Will the expansion of the lithium polymer battery affect your mechanical design?
Lithium polymer batteries will expand slightly during charging.Will it affect your mechanical design?
Don’t worry about these.
Because all lithium polymer batteries we produce have reasonable tolerances:
Thickness tolerances is ± 0.3mm,
length is ± 1.0mm,
width is ± 0.5mm.
Moreover, the expansion usually only affects the thickness of the battery, and is within our allowable range.This means that the thickness tolerance is ± 0.3mm (the maximum tolerance is ± 0.5mm), which is the expansion range.
Can the lipoly battery be certified for special requirements, such as IEC62133 /MSDS?
Yes, medium and large projects can obtain additional certification, but it takes more time and effort.
Please discuss your personal requirements with your LiPoly battery representative. We will give you various information about specific battery certification
