Pros and Cons

Yeah, 120w is not much, but it can charge 4s at over 8A, so it's not all that bad.

That charger is not much to look at, but the specs seem ok. Price is a bit steep though. I'd almost rather get two smaller but high current chargers. Funny how they don't list a Li cell count, only "49v". That equates to approx 11s. With a 300W limit, the outputs look like this:

Cell  Amps   Limited By 
1s   10.0A   Current Rating   
2s   10.0A   Current Rating   
3s   10.0A   Current Rating   
4s   10.0A   Current Rating   
5s   10.0A   Current Rating   
6s   10.0A   Current Rating   
7s   10.0A   Current Rating   
8s   8.9A    Power Rating   
9s   7.9A    Power Rating   
10s  7.1A    Power Rating   
11s  6.5A    Power Rating

Needs a solid 40A @ 12v to run that thing to full capacity though. :eek:
