Need advice in Charging a123

[mothman]

I just bought 2x 2s2p a123 cells and Im not sure what charger should I use to charge these batteries. Actually I already have this charger I bought this charger a couple of years back and never have the chance to use it. So Im not too sure how this changer works. lol.. So I was wondering if this charger can be used to charge the a123 cells. There is also someone who is selling a hypersonic charger. But from the spec I can see that it can only charge 1-3 cells. However if this hypersonic charger is the best for a123, then I dont mind charging the battery one at a time. So what do you guys think? Really need some advice here. Any advice, opinion is greatly appreciated.

Thanks
