23,07 €
Used to test 100ah lithium ion phosphate battery. Takes a good while but it works and it's accurate. It's a "leave it on overnight" job for big battery's. For your reference, on the fan is a QR code. You scan that to get the manual. You will need a power supply to run it. Will leave the leads with alligator clips I made up on the unit because they will be useful to you. Save you a job. An old router psu will power it if you don't have a lab psu.
