HV CAN PMU not working on 2S

Hardware Vendors CUAV

Hello,

I wanted a power monitor for my helicopter servo battery. The battery is a 2S Li-Po (7.4 - 8.4V). I ordered the CUAV CAN PMU module because it is rated for input voltage down to 6V. However, upon plugging in my freshly charged 2S Li-Po, nothing happens, no status LEDs come on anywhere.

Next, I plugged in a 6S pack, which powered up the module and connected flight controller just fine.

Anyone else have this same experience with the CAN PMU? Maybe it needs a firmware update? Maybe it really isn’t capable of less than a 3S LiPo?

Are there any power monitors available, without a BEC output, for the purpose of monitoring low voltage sources? I’d like to find one with digital communication for providing voltage and current data.

Anyone know if the Holybro PM02D Power Module actually functions at 6V or on a 2S LiPo?
