Li Ion in series?

my favorite is the long train down hill dead stop…

I run Del’s newer system in both my trail cars, but never bothered to tweak the low battery warning settings. My trail cars have sound and it’s pretty normal that I will loose volume on the sound system about 5 minutes before the battery shuts down. I’ve also built my trail cars to accommodate two battery packs with Tamiya quick disconnect plugs. So long as I stop in an accessible area (95% of the RR) it’s a simple matter to change over to a charged pack.

Jon,
That’s my indicator, too.
When the Px sound quits, it means I’m down to 6 volts.
I can still get the train to an easy place to swap batts.
If I’m using my one and only Li-on, she stops dead somewhere.

I am using LiIons and my Px doesn’t quit, but the volume gets real low a minute or two before the LiIon shuts off.

I had that happen this weekend on my NW2
