I bought 5 of these to run discharge tests on salvaged laptop cells. All 5 worked first time and keep going strong as I cycle through dozens of salvaged Li Ion cells. Good - easy to use, visible display of total mAh, volts and watts in use. Not sure if 100% accurate but certainly good enough for my project to sort out similar capacity or defective cells from salvaged laptop batteries. Would be helpful if there were tabs to solder on the +5v required to power the units if you were making up an array of these to run many tests - otherwise you need a mini USB power source connection.

Easy to use and accurate readout of my 7Ah lead acid battery capacity. The cutout voltage can be set to what ever you want and can be left untill it cuts off automatically with tha final capacity displayed. I used a 12ohm resistor for the load which gives a 1A drain on a 12v battery which can get quite hot so some care is needed but apart from that this unit is great

This device works pretty well, although the instructions for use (as per the listing) are appalling. The readouts are fairly accurate (eg the voltage reading was out by 0.01V). If you buy this item you would be recommended to switch between the 2 resistors (either 1S or 2P) to ensure a discharge of 3A. You can set a termination voltage by using the OK, + and - buttons.

It does what it was supposed to and it has 5V separate power pins which is really useful

Very useful discharge batteries to your own specified limits, produces a results readings on completion of mAH
