I have been attempting to create a portable arduino gaming system. While I have tried normal 'AA' or 'AAA' batteries, they are too large, so have decided to use a lipo battery. I now have this, but I would prefer to be able to recharge it without removing the battery, so need a charging board.
I have contemplated using the sparkfun single cell charger with a place for system out power (to the actual device), but it costs much more than I want to spend (it can be found here on Amazon: http://www.amazon.co.uk/LiPoly-Charger-Single-Cell-Input/dp/B004X7TZ9I/ref=sr_1_2?s=electronics&ie=UTF8&qid=1404232239&sr=1-2&keywords=sparkfun+battery+charger). I would like to use a very cheap generic board to charge the 3.7v lipo battery, but my question is: Can I embed this in my project and charge the battery without removing it.
My desired charger board can be found on Amazon here: http://www.amazon.co.uk/Generic-Lithium-Battery-Charging-Charger/dp/B00E39RGME/ref=pd_cp_ce_0
Thank you for any help!
