Description

BCPB1+ is a highly reliable Lithium-Ion Battery Charging, Protection, and Balancing Board that operates with wide input range, DC5-19V. This board is able to charge batteries with input voltage above, below, or equal to the output voltage. It is designed for 2 in series 26650 Lithium-Ion Batteries that provide approximately 30-40Wh energy. The integrated MPPT charging feature supports a 19-24V power supply. BCPB1+ is complemented with a visualized display of battery level indicators. To ensure the reliability of this board, it is equipped with full protection circuit, Cycle-by-cycle over current protection, over-temperature, short circuit, and over/under voltage protection. The battery balancing IC keeps constant battery voltage between 2 in series 26650 Lithium-Ion cells. It is designed for industrial application with verified MTBF for low-temperature increment under rigorous design.

Specifications typical @ +25℃ unless otherwise noted. Specifications subject to change without notice.
Parameters Conditions Min. Typ. Max. Units
Supply Voltage Both wide input range, Type-C Jack (J13) and JST-PH(J7). 5.0 - 19.0 VDC
Solar panel input,Molex Micro-Fit(J2 ) through a diode. 14.0 19.0 24.0 VDC
Supply Current Supply current at both wide input range,Type-C Jack (J13) and JST-PH(J7)are limited by boost circuit only, so typical current limitations are same. 0.8 1.5 2.1 A
Output Current USB Type-A Jack (J14).  - 2.0 3.0 A
Molex Micro-Fit (J6). - 2.0 3.0 A
Charge current Pre-charge current (0-140mA) might take hours before going to constant current charge mode at 1.5A typical. The charging current decreases dramatically after reaching constant voltage mode which start at 4.2V. The maximum charge current can only be obtained if Iin: 2.1A, Vin: 7.5V are supplied to the board. Charge current decreases if lower input current and voltage applied to the board. 1.5 – 15% 1.5 1.5 + 15% A
Battery Capacity Use 5000mAh to get the typical value. Refer battery’s user manual   if you are using your own battery. 5000mAh 26650 Lithium-Ion Battery
Overcharge Detection Voltage (per cell) Once overcharge triggered, users are supposed to wait till voltage drops to over voltage release voltage and activate again for normal use. 4.19 4.24 4.29 V
Overcharge Release Voltage (per cell) 4.00 4.05 4.10 V
Over-Discharge Detection Voltage (per cell) Power up this board through Type-C Jack (J13) or JST-PH(J7) to activate if the board goes into protection mode or for initial use. 2.72 2.80 2.88 V
Over-Discharge Release Voltage 2.90 3.00 3.10 V
Operating Temperature For wide operation range version, please contact us for solutions. 0 20 50
