Wiring phone battery directly to PowerBoost
Wiring phone battery directly to PowerBoost
Hey all, so I've seen that many people have said that they have soldered wires directly to the phone battery pads and to the power boost (while of course accepting the risk of an exploding battery lol). What I am confused however is what and where I solder the two wires to the power boost.
This is the power boost I have
https://www.adafruit.com/product/2465
The black casing is where the plug would go if the battery had one, but where would I solder the wires directly too?
Thanks for any help!

Re: Wiring phone battery directly to PowerBoost
If you don't want to use the Powerboost's JST connector (the black plug), you could remove it and solder wires directly there.
My recommendation instead: get some wires with a jst connector on one end (Adafruit sells these), solder them to your battery, and then have an easy/safe disconnect from the Powerboost if you ever need it.

Re: Wiring phone battery directly to PowerBoost
Has anyone done this? Most phone batteries have 4 pads, I'm assuming 2 are + and 2 are - ?
If this is correct im also assuming you only need to solder onto one of each??

Re: Wiring phone battery directly to PowerBoost
Usually, original phone batteries have 3 or 4 pins, which are +, -, a sensor and a resistor. Most common 3rd pin is a temperature sensor, and the 4th is a resistor. The temperature sensor measures,,,, well, the temperature. so when it gets really hot the smarphone shuts down. The resistor on the other hand has variable values, so that the phone "knows" if the battery is original or not. (usually Chinese batteries don't have none of this sensors). Nokia has that habit of putting a certain resistor on batteries. hope it helpsLphillimore wrote:Has anyone done this? Most phone batteries have 4 pads, I'm assuming 2 are + and 2 are - ?

Re: Wiring phone battery directly to PowerBoost
@correia5022 Yep makes perfect sense, thanks. Will look to identify the + and - only when I solder

Try and error using a multimeter.Lphillimore wrote:@correia5022 Yep makes perfect sense, thanks. Will look to identify the + and - only when I solder
usually the + and - are the ends of the pins, so the 3rd pin (and the 4th) are in the middle.. (i think 99% of the batteries are like that)

Be careful, I remember reading that soldering directly to the phone battery was risky.Lphillimore wrote:@correia5022 Yep makes perfect sense, thanks. Will look to identify the + and - only when I solder

Re: Wiring phone battery directly to PowerBoost
I've been running an Anker 3100mah note 2 battery for a few months now with no issues. I've even left it charging over night without issues. As for the soldering, just prep the battery pad with solder 1st then tin the wire and should not need too much heat/time to attach the 2 together.
