Charging 10s A123 cells w/ 2 chargers

I am making several 10s A123 packs that I need to charge and balance with 2 5s charger/balancers. Can I hook up the chargers as shown in the diagram below (using the common between the 5th and 65th cell. Or, do I have to actually make the pack 2 5s packs for charging and then connect them is series later to make 10s.
I did not show balance connections to simplfy the drawing.

You can IF you use two separate ISOLATED from each other power supplies.

If you can't guarantee that, then you would need to have the pack as 2 separate 5s packs for charging.

Thank you for the information. I will not be using isolated power supplies, so I will seperate the pack into 2 5s packs and charge that way.

be sure to cut the ground wire off the power supplies as well ( where it plugs into the wall), this will also be a common point and things will smoke if ya don't.

Ok, then will this work. I could use a shorting plug between cell 5 and 6 to create a 10s pack for flying. I would remove the plug and connect as shown for charging. That would amount to charging 2 5s packs.
I would be using a single power supply for both chargers.

If you haven't already bought your chargers, you might consider this . I have one and it works great for up to 13s A123 packs. I charge my 10s2p packs in 20 minutes and can charge faster if in a hurry.

Later;
