Review: Perfect for trolling motor battery - I am using it for a dingy with 55 lb trolling motor and a 50 Ah LiFePo4 battery, and it is perfect for this role. 1. all info you need on one screen - voltage, current, Ah/Wh, remailing capacity. Having battery internal resistance and load resistance computed is also very useful. 2. it memorizes accumulated values (Ah/Wh) when powered off - no need to use an optional backup source. You manually reset these values after fully charging your battery. 3. it also measures all parameters when charging (charger connected to "load" terminals) - so you have exact Ah/Wh pumped into the battery even when your charger doesn't show it. Overall, a well designed device. Instructions in English good enough, readable and clear.
Review: Neat product, good value - Arrives in a nice package with meter, shunt, wires, and instruction sheet. Unit is small, smaller than you might think from the picture. Which can be either good or bad. Instruction sheet reasonably clear on hookup. Except it doesn't say how/where to connect charger. The ammeter is unidirectional, which seems to mean current flowing in either direction gets added. Which in turn means the counts on AH and WH increase as a result of current flow in both directions. I think this means that if you connect the meter like the load, the counts will increase as you charge, and increase further as you discharge. And if you charge and discharge simultaneously, the counts will increase based on the net. Alternatively, you could connect the charger directly to the battery, in which case the meter would only count discharge loads and ignore any charging. Or you could get two meters, with one and its shunt for the load and the other and its shunt for the charger. Instructions obviously translated from Chinese. Good enough if you have a basic idea of what you're doing anyway. Some notes: a) the unit has label "External resistance", which seems to be listed as "Impedance" on the instructions. b) the instructions use the term "Bring load voltage", without defining it. Presumably this is the voltage across the load at the current point in time. c) Internal resistance is defined as (full voltage - bring load voltage) / bring load current", which maybe means drop from full voltage to now voltage, divided by now current - but I'm not sure what sense to make of that quantity. The voltage range (min and max, for showing battery bar graph) and current range (max, determined by shunt in use) can be set by alternating between long and short presses of the single front panel button. Which is small and requires a screwdriver or pencil or such. Similarly, the AH, WH, and run time counters can be reset. Meter has two modes, working mode and dormant mode. Dormant mode shuts off the backlight display and stops all measurements and calculations. Instructions report power consumption 0.031.2W in normal mode, 0.5mw-0.5W in dormant mode, dependent on voltage value (higher voltage, higher power). Don't yet have a sense for accuracy. Lots packed into a small meter for a low price.

## Questions & Answers

**Q: Could this meter be used to test a 24v lifepo4 battery for 280 ah rating? would mah be coverted to ah measurement?**
A: Depending what kind of test you want to perform, yes, it could be useful.  You could test the voltage of the battery when charged and discharged.  You could test the current the battery outputs with different loads.  And you could measure AH and WH output by the battery in different configurations.  I don't know if it will display AH if it gets that high, but of course you can convert mAH to AH by dividing by 1000.  A 280 AH battery sounds pretty big, possibly able to feed more than 100A, which would exceed the specs of this meter.  So either keep the loads under 100A or else get a different version of this meter with a different shunt bar.  If all you want is a simple "good or not good" battery tester, there may be better products than this.

**Q: Will this read all the amh (675) from six 6v/225amh series/paralle set up? Or just the amh from the bat it is connected to?**
A: If you run all negative current for all batteries through the one shunt then it would read for those batteries.  Because my two banks of batteries are wired separately, I'm going to put in one meter for each bank. Meters are cheap enough, though wiring may be a pain either way you choose.

**Q: Will this tell me how long my batteries will last under the current load?**
A: Amp Hours of the battery ÷ current draw = time
Should give you an idea of how long. The output voltage helps, but varies with discharge rate. 
The anp hours are likely rated over a 20 hour period. You won't get that at higher draws.
For better battery life, don't go lower than 50% depth of discharge in amp hours.

**Q: Does this unit display live amperage, either plus or minus amps going in or out of the battery? Not a cumulative total over a time period like most?**
A: It displays live amperage, always positive, regardless of direction.  And it displays cumulative AH, WH, and runtime.

### ⭐⭐⭐⭐⭐ Excellent accuracy, incredible value for the money
*by D***B on October 27, 2020*

I purchased the 100amp version and was pleasantly surprised by the accuracy - even when running a 0.5amp load.. Accuracy was confirmed for current and voltage readings with calibrated multimeters. Easy setup, the diagrams in the instructions are very clear and are conveniently reproduced on the back of the meter itself. The meter frame has snap fit tabs for mounting in a panel, cabinet or case. The interface for setting the meter to the correct voltage range for your batteries (which you must do to get accurate state of charge info), clearing readings, etc is a little fiddly and inconvenient, but works just fine. Keep in mind this is a meter only, it will only take measurements of how much power passes through it, it isn't smart enough to track charge/discharge, and will not do anything to prevent over charge or overdischarge of your batteries.
