dual/dual cell?!?
 

if i had 4 batts.........2 in series w/2 parrallel to the series batts....2.4v?

could i charge with 3v?

yes, i charge all my dual cells with 3 volts, like namuna sed, not necessary to go much higher than the voltage rating of the battery pack. btw, since you have 2 more in parallel with the first two, it'll take you twice as long to charge

How do i charge my 2 cell bit?

i'm guessing you didn't read my reply....

no you cant effectivly charge 2.4v with 3v.
4.5 will.

the easiest way is to get a single aa holder from radioshack. its a dollar and its easy to install.

that's what i used to think but on my dual cells, i don't notice a difference when i charge at 3 volts or 4.5 volts or 6 volts other than how fast the battery in the car heats up

as soon as it starts to heat up it is done charging.

i usually charge about 3 minutes if i have 150 mah cells, 1 minute if i have 50mah cells
