LiPo's in parallel

What are the problems of running Lipos in parallel? I would like to run a 4s 4000mah 25C battery in parallel with a 4s 1800 mah 25C battery to minimize voltage sag without adding too much weight. I also plan on only using about 50% if capacity.

No problems at all. Just check that both packs are at same voltage before making the connection.

Yep that will be fine. I've done parallel pairs even less alike without any problems. Just make sure the connections are all solid because you are adding extra wire and connections to the system.

Should be fine however I would recomend checking each batteries indivual cell voltages after a flight and also charge seperately and note percentage of mAh replaced in each.
