To keep a unit that floats balanced I am looking to use two battery packs, one on each side of the device. Each pack is 7.4v/3600maH. I would like to connect them in parallel in the unit to extend the runtime, and I was wondering if there is any issue with doing this? Packs are made by Turnigy and have the associated protection circuit in them.
The packs will be removed from the unit and charged independently when needed.
To me I think there will be no issue as the packs have their own protection circuits built in, but I thought I would get a second(or third, fourth etc...) opinion on this.
