The iTECHBM500 Battery Monitor delivers real-time, high-precision insights into your battery’s performance. Using a 500A current shunt, it accurately tracks both charging and discharging currents, calculating Amp-hours (Ah) flowing in and out of the battery. A field-installed sense wire enables precise, live voltage readings. Designed for versatility, the iTECHBM500 is compatible with lithium, lead-acid, and nickel-metal hydride batteries.
