Hello, I am currently working on a DIY tester with ZB2l3 ( nothing really new ahaha) and I would like to know which load give the best/real results.
ok I learned around about relation between load and test....
So can you guys help me finaly stick to 1 or 2 number for the load.
I mean should I use 7.5 ohm, or 3.75 ohm (2 x 7.5 ohm parallel) or maybe serie them, so 15 ohm ??
or maybe 10ohm, got 10ohm/10W, guess 10w is better because of heat and all that...
I know that, the choosed load (7.5 , 3.75 or 15 ohm) will be load applied to the batteries during testing, so load 1.12 A or 0.56A or 0.28A ( gotten with ohm law :shy: ....) so which combo, gave you best or real result with this tester??
PS: I already kind of did some dignostic on my ZB2l3, and voltage is surprisingly very pricise!! Lab PS 3.9V, and the tester also ready 3.9v (choosed any voltage just to see if this tester read the voltage correctly) so guess no need calibration, and mess its calibration.
Also checked my ceramic resistors, and I get around 7.6 ohm, maybe additional resistance of cable aligator clips... anyway I will go with those, that what I have at hand......
Info: I am a hobbist, I use 18650s in small project to make them portable, got a few 18650 from laptop batterie, and wanna stort them... So my use will not be very crazy load, 0.5A to 1A max , I guess...
So thx for any help guys
