Jeti (or other) electronic switches and mAh telemetry

I just pop a meter on my packs during the day. The packs are usually fine for 3-4 flights and I never get that many flights in! I did use the Jeti remote switch. It drains the battery listening for commands but it’s pretty cool!

I don't really have a need for a magnetic switch but for the telemetry data I use UnisensE module. Works with most brands and I get all the data I need on my Jeti...

Your setup should tell the possible options and their size. Tell us more!
For my Lama Vario T-Rex I got Emcotec 100/200 and three OptiPower modules: Backup + Flash Alert + Anti EMF/Power back.
Switch is convenient to connect the batteries in advance with no fiddling of the heli at public show.

I use the EmcoTEC for both turbine ECU and receiver switches in the Lama and Bell 429. They work well for me as the whole system becomes hidden below the floor when installed. EmcoTECs, for some reason, are hard for me to procure, not that I need one now. I like to keep a spare as a simple reversed polarity will destroy the units. Because I switched to Jeti and a whole new world of telemetry, I wanted to ask what others use. Also, wanted to know what mAh is used as I do have to remove the entire floor assembly to access the batteries. No big deal…but a task. Some might ask why I have redundant batteries….I like redundancy and the weight offsets any lead shot I have to put to balance the heli.

What I have done for my Lama is simply to add two tiny wires in parallel (not in serie as usually) to snif the current voltage and this is connected to the external telemetry voltage input of the 7008SB.
At some pre-defined low voltage I know it's time to land and there is approx. 20% battery left under load (not using old Lipos).
Never had an issue doing this cheap way and countdown timer is enabled, whilst I know that reading the tension in serie is best (look after the old IISI Cockpit V2 TXEs options about measurement methods).

Otherwise I use PowerBox with telemetry (2x2500 Pro).
