Good to know, I'll keep that in mind! Looks good, thank you!

Hey guys, this has probably been asked a million times before, but does anyone know of a good spreadsheet and/or graph that can show the input voltage and amperage of a18650 battery in comparison to SoC? I want to understand the relationship between voltage and amperage while charging so I can...

I haven't drilled the holes for the DC-DC, but it works! I know my wiring isn't exactly neat, but hey, it works!!!!! I'm more of a function over fashion person too. I bet people at school will be asking me questions about this (if they don't think it's a bomb). (note: this is a different...

Hey guys, my buck converter arrived a few days ago. I plugged in my eBikebattery to test it and it works! It doesn't have a display, so I had to use a voltmeter to set the voltage. It has a current adjustment setting as well, and it claims it can do "up to 20 amps". [/URL] My laptop won't charge...

May actually be a battery issue. That'll be a lot cheaper to repair More 18650 cells I can use!

Last update for a while. I put 5 batts in series and connected it to the laptop, and something must of shorted because it got really hot, but now my laptop isn't charging. So I'm gonna have to send off my laptop that I haven't even been using for a month to service and go back to my crappy...

That's awesome! How long does it run? What buck converter does it use?

Another update! (Oh boy) Forgot I bought these. These are 18650 cell tabs (I call them leads). There's more than shown here, but this is how much I'd need for this project. (15 - and 15 +). [/URL] I've got the proper holder hereand I'll be printing out 15 of the single holders and...

Plan 2 was to use 3 batteries in series to series connect to 2 other batteries in series so I had 5 batteries in series, providing a good voltage range. While this is providing a good voltage, it's still only 2,150mAh, which isn't enough to sustain a, say, 6A power flow. I only have 13 of these...

Quick update: 5 cells won't work too well, I've figured out. I put 5 cells in series (without a holder) and it's not outputting enough amperage (I think). I'm not sure the cells were full, but this laptop is a bit picky when it comes to amperage. If the amperage is too low, it starts cycling...

I'll check it out, thank you for the pointer!

I'm new here, it seemed like the best place to put it :)

I've got a Model S Performance, the new one. It's bonkers quick but unbelievably practical at the same time. And it's the smoothest driving out of all the cars we own. just a lovely car all around!

I wonder how many blokes have come on this forum to post about their portable battery packs for laptops. Anyways, I've been playing around with making a spare battery to connect to the charge port of my Asus N56JN, the battery on it only holds ~50Wh max, and there's been some wear on my...
