DIY Battery Monitor for Furnace TESTED!

This video details the setup and testing of a D-rock battery monitor with a furnace battery backup system. The goal is to accurately track power consumption and evaluate the performance of lead-acid batteries, with an eye towards a future upgrade to a custom-built lithium titanate battery bank. The installation process for the D-rock monitor, including splicing the shunt into the negative side of the battery array, is clearly demonstrated. The video documents a capacity test of two 105 amp-hour lead-acid batteries, wired in parallel, used for a furnace backup during cold temperatures. The test ran for an extended period, yielding impressive results of 1516 watt-hours and 63.17 amps per battery, exceeding initial expectations. The D-rock controller proved to be a reliable and affordable tool for monitoring battery usage, providing valuable insights into battery life and performance. The video concludes by looking ahead to building a lithium titanate battery system for even longer backup power.
