I think you'll be more than happy with those packs. Dual 5s 2.5Ah is the same setup I'm running in a few vehicles, except in a single 5s2p format, and they work great.

On to your question: Not gonna happen. Even in you paralleled the 5s1p packs as a single 5s2p pack giving you the same 5Ah setting, the voltage is not the same as a a 4s pack of any capacity. Doesn't the duo have profiles you can select from? Just set one to charge your 4s PQ packs and another to charge Mike's packs.
