Best explanation I have seen and thank you for doing so. As a rc enthusiast and dealing with 6s 6000mah lipos I do wish there was something like this that can balance discharge while monitoring each cell. I bought this unit on Aliexpress and will use it.

Nice reviews.thanks

That's a cool tool! I bought one in 2021 when I built the 100-Ah LiFePO4 battery for my car. Like you, I tested capacity right away to see if I was getting the advertised spec. Thumbs up there. I do a full capacity test every November to see how much my battery has changed each year. I guess I should share my results when the time comes. 73! -Scott, KE4WMF

Mike that's a great tool. Very useful in testing both new and old batteries. Good price as well !

@jgschmidt56 5 месяцев назад

Nice review and good job on deciphering the settings. The little white plug on the right puts out 3V when it goes into error, so you could trigger something electronically when it's done.

@ravenbarsrepairs5594 9 месяцев назад

Had one of these for a few years, and haven't used in a while. Bought to load test a 12v power supply(matching supply to a Kris CB radio that's also on the project list) that's been on the project list for a long time.

Battery tester space heater combo. Kewl. But holy complicated instructions Batman! Thanks for the demo.

@spuriouseffect 8 месяцев назад

I just watched another video about this tester and they maxed it out for an entire test. I guess reading the instructions wasn't their cup of tea. Thanks for this! I used your affiliate link to purchase.

@hamradiotube 7 месяцев назад

Awesome, thanks so much. Glad you found this helpful.

@RicSpivey 9 месяцев назад

That does seem like a great tool to have!

@brianhendrix 9 месяцев назад

Now I gotta build a Anderson Powerpole short cable to put on the tester so I can connect batteries to it!

@hamradiotube 9 месяцев назад

No, you GET to build another Powerpole cable. Just like I did 🤣

@myrandabrown 2 месяца назад

Thanks for the tutorial. I’ve tried reading the instructions a dozen times and could never grasp what it was trying to state.

@robertmeyer4744 9 месяцев назад

nice review. I got one with black fan. different brand. but very close to that. same crazy menu. it does get quite warm at near full power. you can do USB C PD testing with a trigger cable. but limit on trigger cable . 73's

Thanks, I just bought this and need to test a 100Ah Lithium Iron RV battery. This device is rated at 150watts (?) but it also says 20A which is 240 watts at 12 volts so how should I set it? I want to draw 20 amps from my battery to test the Amp Hr rating. I guess I'll have to limit it to 12A in order to stay below the 150w heat sink limit. But it starts out at 13+ volts . . . Will this do a constant watt draw or is it limited to a constant amp draw?

RIP DenCo prototype batt. We can rebuild him... better, stronger, faster.

@barndweller4573 9 месяцев назад

This thing looks cool. Never really had a way to test batteries except to see if it would last all night. Lets see if I can smoke it haha.

@hamradiotube 9 месяцев назад

Fingers crossed!

@samthelion17 2 месяца назад

I wonder If you'd be able to supply 20v/5A to that USB-C port using one of those trigger boards.

@renk5000 2 месяца назад

Have some of items in your affiliate links in my cart. I would like to know if there’s wiring for 12v 100ah to this tester that can also be purchased on Amazon? I’m a bit dunce so any feedback is greatly appreciated.

@robertandrews2318 5 месяцев назад

What are the specs for testing a 12v 100ah sealed lead acid battery?

@John-dp3ln 5 месяцев назад

Anyone know how to hard reset this back to factory specs Mine was working, now can’t get it to adjust down, only counts up. Almost a wonderful thing, not a fan of the one control button.

@HAMFunko4pdi 8 месяцев назад

So i picked up this device and it works. So after 15 minutes at 2.0 amp draw on a 24ah battery it shows .77ah does this mean .77x4 AH used = 3.08, what does this mean overall? I am trying to find out if my battery is as good as rated. Do I let this run until I deplete the battery to get the total AH of the battery?

@hamradiotube 8 месяцев назад

That just means you pulled .77ah out of your battery. That seems weird though. With a 1 amp current draw in 1 hour you should see 1ah has been depleted. A 2 amp current drain in 1 hour should show 2ah depleted. 15 minutes at 2 amps should be .5ah. Did you hold the button down for a few seconds to clear out the screen before you started the test? I wonder if you may have had some data there if you were playing around with it before the test that didn't get reset??

@HAMFunko4pdi 8 месяцев назад

welcome home Mike. Ill reset it and try again.@@hamradiotube

Need to get a case 3d printed for it 73

@jerryKB2GCG 9 месяцев назад

wish this had an Andersonpowerpole interface, another cable to make up 😮

@hamradiotube 9 месяцев назад

Another cable you GET to make up 🤣

@jerryKB2GCG 8 месяцев назад

@@hamradiotube true, with enough practice I’ll actually be able to do that right the first time 😀

@ChrisCookTech 9 месяцев назад

So Mike, what did the POWERDRIVE 20ah battery actually supply in Ah? I have something similar and got 6ah out if it. Those chinese manufactures just slap on any label they want.

@hamradiotube 9 месяцев назад

I haven't fully tested that yet but i've had it for a couple years and have charged many things off of it. I would guess I get what it's rated for.
