Hi! I need good rechargeable battery for my wireless project (Pro mini+high power nrf2401+IR diode). To be 100% sure I need about 2500-3000mAh.
For charging I got this charging board.
As a battery I want something like this battery. I need it thin as possible.
On the Ebay there is lot of sh*t - like 18650 UltraFire batteryes promising twice power as Panasonic analog.
What about theese tablet/PDA flat batteryes - are there any trusted brands (like Panasonic or Sony for 18650)?
