    charging 4 pcs. 18650 in parallel

    Not really they will charge pretty evenly when in series. Especially in a S2 configuration. When you go over 2 batteries in series is when you want to balance them for sure. When i did RC airplanes I had S4 li po packs the charger was separate from the balancer. So i would charge the batteries...

    Canabalizing 510 Batteries for Connectors? Point me to a Tutorial?

    I usually use a dremel with a diamond blade and slice the case long ways and pry the case open with a small sharp screw driver. A easyer way for most ( but can be hard on the connector threads ) is to have a threaded rod and screw it in and use a circular motion to loosen the connector and just...

    charging 4 pcs. 18650 in parallel

    :vapor: I smell smoke not vapor .......:vapor: The problem is trying to charge batteries set up to charge( parallel ) @ 3.7 volts @ 7.4 volts ( nominal voltages ) It could work out if you did a hybrid config and ran 2 batteries in series and a the other 2 in series separate from...

    can i use these voltage indicators??

    It has circuit protection so you wont fry it hooking it up like that. You need to hook the negative into any ground available then you hook a positive into your line going to the atomizer. After the switch so it is not always on. If for some reason your switching the negative side then what i...

    PTN04050CAD Laser Toner Transfer PCB

    No dont have a box to put it in. Besides that these cheap China batteries i got wont run the thing without cutting out. I have been power it off a evercool chip for testing. the 200k pot really doesnt make to big a difference maybe a .5 or .6 of a volt lower. running a 10k with the pot works out...

    Please help me find directions to make a VV mod

    It will actually add run time about 1/3 With the evercool chip. Since you are bucking down with a very effiecent switching regulator. 1600mah at 4.2 volts is not the same as 1600 mah at 12.6 volts. There is a lot more watts is the 1600 12.6 volts. If you put a amp meter on the 12 volt input and...

    Where to get PCB's made

    Yeah the guy that used that kit in his is making parts out of aluminum. Really i plan on using this for a lot more then PCB's. Got all kinds of ideas in my head. But it for sure will make my life easyer building what i have planned. I just have a drill press right now with a mill vise and it is...

    Where to get PCB's made

    Thanks for putting this idea in my head i been doing nothing but research since. Thinking i might go with a Momus design since it is ridged and strong enough to Cut aluminum. But also accurate enough to do PCB's . Going to cost about 800 to 900 bucks to build I figure. Thats for everything...

    Which is better?

    I must point this out. No one really vapes directly off two stacked batteries or 7.4 volts. Just about everyone will slap a regulator on the 7.4 and take it down to at least 5 volts. Better yet they will go VV with so they can adjust the voltage. Now with a linear reg it will be burning up alot...
