LiPo Charger - Rates & Cutoffs?

[djmcnz]

Hi,

I've got the common Intellect 4200 2S 30c saddle packs and currently balance charge at 4.2A. The packs don't get above room temp.

Am thinking of the following settings:

Balance Charge: 4.2A (1C)
Fast Balance Charge: 6.3A (1.5C)

It seems that good quality packs can now charge at 2C. Anybody have experience with this? Thoughts on my fast charge setting?

I've set the charger safety cutoffs to:

4.3v/8.6v
4500mah
40c degrees

Are the v and mah cutoffs okay?

What should I discharge the packs to 3.2v at (assuming I need to)? The full 10 amps of the charger? They're reported as 30c cells.

Thanks in anticipation!
