Description This is an active BMS, it supports 13S-24S Li-ion and 15S-24S LiFePo4 Continuous current of A It also has active equalization current 2A You can set equalization voltage and charge and discharge protection parameter through APP Can display the battery voltage single series After connecting the BMS, please use the power supply which is 5v higher than the battery voltage to activate it. Product character 1. Active balance functionality, lose battery capacity no need to balance sales voltage difference, increase battery use efficiency for 95% 2. It has the protections of overcharging/overdischarging/overcurrent and short circuit, etc. 3. Single battery series voltage range is 1~5V, accuracy is 5mV 4. With coulomb meter function, the remaining power is very clear 5. BT communication function, battery status can be displayed on APP 6.RS486 and can be customized Balanced Shape: Active EQ Active equalization current: 2A Internal resistance: MΩ Rated discharge current: A Maximum discharge current: A Over Current Protection (adjustable): 10-200A Wiring method: common port Monomer voltage range: 1V-5V Voltage acquisition accuracy: ± 5mV Battery cell overcharge protection voltage: 1.2V-4.35V (adjustable) Battery cell overcharge protection recovery voltage: 1.2V-4.35V (adjustable) : 2-120S (adjustable) Battery cell over discharge protection voltage: 1.2V-4.35V (adjustable) Battery cell over-discharge protection recovery voltage: 1.2V-4.35V (adjustable) Temperature detection quantity: 3 pieces temperature: -20~70℃ Power requirements: 24V ~ 100V, can be powered by battery or external power supply Power dissipation: balanced: 10mA and 100V, unbalanced: 6mA and 100V Download Link - IOS: Search (Seeds of JIKONG Camera BMS) in APP Store Android download link:https://www.pgyer.com/Cfq3 Instructions:https://github.com/NEEY-electronic/JK/tree/JK-BMS BMS protocol to connect to other devices: https://github.com/syssi/esphome-jk-bms VenusOS Driver: https://github.com/Louisvdw/dbus-serialbattery Package including: 1*JK smart bms (Built-in Bluetooth) 1*Cable 1*Temperature Sensor
