I meant this
Oh the DC jack. What do you use to terminate toā¦ a DC plug as well right? Can you link it.
I use these specifically, I like them because I can insert the positive lead into the positive terminal, allowing for shortest distance wire to contact
Wait what? Iāve used very similar barrel ports to what @gogomrrobot is using at upto 10A load at 24V and they where fine, though when using a very similar DC Jack like that it got crazy hot at only 5A. Iād recommend those screw terminals, but use male bannana plugs to put it in, donāt just screw a raw wire into it.
I got the male and female of these for 2$ go to your local electrical store if you need it fast and cheap
I have a question. How do you charge to 14s if the drok max output is 50V? Can you by pass it in the software?
Nope you cantā¦correct limited to 12S I got ahead of myself actually. I ordered a new setup already.
It uses these 3 piecesā¦
(I had this guy already from earlier this year)
Hooked up to this guyā¦below to limit the amperage to 12Aā¦

Hooked up to this guy to boost the voltage up to 21S ?..

Routed thru this sucker with a built-in shunt because I need a displayā¦

Then I will mount some potentiometers to replace the little screws on the regulators so I can mount those like knobs on an electronics enclosure.
Will I likely blow up my house when I try to step down the amperage that much? Yes likely but theoretically it should work.
Donāt just plug wires into it? What kind of banana plugs? They would have to be teeny tiny rightā¦ the opening to those screw terminals is very small.
Can you link any high current / high voltage DC jack male/females ? I feel like these tiny plugs and receptacles that say 5a-10a and 24V are going to blow something up. I want those thick ones. Should be worth the investment.
Thats some Doc from Back 2 the future stuff right there. Gonna power the flux capacitor with that!
Thanks for the detailed explanations @scepterr, @SilentException, @gogomrrobot. I think Iām gonna go down the 12s bluetooth route!
Yeah the up to 12S (50V) bluetooth route is a one day project once I got everything from Amazon. Ohā¦ and I used this Dremel metal cutting disc. Then painted the front and back black spray paint to hide my screw ups
Below is a picture of the plugs Iām using with my DPS5015. The bannana male plugs are 4mm.
And regarding your post just before this, are you using 3 different converters in your charger?!?! That is incredibly inefficient, Iām not sure why you donāt just use one or the other or use a higher voltage PSU. Oh and that 12V 75A PSU was kinda a scam, you can get used computer server PSUās for under $20 that output nearly 70A I got these two for like $24.
Two converters you mean. The last screen is just current voltmeter. It is for building a second box like what i just built.
Yeah i was trying to make up for a bad purchase by putting it to some use. Probably wonāt build a second box. Not sure I want to go beyond 5A charging you know what i mean?
Charge a large battery in 20 mins would be really cool
Do you have a build thread for the orange charger? At least some pics / stls?
Itās just some DPS5015 enclosure I found on Thingiverse Iām sure if you look it up on there itāll show up. And all I did was wire the output of a 24V 20A PSU to the inputs if the module and put it all in the enclosure.
Wait dude so your unit is 24v / 20 A PSU with a dps5015 step down converter. So the most you can charge is like aā¦5S battery? You would served well by that step up converter i linked.
Yes itās a 24V Power Supply but itās only my lab bench PSU not for charging any batteries. My charger for my board uses another 24V PSU, cause it was from when my board was 6S, and a LED Driver step up to charge my 12S. The nice thing about the LED Driver is itās a boost and a constant current module, though itās only rated for about 250W and it gets quite hot even with a heatsink and fan.
Never heard of a LED driver ā admittedly I am noob to all this and just started dabbling in it 2 weeks ago ā is that the same thing as a boost converter (or step-up voltage converter for that matter) ?
An LED Driver is just a module, usually boost, for driving high voltage LEDāS they usually also feature constant current as well.
In this context LED driver is usually a CC/CV PSU. High power LEDs also like to run on CC/CV (my flashlight hobbyā¦)
Iām fairly convinced that LED driver PSUs with adjustable voltage are more appropriate for bulk charging our big packs, but need to put this to the test.
