Default Receiver batteries

When using two receiver batteries, do I just wire them parallel. Both are exactly alike.

Default RE: Receiver batteries

It's possible. The concern is to make sure that both are at the same state of charge when connecting them in parallel.
Otherwise, the weaker will draw from the stronger, until they are equal in charge. It's usually better, at least in principal. to use larger capacity single battery packs. If the battery pack output voltage has enough "margin", diodes can be used to "decouple" the battery packs. The diodes must be identical, have a low forward resistance, and appropriate current and voltage ratings. However, as the parts count goes up, the chances of failure also increase.
