I need to change the battery to a Li-PO One, 3.7v, so in this case it will be a problem to put it straight to VCC, maybe I will recharge it directly through a Li-PO charger, when the battery is still connected to the system. There will be like 4V, which is not good for BMP085 Sensor or for the Ftdi chip with 3V3. Is write in this case?
Thank you,
Razvan
