Cheap dc load

[masterx81]

Hi!
I need to buy an eletronic load, to do battery test, psu test, etc.
I was in doubt with the korad kel 103, the kunkin kp184, and the in the low range there is also an east tester et5410. The first 2 devices seem to allow remote voltage sensing, while the the et5410 seem to not have this feature (maybe can be modifed cutting the traces where is the voltage feedback).
In this so low range, what's the less bad device?
Thanks!

Have you looked at the SDL1000X series of loads ?

Love them (also had chanche to work on siglent scopes, and loved them too), but are a bit out of my budget. The cheapest one it's almost the double the price of the most expensive of the 3 that i've seen 😅
It's only for hobby use, i would love to have better options, but it's difficult to justify the expense.

Here is a review and teardown of the Kunkin KP184:

Uhm, missed that. Thanks! Not seem bad afterall, but the 1v minimum voltage can be a bit limiting.
To be fair, the korad costs twice as much as the other 2 units..
I miss only a review of the east tester unit, as for the korad unit there are some threads over this forum (but not a true review)

Now, the question... As i see, there isn't more with that low budget. So... The korad worth the 100e difference from the kp184? Thanks!

The Korad KEL103 (Starting @ 6:00) teardown:
Shows operating but mostly battery discharge (if you're into that).

At my last company I purchased a Tenma 72-13200 (Farnell 2848406). It works up to 120V at 30A and has control interface all for £194. Never had any problems with it so it may be worth a look. S.

I think that is a korad kel 102 rebranded... Thanks for the feedback! I'm still evaluating all the possibilities, but on that price tag, seem the best choice...

If it's just for hobby use and you don't mind messing around with Modbus (or software that is only available in mandarin) you could go for a Sousim electronic load: Absolutely barebone, but extremely cheap at roughly 40-50 bucks for a 200W unit (although i wouldn't recommend using it at that wattage for long):

Btw, this thing is tiny: It measures roughly 15x10cm, i was rather surprised how small it was when i recieved mine.
