1. If you want to buy our 0.5W specifications of the battery cell back to DIY to your hand battery charging, if it is for 3.7V/2000MAH lithium battery charging, you need to 3 series,

 in the premise of full sunlight theoretically full of batteries to you need 8 hours, if you need to fill the time faster, you can buy 6 pieces, 

 3 pieces in series and then connected in parallel on the other 3 pieces in series, referred to as the 3 string 2 parallel, so that charging time can be shortened by half, as long as 4 hours or so.

2. Of course, you must have a certain basic knowledge of electrical engineering and simple mathematical calculations and hands-on ability, and have the relevant tools, such as soldering iron, multimeter, etc., 

  Note: DIY battery cells do not have overcharge or overcurrent protection.

3. If necessary, you'd better need to buy another professional solar controller and lithium battery protection board.

4.This product does not include installation instructions, recommended for professionals!
