bule COVER With BMS and battery cover Already soldered. See actual photos for reference Product parameters:LiFePO4 battery Maximum charging voltage: 3.45V Normal voltage: 3.20V Minimum discharge voltage: 2.20V The battery voltage may drop due to storage time Please do not charge in series. And wrong use of positive and negative charging. This will cause battery cell death. Charge Control: Special batteries for solar lights require a proper charge control system to ensure that the solar panels capture enough solar energy and use it for charging. Charge controllers usually include monitoring and regulating functions for the charging process. Special batteries for solar lights usually use deep cycle batteries. These batteries are designed to be charged and discharged multiple times to adapt to the charging and discharging cycles of the solar system. Popular choices include lead-acid batteries, lithium iron phosphate batteries (LiFePO4), and lithium-ion batteries.
