Added RS232 port, allowing for external devices to read out the data from the BMS. Additional Information on the data is located here: http://chargery.com/uploadFiles/bms24_additional_protocol%20V1.22.pdf For same Battery positive and negative terminal when charge and discharge, BMS24T can control charge and discharge separately. -
Page 4: Order Information
The BMS24T can be used with any lithium battery charger, when any cell is over charged, the BMS24T will open the charge relay to cut off charge, if used with a CHARGERY charger, the charge control is handled by connecting the CHARGERY charger to the BMS24T on COM1, when any cell reach OVP, the charge current will decrease automatically to prevent any cell damage. -
