Installed the Drok Batter Monitor System into my 2018 Nexus RV 27V. Had to wait to get the DC systems re-wired. Seems nexus didn't know how to do any kind of electrical. Anyhow, this should help and we now have the flexiblity to turn the system on and off at the shunt and the monitor. The range isn't to great, but it does the job. I can afford to have the wireless connection to go in and out, as long as it updates every 10 seconds, I'll be okay. Stayed locked to wireless through several walls and lead batteries for about 4 hours at a time... then momentary loss of lock.
