i am looking to assemble my own charger, i have a circuit in mind. for a 2 cell 3200mah. i know that the nominal voltage of a 2 cell lipo is 7.4v. 1C would be 3200mah. so is the charging voltage something just a little higher than the nominal voltage? or is that as much of a concern as not going higher than the 1c rate?

the charger would be mainly for maintaining the cell, maybe around 1/10C to 1/5C for mah. a safe low current charging.

what would be a good voltage range for the charging voltage? between 7.4-10v?

actually it is a solar type charger i have in mind. i'll combine the cells to meet the needed volts and the needed mah.

when i can, i'll use my standard lipo charger for a peak charge.

any ideas?
