Trimetric TM-2025 Deep Cycle Battery Monitor System

Note: Requires either a 100 amp or 500 amp shunt. An "RV" version (TM-2025-RV) is also available - major difference is color.

The TM 2025 is intended to help maintain battery systems for 12V to 48V deep cycle battery systems, such as ones found in RV’s or off grid homes which are regularly charged and discharged.

Differences between the TM-2020 and TM-2025

The “amps” or “watts” display measures the rate of energy going in or out of your batteries so you can check your charging systems, and also to see how much energy each of your appliances use to help you conserve energy. The “% Full” display will help you keep track of how charged or discharged your batteries are. The “volts” display will let you discover if your charging systems are charging to the proper voltage, which is important for maximizing your battery life.

The “days since charged” display shows how recently the main battery (system) was fully charged, so if it hasn’t been charged recently you can perform extra charging if necessary to help maintain the capacity of your batteries.

The TM-2025 also can measure the voltage only of a second battery set, such as the starting battery, or solar voltage input to a charge controller.
