When you series all the batteries they discharge at ROUGHLY the same rate. It is good, however, to check the individual battery voltages after a month of two of constant charging/discharging. You will be hard pressed to find a battery with a significantly lower voltage then the batteries in series.
a 48V 1.5 amp charger would charge just as fast as two 2V 1.5 amp chargers. When charging batteries, it is the how fast (amps) the charger can charge that will dictate how fast a specific battery will charge. The only thing that differs between those two chargers is the voltage they charge at. In this case the 48 volt battery charger would make more sense. You will be plugging in on plug instead of two, minimizing accidents.
Yeah the charger might work. I think there is a general rule when charging SLA, you should look that up.
The battery's will always be higher then their specific voltage hot off the charger, that is normal. There is no constant battery voltage when discharging/ charging battery's.
Wy go with SLA when you can get lipo with just a little bit more money, and the battery's will last three times longer then SLA. Not only that they are a good three times lighter as well.
I got this charger http://epbuddy.com/index.php?main_page= ... cts_id=170
and four of these batteries http://www.hobbyking.com/hobbyking/stor ... se%5F.html
and I got a charge/ discharge harness from icecube, GREAT GUY! =D

If it didn't kill you, it just built your character.
You know your bike is powerful when even you, the builder, can't control it.
