Main Technical Specifications - JK B1A8S20P User Manual

1 Overview
Li-ion battery intelligent BMS is a management system tailored for large-capacity series Li-ion battery
pack, with functions of voltage acquisition, high-current active balancing, over-charge, over-discharge,
over-current and over-temperature protection, coulomb meter, Bluetooth communication, GPS remote,
etc. It can be applied to Li-ion, lithium iron phosphate (LiFePO4), LTO and other battery types.
JK BMS relies on the energy transfer type active balancing technology with independent intellectual
property rights, which can achieve a maximum continuous 2A balancing current.
The high-current active balancing technology can maximize battery consistency, improve battery
range and slow down battery aging.
JK BMS has smart Android and IOS APPs. APP can be connected to the BMS via Bluetooth to check
the working status of the battery, modify the working parameters of the board, control the charging
and discharging switches, etc. JK BMS is small in size, simple to operate and full-featured, and can be
widely used in small sightseeing vehicles, mobility scooters, shared cars, high-power energy storage,
base stations, backup power, solar power plants, etc.
