I was sure 30 was about right, what is the opinion.

What charger are you using? Cutoff often depends on the charger, as some use 2mv up to 6mv.

I usually don't get involved in these discussions because people tend to want a cold hard "0.02 volt peak detect" type answer but I always set peak detect based on temperature of the pack. I always want my cells to peak at 135 degrees whether they are GP3300s, GP3700s or IB3800s. This means my peak detect will vary from say 0.01-0.05 depending on the ambient temperature of the room I'm charging in and the rate Iím charging at. In other words, in the summer, my peak detect may be 0.01 but in the winter, I'm up around 0.05. It's almost a necessity to have a temp gauge on hand for electric racing these days. You can get decent infrared ones for around $30. I may catch flack from other battery companies, but that's what I do and recommend to all my customers...
