BMS Module 13S 48V 35A- 13S Packet Charging / Discharging Protection BMS modules protect 18650 cells against excessive discharge and overcharging in the charging process, BMS allows you to charge the package without the use of special chargers Each of the cells in the package affects the operation of the BMS module, if the voltage on any of them drops below 2.5V, the system will prevent further discharge of the package (discharging the cells below 2V significantly shortens their life) In the case of charging, the BMS will also prevent any of the cells from being overcharged (in the case of Li-ion cells, overcharging the cell may result in its unsealing and, as a result, its ignition, which may cause a fire). That is why the use of BMS systems is necessary for the correct and safe use of the packages Li-ion 18650 cells. BMS disconnects the charging process when any of the cells exceeds the voltage value of 4.250.05V Over charge protection: 4.250.05V (per cell) Over discharge protection: 2.550.08V (per cell) Charging voltage: 54.6VDC Average operating range: 36.4V - 54.6V Continuous discharge current: 35A Continuous charging current: 6A Current overload protection Short-circuit protection Resistance: 20m The module has a built-in BALANSER PH2.0 14pin connector Operating temperature: from -30 to 80 Dimensions: 70mm x 52mm x 9mm Included: module plug with wires Do not mix new and used cells. It is best to use cells with the same parameters of voltage, capacity and internal resistance. In the section attachments, downloads, specification and connection instructions in English.
