Turnigy i10 battery mod ( 18650 )

It was time to mod my i10 and replace the factory battery with a 18650 ... Been thinking about how to do this mod for a while ..

So the plan was to put in a single 18650 / single battery carrier .

First thing is to open the case ...
Remove the 4 screws you can see ,
Then remove the rubber grips on the side of the case
You will now see two more screws that need removal to open the case ..

Now open carefully , the USB port / PC board , needs to be removed / unscrewed ...

Cut the red and black wires going to the battery bay as near the bay as possible ...

Now you have free access to the back of the case ...

Cut and fit the battery carrier ..
Fit the battery cover on , put a 18650 in the battery carrier and test fit it . then hot glue in place ..

The cover and battery need to be in place for proper fitting when you glue ...

I used hot glue , you can Epoxy after using hot glue .. Just make sure that everything fits and works as it should ...

Once the battery carrier is glued and ok , you can solder the wires to the USB / PC board ... You know , red to red and black to black .
You may wish to use some heat shrink tube ... Slip it on before soldering ...

Now you can re assemble ...
Dont use all the screws , two should be enough
Pop in a 18650 and make sure the Tx turns on ...

If everything is ok , re assemble and be happy ...

I trimmed the battery carrier enough for a flush fit on one side so that I could still put in a SD card .. ( if this is important to you )

Now why did I do what I did ...

A) A single 18650 is a massive upgrade over the factory battery
B) A single battery is safer than dual Li-ion
C) I wanted access to the SD card , to be able to insert and remove
D) Charging options , I can still USB charge , or use a dedicated 18650 charger
E) Changing batteries is easy ( future upgrades or just poping in a fresh battery )
F) The original factory battery just sux's ...

Hi old4570. Nice and easy mod. Just a quick question. I've heard that these batteries can also be charged with a regular lipo battery. Is that true?

Do you mean with regular Lipo charger ..
Then yes ..
the 18650 can be charged where it is VIA USB
Or with a powerbank
Or you can pull it out and throw it into a 18650 charger that the flashlight crowd use ..
Or you can use a hobby charger , as long as you terminate @ 4.2v and don't charge to hard all is good .

Why do you say 1 LI-ion cell is safer then using 2? You could easily fit 2 in there, wire it parallel, so the voltage remains the same, and there you go.

One battery is safer than two ..
I really don't want to explain why , as the explanation is long and tedious and you don't have to take my word for it . Do some research and draw your own conclusion .
