WONDOM 5S 26650 Quick Start Manual

Battery Charging and Protection Series
5S 26650 Lithium-Ion Battery Charging,
Protection and Balancing Board
w MPPT – BCPB4 (PS-BC12113)

Overview:

BCPB4 is a highly reliable Lithium-Ion Battery Charging, Protection, and Balancing Board that operates with wide input range, 5-24V.
This board able to charge the batteries from input voltages above, below, or equal to the output voltages. It is designed for 5 in series
26650 Lithium-Ion Battery which provides approximately 90-125Wh energy. The MPPT charging integrated feature supports a 15-24V
power supply. BCPB4 is complemented with a visualized display of battery level indicators. To ensure the reliability of this board, it is
equipped with full protection circuit; overcurrent, over-temperature, short circuit, and over/under voltage protection. The battery
balancing IC allows constant battery voltage between 5 in series 26650 Lithium-Ion cells. It is designed for industrial application with
verified MTBF for low-temperature increment under rigorous design.
Distributors:

Note: All the components in the block diagram are grounded except Charging LED for External Port
(J1) and LED Display for External Port (J20). Lithium-Ion Cells are connected to battery protection
i
and balance circuit and then grounded. All the Power Output, including the battery level indication
module will be disconnected once the board goes into a protection mode. When the battery is fully
c
charged, the voltage across the charging LED shunt resistor is approximately 28V and drops
drastically to 0V when there is no power supplied to the board.

Notes:

s
1. Sure Electronics does not provide technical support for any behavior of connecting the board with power supply
out of the recommended range. Any damage/problem arises due to this, will not be covered by the warranty.
2. Remove battery from the circuit board if it is not use for a long time.
3. For initial charging, it is normal for the board to take longer time to fully charge.
4. If the board goes into a protection mode or the battery has been re-installed, please recharge the board with DC
Input Jack to reactivate.
5. Please check the battery polarity before installation. This board can be used with Lithium-Ion battery ONLY. Other
batteries, including LiFePO4 is prohibited.
6. Please note, this board is prohibited to be connected in parallel or in series.
* A power supply must
be replugged-in for the
BCPB4 to have a power
output after installing or
reinstalling batteries.
