Lipoly battery Life?
Standard: After 500 cycles, the capacity will be <80%. It will be affected by the situation of discharge/recharge, and battery environment like temperature, humidity.

What is room to swell of lipoly battery?
Lipoly Battery will have a sligh swell in the charging. So it will affects your mechanical design? The answer we gave is that you do not have this worry about these. Because all lipoly battery we produced have reasonable tolerances: Thickness tolerances is ± 0.3mm, length is ± 1.0mm, width is ± 0.5mm. What’s more, the swell usually only affects the thickness of the battery, and it is within our tolerances. It means that thickness tolerances is ± 0.3mm (Maximum tolerances is ± 0.5mm), that is swell range.
