iambyrdman Posted January 28, 2020 Report Share Posted January 28, 2020 I have 8 DNA 250C Setups and want to keep them all charged. So I took 8 USB cables and spliced the Red and Black wires. When I plug one into a Windows Machine it tells me something is connected but they do not charge. Does the DNA board need 1 or more of the data lines? I'd sell most any if you want one! I don't need 8!!! Link to comment Share on other sites More sharing options...
Vapors Tongue Posted January 29, 2020 Report Share Posted January 29, 2020 3 things here are wrong , 1 your computer wouldnt push more than 5 amps , 2 the wire wouldnt support more than 5 amps and 3 this is dangerous - what you need is a powered usb hub with at least 8 usb slots powered by your house hold plug and 8 separate usb leads you can also connect the hub to the computer but the hub is still going to be needed to be plugged in to the socket.

drjohnson61 Posted January 29, 2020 Report Share Posted January 29, 2020 I'm surprised it didn't blow the USB port or the entire motherboard! Unless they are built in LiPo, I would use a battery charger and I wouldn't use my PC to Charge, Just For Upgrading. Link to comment Share on other sites More sharing options...
iambyrdman Posted January 29, 2020 Author Report Share Posted January 29, 2020 I'm using a 5 volt 20 Amp block I built and I didn't pug all 8 in at 1 time to test. I just plugged 1 into a widows machine to see it would chime when I plugged it in to tell me a connection is being made. As I said, it was but not charging, why? Is that ok? 100 Watt charge block? 5 Volts at 2 Amps (10 watts) each when charging, right? Thank you for your wisdom, I understand. But anyway.... Back to the original question. Does the DNA board need more than the red and black wire in a usb cord to charge? Yes or no is a good start... Link to comment Share on other sites More sharing options...

I built a 100 watt 5 volt box for this and other projects. 1 Link to comment Share on other sites More sharing options...
awsum140 Posted January 29, 2020 Report Share Posted January 29, 2020 How did you determine it was not charging? The 250C stays "asleep" while charging unless charging display is turned on in a theme, I think. The USB connection, for Windoohs to see it, needs a data connection, not just power. In any even fooling around with a PC USB port like you are is crazy. Mobo or port can be too easily damaged. Buy a multi-port wall war as has been suggested and forget the kludge of eight off a single USB connection. A single USB port, on its best day, would smoke with the load to two 250Cs charging, let alone eight. I'm a kludger, too, but wouldn't do that kind of kludge.

dwcraig1 Posted January 30, 2020 Report Share Posted January 30, 2020 Then there's this, if you are only using one and are keeping the batteries fully charged in the other 7 then your batteries life will get shorter. Removing them from a mod when not in use is probably best. The voltage on a cell being stored is best kept at around 3.6 volts. Link to comment Share on other sites More sharing options...
iambyrdman Posted February 11, 2020 Author Report Share Posted February 11, 2020 I agree with most, if not everything. Perspective is everything. I really do try to use a different one every day. I have 2 Paranormal 250Cs to add to the mix to make 10. I had a set of 6 USBs that I lost, for some reason, don't even remember how now.... They don't all stay charged all the time, not by a long shot. And I use them for other stuff too. At my bar I hang out at all day... Most have built in 21700 pairs without sleds, permanent like. I have a 3D printer now, I should just print some sleds how I want them! Thanks for all you wise insight and wisdom! You are awesome, smart too... Bought this for now, easy... https://smile.amazon.com/AmazonBasics-60W-6-Port-Wall-Charger/dp/B0773K737F Link to comment Share on other sites More sharing options...

So, I printed the first sled. Super easy print. Took about 3 hours. Link to comment Share on other sites More sharing options...
