Ecotech battery backup limited to 2 devices

[Hitchhik3r]

I have 2 MP40s and one vectra M2. I didnt realize the battery backup only provides options to plug in 2 devices. Should I just do one MP40 and the M2?

Personally, I'm in the same boat as you. I opted to power the MP40 over the Vectra because the MP40 will run longer. If you run the Vectra, you need the Vectra Battery Backup Booster.
