Clarification would be greatly appreciated since I thought the number of parralell packs x capacity gave the total capacity.
I'm not good at this 2s 2p stuff.

To clarify this.

1, I am using 4 Makita cells for the TX.
They are 1500 ma each and the nominal voltage for each cell is 3.6 volts.

2. The 2 packs consisting of 2 cells in each pack are in parallel.

3. That theoretically gives me a 3000 ma pack at a nominal voltage of 7.2 volts which is perfect for the Royal Evo TX. It needs the extra capacity due to the synthesizer and the scanner that are installed in it.

It is unlikely that the 2900 ma Molicels will fit into anyones tx with the possible exception of the older Multiplex "Pizza box" transmitters like the 30 30 and 4000 series.
