Walking Polution Monitors

Looking for a Laptop - Austin Clark

Padre's Picks

Batteries - Bostjan Cadej

The IDEAL voltage to store you backs for a long time is 3.85 volts. (50%)
Also... if you store the LiPo pack when full, it will lose between 2-4% of its charge per month. If you store the LiPo pack at 50%, it will lose less than 1% of its charge per month.
It is EXTREMELY important that the voltage in a LiPoly pack not fall below 3.0 or go above 4.2 -- That will damage the cell.
