Do you think these would work?
When will you be releasing the schematic for your design?

I think they'll work great! Wow, just did a quick search and each of those modules are over 100 bucks at a surplus store - nice!
Connecting as you suggest would work as a low side switch (as all of my configurations have been). You'll have to add inductance to the output loop in order to limit the peak current every switching cycle. It might be a challenge to find an inductor that is of high enough value to limit current spikes at low amps (finishing taper charge) and can handle the high currents your module is capable of. Lead Acids don't mind (much) overcharging and current spikes, but not sure about lithiums. I haven't heard this aspect discussed much, though I don't know how much ripple current fancy chargers have. Might be something to check out - I'd hate for an expensive pack to be killed by high ripple current towards the end of charge.
I have some preliminary schematics, but they've long since changed - I'll have to update them and upload em.
