Description
Smart Jiabaida (JBD) 4S 12V 30A Lithium ion with Bluetooth dongle
JBDBT 4S Li-ion 30A
Introduction about this JBD BMS:
This bms is especially for 4S Bluetooth or smart fixed configurations only. Basically it can also be used for any other lithium technologies even if LiFePo4, Lithium Ion, LiPo and Lithium Metal by changing internal parameters after connecting to Bluetooth App or computer. Most important that it is strictly for 4S battery packs only. As a result, that they cannot be used for any other battery pack Configurations.
In the same way all Parameters can be changed Via Bluetooth App or UART USB Connection with PC Monitoring Program .Default setting inside BMS are for lithium-ion batteries.
Over charge and over discharge protection:
The Lithium-ion battery pack will stop charge after the cell voltage reaches 4.25V and stop discharge when its voltage reaches 3V.
Temperature Protection:
- In high temperatures the bms ranges from 70℃ discharging battery protection.
- Meanwhile in low temperatures the bms ranges up to -20℃ battery protection.
What you will get:
- JBD 4S Smart Li-ion 30A rated voltage with 12V BMS
- Balanced wire sense cable (5 Wire sense cable with connector)
- Bluetooth dongle
- Thermostat
- Instruction Manual
- Please use Xiao Xing App for Bluetooth Applications .The link is available in bms batteries website software downloads dropdown box
- This BMS is also used for all kinds of lithium-ion cells including 18650 ,21700,32650 prismatic cells.
