How can I use this to charge a battery pack (a bunch of 18650s)? I don't understand the instructions.

Negative. You would require a way to monitor cell voltage if the 18650 were not individually charged kind of like an rc lipo with the balance plugs. Check out the arduino as a charge controller in conjunction with this boost buck.

Yes, that is what I used. Works great. Need an adapter port for like in a cigarette lighter on the battery pack.

It charges both style of batteries. I have charged my 7.2v 1100mah, 7.2v 1600mah battery and my 8.4v 1600mah NIMH and it did the job with no problems. if it will do those it will charge yours just fine. I have had mine for a year and it still works.

on the battery pack there is little rubber piece. pull it out and plug the charger in. careful not to lose the little rubber piece.

If your measuring the voltage of a battery (18650) with this module it becomes more tricky. The battery is only 3.7 volt. The module requires 4.5-30v supply voltage. You would have to have a separate supply to power the module with at least 4.5 volts, and then measure the battery voltage (with the third wire).If your testing voltages on a battery buy a multimeter. I use this module on a variable power supply to measure the output voltage

Kelly, the charger works with 18650 batteries only, so, also you can measure the length and the thickness of yours batteries then if you have some 18650 to compare the size, then you will be ok.

NO. This charges 1.2 volt NiCad and NiMH batteries. 18650s are 3.7 volts. They look like larger versions of AA/AAA, but that is the end of the similarity. I've had this page bookmarked for a LONG time, and it should give you plenty of info about 18650 chargers: http://www.lygte-info.dk/info/indexBatteriesAndChargers%20UK.html

Sorry, I don't know enough about milliamperes and the science of charging. I used it for numerous different proprietary camera batteries, an emergency radio as well as aa and aaa batteries.

Hey there =), Neither, the 18650 3.7V is its own type battery. It is used for certain devices and i use them to power my Cree Flashlight.

It is made for 9.6 NiMh volt batteries and charges them very well. I'm not sure if it will work with the same desired results for Lithium batteries. You may need a charger just for Lithiums.

First, thanks to Kevin for telling us that the adapter is a 12volt adapter (from the label). I just want to add that my battery pack - as I suspected - outputs 9 volts; the six AA batteries are indeed in series. Therefore, I suspect anything from 9-12 volts should work. Also worth noting is that when my batteries died the other day, I just rotated them and am getting some more use out of them; I expect to have a power source fabricated by the time I need to replace the batteries.

It takes about 2 hours to charge a 18650 battery. About the flashlight--- I paid for it with credit card and it was never delivered !! I cannot help youthere----sorry. Sincerely Don Biddix

Same as others. I used this in my 18650 gadget and it worked flawlessly the first time. Hope that helps.

You can use AA or AAA NiMH rechargeable batteries, it holds 8, they go in positive top, negative bottom, like the pictogram on the charger... Plug it in, I leave mine plugged in all the time, have since I bought it, no problems. Just put your batteries in it, and the indicator on the screen below will show the batteries charge level and it will start charging, when it is no longer flashing, your battery is full. Nothing else required that is it.

Sorry, I misunderstood your first post. Are you using this battery pack to charge rechargeable batteries, such as AAs or AAAs?

I am not sure what model of charger you have but basically plug it directly in where you would use other charging leads and set it to 1S lipo and charge
