Urgent battery question... (200mah)
 
OK, so I just finished soldering (2) 200mah batteries in series, and I wired them up, and modified the controller(ran wires straight from the battery pack to the charging base). My questions now is, how long should I charge the (2) 200mah batteries? I charged them for what I believe to be about 2 minutes, but it was performing near stock. Is there perhaps a formulae you could direct me too to calculate my charing time?

Urgent...

No meaning left in the word anymore? :(

You will need more than two AA batteries to cahrge a dual cell. You can pick up a 4 cell AA box at radio shack and use that as a charger.

With the controller hardwired, it should be giving the charging base 3V. My Bit only requires 2.4V for the batteries. A standard controller would be fine to charge with.

Next!(no offense)

2xAA Alkalines put out ~2amps, per minute that's (2000 / 60) = 33mA.

So to fully charge that 200mAH pack, I'd suggest a charge of 7 minutes...And I'd also STRONGLY suggest monitoring the heat while charging, a charge rate of 2A for several minutes like that is NO JOKE.

Good luck.
