Go here: http://personal.lig.bellsouth.net/lig/r/e/redscho/ I have been running dual battery packs and two switches for years. There is absolutely no need to use "backers" , diodes, or anything else. Simply plug 2 batteries into 2 switches (or even "Y" them into a single switch) and plug into the RX. All you need to do is make certain you use packs with the same voltage, i.e. 4.8 or 6.0 volt (4 cells or 5 cells). The capacity is additive, two 1,000 mAh packs gives you 2,000 mAh total capacity. The enclosed link explains it very well. If you are worried (incorrectly) about a "full" pack charging a "dead" pack try this (I have). Cycle 1 pack down to 1.1 or 1.0 volts per cell. Charge another pack fully. Plug them both into the same RX. Go away for a couple of days. Check voltage when you come back. You will find that there is very little voltage transfer. SO keep it simple. Why add additional potential failure points when they are not needed.? In my Scale ships and large scale aerobatics planes (large gassers) I run dual 2,700 mAh or 4,000 NiMH packs, 2 switches, no backers, diodes, dead chicken entrails, etc. Very simple and proven in over a decade of this type of use. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Bill Malvey Ladera Ranch, California RCSE-List facilities provided by Model Airplane News.
