Finalization of the Chinese player

Music lovers are well aware of the cheapest Chinese player. The sound and power are above average, comfortable and compact. But the biggest trouble is the player’s battery life, which is built into it. After charging, it lasts less than 30 minutes at medium power. This is extremely unpleasant. I decided to fix this problem. I took one element from the battery pack from the ASUS laptop; according to the voltage parameters, it went well 3.8-4 V, which corresponds to the player's parameters. I disassembled the player (see photo) and unsoldered its native battery.

Lengthened and soldered two new wiring, connected a new battery. Now the sound time has increased from 8 to 12 hours with more power. Since autonomous charging of the player has now become ineffective due to the large capacity of the new battery, I had to modify the battery a bit. I made a conclusion for charging it from the telephone power supply to the line. Cut off the plug, and in his place soldered mini "crocodiles." the battery charges for 10-15 minutes and you need to monitor to prevent the battery from heating. I spoiled one element - it overheated and it failed. Of course it turned out a bit clumsy - not a company, but now you can listen to music as much as you like.
