Software/Firmware upgrade - TM-2030 & SC-2030

Sunlight-readable red LED display

The TM-2030's crisp red LED display is visible from across the room in full sunlight — and won't ruin your night vision during nighttime checks. LCD displays wash out in the sun and destroy dark adaptation. Red LED doesn't.

200+ ft WiFi range

The WF-2030 connects over WiFi — not Bluetooth. That means 200+ foot range, not 30. Monitor from inside your house while your batteries are in a separate building, at the bow while batteries are stern, or anywhere on your property.

Remote web portal — no subscription

Create a free account at wf2030.bogartengineering.com and your battery data follows you everywhere. Check voltage, state of charge, solar input, and temperature from anywhere in the world. Free account — no monthly fees, ever.

Amp-hour based charge termination

Think of your battery like a bank account. Every amp you draw is a withdrawal. To keep your battery healthy, you don't just repay what you borrowed — you repay the principal plus interest to offset charging inefficiency.

The SC-2030 and TM-2030 work together to ensure every charge cycle repays the full debt. You set the exact overcharge percentage for your battery's efficiency. Voltage-only chargers stop when the balance looks right. Ours stops when the math is right — eliminating sulfation in lead-acid batteries after every cycle.

Designed & built in Los Gatos, California

Every TriMetric product has been designed and manufactured in our Northern California facility since 1989. Not assembled — manufactured. Every unit tested before it ships.

Engineer-direct support

When you email or call Bogart Engineering, you talk to the engineers who designed the product. Not a call center. Not a support ticket system. The actual people who wrote the firmware and drew the schematics. That's included in the price, for the life of the product.
