Boondock Gauge: BMS & Propane

Boondock Gauge puts everything that powers your RV, van, boat or cabin on one screen: your lithium battery, your starter battery, your propane tank and your solar controller. It reads them straight over Bluetooth. No account, no cloud, no ads, and it works 50 miles from the nearest cell tower. HOW LONG WILL IT LAST? Open the app in the morning and see the battery's charge with the hours left at the current draw, the propane level with the days left at your recent use, the starter battery's health and today's solar harvest. WORKS WITH THE GEAR YOU OWN • Lithium batteries: LiTime, Redodo, Power Queen, Starry Sea, ECO-WORTHY 12 V, JBD / Xiaoxiang smart BMS, JK BMS and Daly smart BMS • Starter battery monitors: BM2 ("Battery Monitor") and BM6 • Propane: Mopeka Pro Check, Pro Plus and Pro-200, read without pairing • Solar: Renogy Rover, Wanderer and Adventurer with a BT-1 or BT-2 module Close the maker's app first: most batteries accept one connection at a time. EVERY CELL, EVERY FAULT Cell voltages and the spread between them, balancer, charge and discharge MOSFETs, cycles, temperatures and BMS protections. Read-only: Boondock Gauge never changes a setting on your devices. STARTER BATTERY HEALTH Resting voltage with full/good/half/weak bands for lead-acid, AGM or lithium, and the voltage curve of your last engine start. Imports the history stored in a BM2. PROPANE IN %, POUNDS AND DAYS Pick 20, 30, 40 or 100 lb, or type a custom height. The reading quality and the sensor's battery stay visible.
