Hello everybody, has anyone used the coin cell battery CR2477 for your lilypad projects?
I donĀ“t know if this battery is suitable for the lilypad. CR2477 has about 1000mA and 3 V and in my project i need to control a lot of Leds so in my case the normal coin cell battery CR2032 may be is not enough.

1000mAh = capacity of the battery
It means:

Capacity[mAh] = I_batt[mA] * time[hours]

Example:
Current consumption of your lilypad system (inclusive LEDs) I_batt = 20mA
Capacity of your battery = 1000mAh
Time of lilypad operation = Capacity / I_batt = 1000mAh / 20mA = 50 hours.
