How to charge the lithium battery and use environment?

       The standard lithium battery charging method is CC / CV. It can be charged with a dedicated charger or DC power supply. When using a charger, the ripple of the charger is as low as possible, generally not higher than 150mV, and the charging voltage is N * 4.2V Non-lithium iron phosphate battery) or N * 3.6V (lithium iron phosphate battery), N is the number of batteries connected in series. For multi-string battery packs, the recommended charging voltage is only 4.15 ~ 4.18V or 3.6V.

       Temperature and humidity. The temperature is generally -20 ~ + 60 ℃, lithium iron phosphate battery -10 ~ + 50 ℃, the charging environment is 0 ~ + 45 ℃, the relative humidity is within 80%, the air pressure is 0.1kPa, the discharge capacity and cycle life of the battery are closely related to the use environment , So we must be clear about the use environment and choose a matching battery for different application environments.
