Thanks Peter and Antonia.

Those switches look nice but as my main aim is reliability I think I'll stick with directly plugging the batteries into the receiver (via diodes). This minimises connections and component count.

It is a bit fiddlier than switches every time I want to fly, but the first models I'm converting to 2.4 are all large with accessible receivers - even my big hands fit.

When I get round to my smaller models where space is tight, I may try the T9 switches Antonia mentioned - they have a nice battery backer function too.

Thanks again.

On bigger models i do away with switches now, and just solder a multiplex greenie to the battery. Remove the greenie to disconnect and no wear on the RX or battery connections. If you then use diodes you can also charge by building a standard charge lead you make up to plug into you greenie so bypassing the diodes. With a two batt system has the advantage the battery and rx connection is fully redundant to the RX. This is not the case with the jeti bec 2, with 1 lead into RX. Obviosuly you need a spare input into the RX. I use two LiIons that a wired using a standard 4S balance lead and i can charge them and balance as a 4s pack from one input to the battery charger.
