Lithium-ion and lithium-polymer batteries should be kept at charge levels between 30 and 70 % at all times. Full charge/discharge cycles should be avoided if possible.
Similarly, charging your battery before you dip too much below 20% isn''t just about peace of mind; it can also contribute to better battery health. Lithium-ion batteries perform less efficiently at low states of charge, and they perform better over the long term when they are only partially re-charged each cycle. So going from a 20 to an 80% ...

Charging Current: It is crucial to charge LiFePO4 batteries at a current that aligns with the manufacturer''s recommendations. Charging at a higher current than specified can lead to excessive heat generation and reduce the battery''s lifespan. Following the recommended charging current helps maintain the battery''s performance and longevity.
Unlike most other battery types (especially lead acid), lithium-ion batteries do not like being stored at high charge levels. Charging and then storing them above 80% hastens capacity loss.
As a rule of thumb small li-ion or li-poly batteries can be charged and discharged at around 1C. "C" is a unit of measure for current equal to the cell capacity divided by one hour; so for a 200mAh battery, 1C is 200mA. Example: common 402025 150mAh battery from Adafruit: quick charge 1C, maximum continuous discharge 1C.. Slower charge and discharge eg 0.5C or 0.2C gives …
