This gives me a more accurate idea of how much battery I have left on a trip and know when I need to turn back and head in. This monitor can be selected for many different kinds of batteries such as lifepo4, lead acid, and other battery types. I like the idea of setting the buzzer to go off at a certain level so that you know to start heading back home soon, but I have not set that up yet. overall i like it a lot, it's small, clear to read, and seems like a good deal so far. Review: Good non-shunt battery meter - Bought this to monitor the voltage on my 24V trolling motor system real-time. 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. ## 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.

Recommended. *by A***R on February 13, 2024* Installed this in my 2016 Club Car Precedent. First, this is NOT a state of charge meter. It provides real time voltage readings which change continuously while operating. I’m okay with that as,n the end, it provides more useful information as to what is going on. To get an actual “state of charge” value you have to stop and let the pack relax for a few minutes. Values are accurate compared to my hand held multimeter. Install and setup was easy, readout is bright and easily readable. Unit is fully sealed against water and I expect it to last much longer than the last two meters I installed which failed after they got wet. ## Frequently Bought Together - IPX7 Waterproof Battery Monitor with Bracket 7-100V,12v 24v 36v 48v 60v 72v Digital Display Battery Capacity Remaining Capacity Percentage Tester with Buzzer Alarm and Temperature - Club Car Replacement Golf Cart Keys (2 Pack) - 10L0L Universal Adjustable Golf Cart Panoramic Rear View Mirror, Rotatable 270 Rotation 16.5"Wide Angle Full Rearview Golf Cart Mirror for EZ Go, Club Car, Yamaha --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/531799977-ipx7-waterproof-7-100v-battery-monitor-with-bracket-temp-buzzer](https://www.desertcart.hr/products/531799977-ipx7-waterproof-7-100v-battery-monitor-with-bracket-temp-buzzer) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-24*
