Hey everyone... hope your summer has been as enjoyable as mine. (...loving the cooler than normal weather!!!) I recently installed a new pm4b 75amp charger and Trimetric meter. My batteries are 4 T...

Yes that 1 volt during absorption makes all the difference.
PMB voltage does not need adjustment. PMB needs a timer to delay the drop to normal 13.6 volts for 90 minutes. Or better would 1.5 times the duration from start to 14.6 volts similar to Battery Tender brand.


i generally do not discharge very deep, so a timer would be best for me, otherwise a 1.5x delay would only buy me more minutes, rather than hours.
