Has anyone tried the Bogart Engineering’s “TM-2020 Trimetric Meter Battery Monitor”? Great write-ups etc., but would be interested on seeing comments from “Cartaholic” before I order one. If no one has, I may go ahead and give it a shot. Seems like the perfect way to keep watch on your cart battery and get the most out of it. Provides amps, voltage, amp-hours available/used, % full, days since last fully charged, days since last equalized, cumulative amp hours, max. voltage and minimum voltage history, etc. Requires programming of total amp/hour capacity of battery. 4.5” x 4.75 “ x 1.75” dash mountable. Two twisted pair, 22 gauge wires to battery and current shunt. Only draws 16ma with display off.
