I managed to buy an EBC-A40L. I say managed, because apparently I got a bargain price, $173.63 off Aliexpress.
Good luck finding it for that now.
They raised the price and raised shipping by quite a bit each.
This is a 40 amp charger, and a 40 amp discharger specifically for testing individual cells, not batteries (limited to 5 volts or less).
Internally, it has a 5 volt at 60 amp rated supply. If you do purchase one, be aware it ships with a Chinese power cord rather than a US cord, and has a seal right next to the "only use 220 volt" sign. I had to open it up to figure out there is a VERY TINY window on the bottom where you can switch the internal supply from 220 to 110 (without opening it up).
Pretty darn easy to set up and use. It is an "industrial" device, in other words it is loud. It doesn't get hot, and despite the manual saying it is limited to 35 amps charging, it came setup from the factory to do 40 amps. I think the manual needs updating (and a better translation).
The software that came with it is easy to use.
So far, not problems doing exactly as advertised, charge and discharge at 40 amps, with data logging and fully automated charge/discharge/charge cycle. Not getting or running hot. I dislike the alligator clips, but other than that, not a lot to dislike about the unit. Voltage accuracy is very good according to my Fluke, start and stop voltages work as expected. Really easy to do a cell a day and leave them at 3.65v ready to assemble into a pack.
If you can find it at a reasonable price, better (and cheaper) than purchasing power supplies and electronic loads separately.
