The amp rating that you put on the battery is half the rating of the battery in CCA So the battery being 650 we applied 320 which is close enough to half the CCA of this battery If you look on the bottom scale is shows you the battery CCA being 650 which corresponds with the top load graph at 320A
@@RealAutoSolutionsExcept you are only supposed to go to half CCA, which in this case would be 325 on the bottom scale, would it not? Very confusing...
I'm confused, in the video you explain based on the direcvtions you want to apply 320a scael for the test, but when it comes time to test you bring it up to about 620...?
So the ammeter has 3 scales if you rewatch It is 650cca so half of that is 320A (not CCA) for the test we want to apply half the battery capacity But on the lower scale it actually is reading CCA so it's just a couple ways you can read the scale If you re watch the video you will see I apply the 320A but the bottom scale is the battery CCA which lines up at 650 which is what the battery is rated at
For sure there would be some, would vary car to car I guess depending on how well and clean the connection is The gauge on the carbon pile wouldn't be able to show us millivolts like the DVOM would
An electronic load tester that can measure 72v at 20 amp / 1440 watts would be expensive. I personally would use a 1500 watt electric space heater available everywhere and a DC clamp meter to measure amps. May have to modify the heater slightly (shorten the coils a bit) to accomodate the 72v versus the standard 120v wall voltage. Probably too much trouble to bother unless you're an electrical hobbyist, but the heater option would probably be the cheapest homemade way to do it. A DC clamp meter would be $50+ depending on quality.

I'm also confused...the amp rating would be about 160 and not 320? Please clarify. Thank you.

@BrewCityRider it's half on the top scale, it's battery cca on the bottom scale

You should explain how you arrive at different loads for different batteries and battery types ...
Some voltage drops on connection. I wander what voltage would be on battery terminals measured by multi meter.

can you use this to test a 72volt 20 ah lithium ion battery ?
Only 12v systems on this one mate, you can tell by the gauge in the RH side that tells you the charge
@@RealAutoSolutions Is there any way to load test a 72volt 20 amp E-bike lithium ion battery ?
Not that I know of, maybe a local bike shop can help instead?
Or even a local battery store?

It took me 5 hours to find this video so I know what the hell is I need to doing
Perfect
I'm happy for you
I’m looking at one for $129.00
Got a link to it mate?
