I just got this Hobbico Accu-Cycler (charger)

I was wondering if using a servo y-connecter would it be fine to charge two identical batteries at the same time? I have a pair of 4.8V NiMH 750-mAh batteries that I would like to fly with as a pair.

The charger is made to charge a tx and rx battery at the same time but the tx side of the charger is only good for 6,7, and 8 cells, so that is why i was thinking it would be best to use a y-connector and charge the pair from the rx side which handles 1,4, and 5 cells.

thanks.
