This FY•X high quality 20S 24S 60V 72V 75A smart BMS for Battery Rental Replacement is a BMS specially designed by Huizhou Feiyu New Energy Technology Co., Ltd. for electric bicycle battery packs in the rental market. It is suitable for 20-cell lithium batteries with different chemical properties, such as lithium ion, lithium polymer, lithium iron phosphate, etc.

The BMS is equipped with a GPRS module, which can promptly report the battery pack positioning information and the corresponding voltage, current, temperature, and protection status information of the battery pack. It supports powerful functions such as remote lossless upgrade of firmware and remote locking of the battery pack.

It has a CAN communication interface that can be used to set various protection voltage, current, temperature and other parameters, which is very flexible. And the charging cabinet is identified through CAN communication. Non-designated charging cabinets cannot charge the battery pack normally. The charging cabinet is supported to upgrade the firmware function of the BMS through CAN communication without loss. The protection board has strong load capacity and the maximum sustainable discharge current can reach 75A.
