Two chargers different voltage

[Vertigo]

I changed out my batteries today and put in a single 12v/300ah Li battery. I’m running two chargers, a Victron Solar MPPT 100/50 and a Victron IP22 AC 12/20 (back up). I also installed a Victron SmartSense for low temp cut off. Everything seems OK but when I check the Bluetooth app I’m getting different voltages off each device. I have them all enabled to fully charge the battery before I put any load on it. The SmartSense is showing 13.5v, the MPPT 13.54v, and the IP22 is 13.75. All are connected directly to the terminals. Why the variation in voltage and how do I know which one will throw the respective charge device into absorption? However, my multimeter reads 13.62 at the terminals.

I got it figured out. It took a couple of minutes of head scratching. When I disconnected the other batteries it dropped the network connection in the devices and I just had to sync them in the app again. The variation is now only 0.05 difference between the chargers and my multimeter.
