I recently bought this at full price I am getting paid for this was not free (Lithium Lead-acid Battery Capacity Tester 30V 20A 150W Discharge Battery Tester)
https://www.ebay.com/itm/38444852660...53.m2749.l2649
MD150 discharge tester parameters
Model MD150 discharge voltage 0-30V
Discharge power 150W, discharge current 0.1-20A freely set
Equipment power supply: DC12V/2A, operation mode, discharge manual switch
Error 1% heat dissipation temperature controlled fan (maximum noise about 60dB)
Note that the positive and negative poles are not allowed to be reversed
Discharge mode constant voltage, constant current, constant power, constant resistance, dynamic load test
Size 15.3*14*9.6*13.2cm
Display parameter charging: voltage/current
Discharge: measured voltage / cut-off voltage / initial voltage / average voltage measured current / set current / capacity / power / temperature / power / internal resistance running time / discharge curve Software required which does not come with it )
It has one nice feature it has temperature cutoff control this is a plus when you want to torcher test a battery pack and want to if can handle it
It can load test up to 20 amp depending on voltage input
You can also adjust the current on the fly as well
I have only briefly tested it so far
When I get more experience with using it I will add more comments to this post
