Do they emulate duracell leaks? if not, then it is incomplete....

Another great teardown! Thanks for recording in fork-A so we can see all the great details. I always learn so much when I watch your videos.

If you don't need uA and can get by with a few mA accuracy, you can use an Instek GPP-4323 power supply to emulate batteries. Two of its channels can be configured as loads and with a little bit of clever instrument programming, you can wire up a load channel and supply channel together to act as a two quadrant thingy.

Janky, yes, but effective, and 1/10th the price.

4:40 4-Quandant is about sourcing and sinking negative voltages in addition to sourcing and sinking just positive voltages for a 2Q supply.

Glad that you made a teardown! I was so hyped and curious for the inside from part 1.
Thanks!!!

I really like the overlay of specs and other info during the disassembly. Keep this!

About the relay you talked about at 15:31. It might be the output relay to ensure complete disconnecting of the DUT from the source. It is well explained in Keysight University course PRACTICAL POWER SOURCING AND MEASUREMENT CONSIDERATIONS.
- lesson 2 12:00
- page 45 on the handbook
(apparently I cannot put links in here)

that little ceramic capacitor PCB might be a result of supply chain problems.

Just some detail: ST and Bosch are sharing not only their semiconductor processes, they are sharing the font of the chip markings too. Bosch is easily to tell, they often use a data matrix code on their chips for traceability.

Yeah, a thing of beauty, a joy for ever. Definitely a nicely built device. Easy to discombobulate and recombobulate.

Planar transformers, definitely an interesting thing. Thermistors on the output connectors? Interesting too. The power supply looks like it means business and does it well.

Perfect timing. I have my first battery powered project on the horizon and it will not be easy. Product manager is looking at 5-10 years out of a lithium primary so no time to test in in real life. The device draws high currents for short times. It would be very nice if you could show the capabilities of this beast when it comes to simulating pulsed load reaction if a battery.

On one hand having the fan keeping it cool for the many hours it will need to run may seem like a good feature but at that price point you are maybe expecting a passive cooling solution for multiple reasons including price. Keeping dust out, no fan to fail and cause failure of the device, noise, probably keeps temperatures more stable which I think may be a good idea for sensitive test equipment, I'm sure some of the things I mentioned are not important and there are some things I've missed but I'd like to hear your thoughts on the subject! Thank You For Your Time And Effort!

Was waiting for this after watching the first video on it.

That unit looks like it was well designed a built looks worth every penny !

Cheers for clearing up the confusion. 😂 ‘A battery emulator emulates a battery’

Someone had fun laying out the power supply.

I'm not so savvy, so I really enjoy sitting in on EEVblog videos. #sponge
