Software/Firmware upgrade - TM-2030
The TriMetric TM-2030 is the most accurate battery monitor available for RV, off-grid, and marine battery systems. Unlike cheap voltage-based monitors that guess your state of charge, the TM-2030 uses precision shunt-based coulomb counting — measuring every amp flowing in and out of your battery bank to give you a true, accurate reading at all times.
When your battery bank cost $2,000–$20,000, you need to know exactly how much power you have — not an estimate that's wrong half the time. The TM-2030 tells you voltage, amps, watts, percent full, amp-hours remaining, days since last full charge, and efficiency over time.
Designed, built, and supported in Los Gatos, California. When you call or email us, you talk to the engineers who designed it — not an overseas support center reading from a script. That's included in the price, for the life of the product.

Why does it cost more than the alternatives?
You've probably seen battery monitors for $35–$80 on Amazon. Here's the honest difference:
Your battery bank cost $2,000–$20,000. The monitor watching over it should be accurate. That's the whole point.
