If you are talking about the Orion 4800 packs that come encased in the plastic, I believe that they require some sort of proprietary balacing harness. The LBA10 won't work unless you come up with some sort of adapter that will allow you to access the individual cells.

Orion says that you really don't need to balance their packs. I don't buy it, but it's what they say.

You might want to look into the trakpower v-balancer (I think it's called). From the pictures I've seen, it appears to use a similar "socket" for balancing.

The next time you buy packs, look into the trakpowers, if that plastic case thing is what you like. The orions are, as you posted, in a 2P configuration and are only rated to 15C. The trakpowers are of a 1P configuration and are rated to 20C.
