The only standalone touchscreen that monitors two lithium batteries simultaneously — compatible with Renogy, LiTime, EcoWorthy and JK BMS. No app. No subscription. Ever.
Built from the ground up for off-grid, RV, van, and marine installations. Fully autonomous — your screen, your data.
Everything displays directly on the 4-inch touchscreen. No phone needed, no account to create, no monthly fees. Works completely offline.
Monitor two batteries simultaneously on a single screen. See SOC, voltage, current, power, remaining runtime and cell data for both at once.
WiFi updates keep your monitor compatible as battery brands evolve. No internet needed for daily use — WiFi only for updates.
Set your own SOC threshold for each battery. When triggered, a physical relay activates — connect a buzzer, light, or any 12V device.
Powers via USB-C or direct 6–30V DC wiring on the rear terminal block. Perfect for permanent wall installations.
Fits any standard 86mm wall box — like a light switch. Clean, professional installation in your RV, van, cabin, or boat.
TrueState Monitor connects via Bluetooth directly to your battery's BMS — no shunt, no wiring, no adapters.
