Review: Excellent , simple , accurate unit - Worked perfectly right out of the box. Nice heavy duty acrylic base and super heavy hardware. Simple operation is refreshing in this overly gimmicky app-inundated world we live in. Some other manufacturers could take notes from this monitor! Others have said there is no way to secure it into your cutout if you can’t access the back. I can confirm that. However , a 2 1/8” hole saw produces a perfect fit in plywood. I didn’t need it but one could add a single layer of electrical tape around the perimeter for a super snug fit. Yes, cord is too short. Ended up being just enough for my application. You can extend it without too much trouble. It’s a standard 5 pin JST-XH. Battery sampling wire I used was 18awg. The screw terminals on top of the unit worked great. Philips, very small. Consider tinning the end of your wire and then smashing it flat and trimming it square for a good connection. 18 gauge is probably about as big as it will accept. Even the backlight is great. When the backlight is turned off the screen still glows ever so slightly so you can read it. Perfect for nighttime in the woods. The screen is quite shiny so consider glare from windows when installing. The accuracy of any monitor depends on your configuration! For my one year old AGMs I used 50% of the rated capacity and charged them up fully with a good 3 stage charger before connecting this monitor. Then set the current SOC to 100 and forgot about it. I set zero % SOC voltage to 10.1. Have a couple weeks camping in the RV so far with good results.
Review: Easy to Install, Easy Initial Setup, Accurate Indication of State of Charge - I installed this meter in my DIY portable solar generator that I recently retrofitted with four 3.2V 280Ah prismatic LiFePo4 cells after many years of using AGM batteries. Neither the solar charge controller or my simple voltmeter were able to measure amps in and out to provide an accurate indication of state of charge for the LiFePo4 battery. This current meter was easy to install, and if you follow the directions carefully, is easy to calibrate to the specific capacity of your battery. While it lacks Bluetooth connectivity, it is offered at a price point that makes it an exceptional bargain. The shunt is well made and appears to be of durable construction (I chose the 350A version). The meter is flush mounted and of very low profile. The function buttons work reliably and while the display options are quite simple, the information displayed is critical for clearly and accurately presenting the battery's state of charge, which is calculated as a value of remaining amp hours and as a percentage of total capacity.

### ⭐⭐⭐⭐⭐ helpful gadget
*by P***H on July 22, 2022*

simple tool to help monitor battery health. it gives discharging OR charging status, one or the other, not both at once. in the end, total Ah discharged is our main focus so we can learn our overnight consumption. have 2 200ah lifepo4 batteries from amperetime. easiest to set meter when batteries are new and fully charged for accurate display. as they age, resetting Ah capacity will be necessary to stay in ballpark of actual Ah capacity but that is to be expected of most basic battery monitors. the trickest part to get Ah IN from solar charge controller as well as see Ah OUT of the battery bank was to put the SCC and inveter cables for the negative side on the P- end of the shunt and NOT use a hopper from P- to the copper bus bar amperetime recommended when we paralleled our batteries. our battery negative cables are on the negative bar and all positive cables (SCC, Inverter and 2 battery lines) are on the postive bar but the meter would not count properly when SCC and inverter were on the neg bus bar. whatever...it works great now and we are pleased with our purchase. BTW, we use a victron 30a AC charger as a back up for when solar may not fully charge our batteries. in order to know exactly how many AH our 3 wk old batteries had, we discharged the bank to below 11v, (which was okayed by amperetime for testing purposes only), then one by one, we recharged with the victron to see actual Ah input to the batteries for accurate Ah capacity. after resting 12 hrs and good, close voltage we reconnected the pair in parallel and all has been working well to power overnight electric requirements and get fully charged by solar of the 40% discharged by mid day on roughly 220w max of solar charging by our renogy roverli40amp mppt charger.
