If you're doing it "properly" why not just get a proper loadbank? https://crestchicloadbanks.com/dc-direct-current-loadbanks/
Did I say I was doing if " properly"...? I did not mean to, if I did.
I thought I said:
I was doing it cheap, diy, and quality, @ home. I can do all those things that the load bank can do, just dont know how yet. Exactly.
I mean, why spend more when you can spend less? I need not meet any standards or certification. I am doing it for me and my DIY customers. Who want to know the specs and tenacity of a cell. Spare time messing around. I cannot mindfully sell someone an assembled pack without a test first. For both record and security.
Yes, the range of those ( professional built load banks, that I didnt even know exsisted, designed by some busines that has to pay taxes and whatnot, increasing cost of product) is a good template. Range from 24v/100A up to 700v/450A So I am right in the middle with 240v and 20Kw.
I mean, I have my own (machine design) expert and I have the same ability to blow air over a calculated Ohm load as the next guy. I dont think I want to waste money o paying for their labor when mine is free.
So I got: The nichrome idea, the strip heaters idea, and the water through a stainless tube idea... All I need is the circuitry.
Most proficient for me I think are the heaters in an enclosure with forced air. ( sorta just like the "proper " installation you just told me about... ).... ( mebbe I'll buy one just to copy it and send it back lol... Nah that would be dirty.. Using someone elses product for copy... I am not buying someone else design, or copying, I am making my own, here with our lil ol' engineering co... )
I mean What the f-u-ck, you guys. Do you want to see me do this or not? Yes Grin makes one. Yes, you can buy a 5,000$ heaterfan in Pottstown.
Yes I have more than a "single setup" with huge "range accuracy and clumsyness" to discharge single 18650. 400w is wimp. 4 in parallel for 1200w is wimp. A SINGLE resister I have is rated at 1250w. I have 14 of them.
Yes My power supply cost 5000$ from AAB. You can buy one new today. On eBay they sit for 2500$. I paid 40$ for two of them, and sold one for 400$. Dont tell AAB. They might get mad. I am budget oriented and have no restrictions requiring me to buy new equipment.
Yes I have what is needed to do it, and do it DIY. Thanks all of those that have given me constructive criticism, but....you critique is not very rational in my opinion. If you have actual numbers or ideas other that " buy it" or "
