13S 48V 18A Common Port BMS Battery Management System PCM PCBA for 18650 Lithium Ion Battery Pack with Balance, heatsink, Waterproof (18A)

Product description:

• Use top quality (A-level) protective integrated circuit IC, from the solution of Japan.
• Strong load ability, constant discharge current, use high voltage resistance, low inner resistance power Mosfet. The heat sink will greatly help to cool.
• IC itself has a power balancing function. The circuit is simple and reliable.
• Typical voltage detection for each cell. So each battery will be prevented over charged or over-discharged.
