Certainly if you want to do 1 cell at a time. Of course you can buy 4 of them and do 4 cells but then you might as well buy an OPUS and it will charge as a bonus. Smile

Now once you build your Packs you can certainly test the Packs with it so you can verify that all your Packs are pretty much equal.

I bought one of 'these' (similar look/feel) but it stopped working after just a few hours of use.
I might suggest an iCharger X8 (or X6)  https://www.amazon.com/iCharger-Lilo-Bat...B07Q8WP4RN
The iCharger will likely last much longer and certainly has more sophisticated features - I particularly like the easy auto-off by voltage on discharge so I don't have to watch it closely when using it Smile

Almost all of those cheap electronic loads you see on eBay, Ali, etc are junk. However there is one superb 150W 60V/10A load that can be had for about $25 that I described in this post.  The latest version claims to do DC IR tests too.

I have two and they have held up well under heavy use over a few years (and the factory calibration is good down to a couple mV/mA, better than many cheap DMMs!). 

Otoh, I've lost count of the number of bad reviews I've seen of similar units, which often don't come even close to handling the rated power, are made with used parts, and seem to be designed by someone who barely knows electronics. I read lots of electronics reviews, and these loads count near the top of the list of stuff I've seen that is almost always very low quality. If you buy a random unit it will almost surely be low quality. In fact - off the top of my head - I can't think of any other device where there is currently only one known good choice among cheap Chinese units.

Read the above linked post to learn more (esp. how to avoid the identical-looking low quality clones).

Not according to reports. In RC forums many Junsi iCharger users claimed their iChargers died soon after nontrivial amounts of discharging. Many stopped using them as dischargers due to such. I don't know if this has been fixed in later models since I haven't been following such in the past few years.

Most hobby chargers simply don't have adequate thermal design to survive much use as a load. Better to use a dedicated load that is designed to handle the heat.

This is what I was looking for... feedback for a "known good" one

I will see vid and reviews...

Love the price Smile

I use a 100a power meter and a 300w 12v heater blower for 12v capacity tests. they can be wired in a series for higher volt needs.

   My setup pulls over 450 watts at 14.4 volts @30.00$US  total
