I asked this awhile ago and got no responce so I'll try again.
The idea was to wire 2 TP1320 together and get 2640 mah and a total of over 20C discharge rate. Will this idea work? Two of those packs I believe weight very little more than the TP2100. You could then split them up to get shorter runs but better for stunts.
Is there a larger pack than the TP2100 that is a better solution?
Thanks

Electrically it will work.

You'll still only have 10C discharge rate, just the value of C will be doubled! (So you can discharge at 26 amps).

One safety concern is that a Y lead with deans connectors installed will leave battery voltage on the exposed plug when only one pack is connected. This is a fire hazzard if the exposed contacts are shorted. Its better to use one of the other connector types that dont have this problem.

Thanks alot for the reply! I have asked this question twice on this list and on other lists and yours is the first real reply.
Do you see any advantage at all with this kind of setup in any way?
Say If I used two 1000 mah packs each 10c in parallel instead of one 2000 mah 10C pack and weight is the same is there any advantage to the parallel pack?
There must be some reason I think that no one is doing this ,or is there?

Wiring two battery packs in parallel will double your run time. The only load increase you should see is to compensate for the motor having to work a little bit harder to lift the extra weight. Batteries don't put out power, they store power, motors draw the power they need from the battery. The only thing you have to be careful of is that IF the battery is only capable of releasing so much power at a time, then adding another battery could be hazardous as this could increase current in the wiring. I don't know the properties of all the different batteries, I work with AC power, but if you try this, be sure to check temperatures constantly.
