I set it up according to the the directions... Mode1: P 24 (lead acid 24V), Mode2: Off (No time-out on display), Mode3: 21.6, 25.7 (0%, 100% SoC), Mode4: 22.0 (low voltage alarm), Mode5: 30 (did not change), Mode6: Off (no temperature display), Mode7: 29.3 (High voltage alarm). It works exactly as stated. Note there is a small amount of error in the voltage reading verses my $300 Innova meter, but it's pretty insignificant. A few noteworthy items: 1) This predicts battery state of charge (SoC) purely as a function of voltage. It uses a linear scale with the voltages setup in mode3. 0% at the low voltage and 100% at the high voltage. Unfortunately lead acid battery SoC curves aren't really linear vs voltage, but it gives you an idea of where you are at. Also as the voltage fluctuates with device loads, the SoC reading will fluctuate right along with it. For me it's not a problem, I only really pay any attention to the SoC% (and the Voltage readings for that matter) after a settling period with the trolling motor not being used. 2) The device uses power even when the display is off. With the display on and the light on, the unit consumes ~9mA, with the display & light off it consumes ~1mA. This might not be a problem depending on your application, but I store this boat over the winter and don't want any additional parasitic loads or to have to disconnect the batteries every time, so I installed a water proof switch inline with this device to truly shut it down when my boat is not in use. 3) The display is quite small. I've not used it on the boat yet, so I can't comment on how easy it is to read mounted 6 ft away (near my feet) in bright sun light. I'll update this later. Update: Installed on the boat and can easily be read from 5-6ft away in most lighting conditions. Note that the glare of the full sun can make any display hard to read. 4) The alarm can be silenced by pressing the mode button for less than 1 second. 5) The temperature display is only available in Degrees C. I live in the US and prefer Degrees F. I shut off this temperature display, because with my 24V system and the temperatures I mainly use the boat (20-30C) combined with the small display size, I'm concerned it could easily be confused with the Voltage reading. How water proof is it? Time will tell! It will get a full test mounted near the bow of my boat. I'll update this review if the unit fails due to water intrusion. I like the fact that it can be set up for different types of batteries. I plan to upgrade my boat in the future to LiFeP04 batteries and will only have to make a small configuration change to this unit. Review: Perfect - Has worked great so far, nice and simple ## Features - APPLICATION --- The battery testers can be used for testing battery voltage and capacity for electric motorcycle, motorcycle，golf cart, automotive , car, marine, RV, boat, etc. - APPLICABLE BATTERY --- The digital battery monitor is suitable for 7-100V (12v 24v 36v 48v 60v 72v 84v) Ternary lithium battery, lead-acid,AGM battery, LiFePO4 battery.
