Hello, I need a good , cheap battery charger and some
help with finding it. The type of charger that I’m looking
for should have/do the following things.
1-Charge battery sizes:18650,14500,16340,26650,10440,etc.
w/battery Chemistries: Li-On, Nimh, Nicad— (all types)
2-Battery Slots—4
3-Charge indicator—test mAHs—charge & discharge etc.
4-Overcharge protection and all the other good stuff.
Help me find what’s out there. Thanks, Mike 
I’ve been passively looking for the exact same thing. However, if it exists, I don’t believe the price would be cheap. So, I’m guessing you will need to make what you want. If you are looking to try to obtain the same results as shown on some of the many graphs here, then I would suggest you check out HKJ’s website, especially the http://lygte-info.dk/info/myLabSetup%20UK.html page, it looks like a goldmine for what to do.
I might consider trying to figure out the circuit boards with a known chip on one of the chargers I have. Then I’d try to tap the data it could give me with an Arduino, and then write a program that listens to the USB com to record that data. I’d do it that way, since I don’t have anything to record data directly with the Arduino at this time. Or it could be simpler to make a something from scratch with Arduino just for testing.
There is a charger that connects via bluetooth to an app. No idea what data the app actually gets or if it’s just for status and settings, but it’s around $90USD. Also if just interested in NIMH batteries, check out http://www.paulallenengineering.com/. They were on kickstarter, and it’s all open-source, might be able to just transition it to Li-ion.
I don't believe there's any charger that does that right now, but there will be soon. SkyRC MC3000. Price range could be anywhere from $50 to over $100. Is that cheap? Show me another charger that can analyze and create graphs 4 batteries simultaneously for less money. The closest thing I can think of is a quartet of Turnigy Reaktors, but you'll need four separate computers for graphing because I've found that multiple instances of Logview don't work well together.
The SkyRc MC3000 looks at least 2-3 months away, but it should have bluetooth for settings and display in an app and a PC-Link to control and monitor your charger via personal computer. I’m going to estimate the USD price as no less than $125, unless the PC-Link gets dropped.
The most info so far about it seems to come from this link:
If I am reading the OP correctly he doesn’t need data logging with graphs etc. I would suggest the Opus BTC-3100 V2.1 from Gearbest on special for $42 at the moment.
I would swear the OP edited his original post. I know I want data logging, and I could have superimposed my want on his request, but I don’t believe I did.
I would fully concur that at the choice of the above poster at this time. I have one on it’s way to me. $42 is a great price, but it won’t be fast shipping. If you have someone you could gift or sell one to as well, buy two and the hopefully faster shipping is really cheap. You must use the coupon in the gearbest post in this forum to get the $42 price.
I could have sworn that post said that graphs were wanted, which would only be possible with that MC3000. Maybe I'm mistaken, but either way that requirement is gone, which makes the BT-C3100 is the best choice.
To all who are trying to help. You are correct.
Yes, I did edit the OP. My mistake ,wrong wording.
What I meant by graphs was really something
showing the charging voltage of the batteries.
Also, I’m not mechanically inclined so I can’t build
anything. Sorry for the mistakes.

Hey leaftye try vmware… The more memory the better but you can run as many terminals as you want if your a windows guy. In linux you don’t need to do that though, like through ssh- use the screen command to create virtual terminals within the same vm and nohup to keep things running in the background
If I get a faster computer, I'll give that a shot. Right now everything I have is very slow. I've tried running vm's on my fastest computer, but it was painfully slow. Logview would have issues if it were running that slow. It's a good idea, I just don't have the hardware to make it feasible.
