Description

As the new comer of BCPB (Battery Charging and Protection Board) series, BCPB4 inherits the high efficiency and high reliability of BCPB2, offering more battery holders and larger capacity. BCPB4 is designed for 5pieces 26650 Lithium Batteries in series and can be used as a power bank for Routers, Raspberry Pi, High power portable speakers and Mobile phones, which is widely used in Home DIY applications to save your precious time from the connection of electric wires. Supporting wide range of charging input voltage and hybrid charging sources is one of the highlights of BCPB4. Any 5-24V 2A adapters can be used to charge the batteries with BCPB4.

This board can be powered by multiple chemical components of rechargeable batteries like Lithium-ion battery, Lithium-iron phosphate battery, Ni-MH battery, Li-Fe-Po battery and Lead-acid battery. Besides that, the balance and protection circuit constantly to monitor each cell’s voltage, the current of charging or discharging, and the temperature of the environment to provide overcharge, over-discharge, output over-current, short circuit, charge over-current and over-temperature protections, etc.

can you disable discharge while charging? i want to use with jab5 but when using while charging i only want to draw current from external power supply.

Hi. There is no switch on BCPB4 to disable discharging. Have a nice day~

Great board! Currently using this with the recommended BCPB/DC Input Conversion Board. Planning on adding a switch to the BCPB/DC, as it drains the batteries too quickly. Is there a method to add a second BCPB4 to the original, to increase capacity? Would adding a 2nd one in parallel be recommended/feasible?

Hi, Eder. Thank you for your kind feedback on our product. You can connect more than one of same model battery boards in parallel for higher battery capacity and longer use time. The batteries boards need to be connected one by one. Besides, before connection, please make sure voltage difference between two boards is less than 1V. Wish this could help you. Have a nice day~

Hello, I would like to use the board to power a motor controller. During braking there will be reverse current due to back EMF. Does the board support reverse current from the power ports? I.e. does it support energy recovery? Thanks

Hi, Ioannis. Thank you for your interest in our products. BCPB4 doesn't support energy recovery. In addition, please note that the output connects directly with the batteries, therefore, if the voltage of the reverse current is higher than battery voltage, battery board will stop discharge and begin to be charged. Have a nice day~

Hello. My question is about the connectors for external controls. J20=LED Indicators port: Circuit 1 = Power. Which voltage does this pin supply? Circuit 3/4/5/6 = LED4/LED3/LED2/LED1. Is there an internal resistor included on the board or do I have to add an external one? J1=LED Indicator for external charging port: Circuit 1 = LED+. Which voltage does this pin supply? Circuit 2 = LED-. Is there an internal resistor included on the board or do I have to add an external one? J19=LED Indicator for external power port: Circuit 1 = LED+. Which voltage does this pin supply? Circuit 2 = LED-. Is there an internal resistor included on the board or do I have to add an external one? Thanks!

Hello, Korbinian. J20 1. This pin (Circuit 1) delivers output voltage of the battery board. 2. Pin 3, 4, 5 & 6 are all connected with a 1k resistor in series. J1 & J19 1. Circuit 1 delivers charging voltage. 2. Circuit 2 is connected with a 7.5k resistor in series. Wish this could help you. Have a nice day~

Hello Wondom, i'm working with the BCPB4 for a mobile soundsystem. For the 26650 Lithium-ion batteries do you recommend to use protected or un-protected or IMR batteries ? Thanks for your attention. Jerome

Hi, Jerome. Thank you for your interest in our product. The normal 26650 Lithium batteries would be fine because there's full protection circuit equipped on BCPB4. Wish this could help you. Have a nice day~

Hello, can this battery board be used to power amplifiers from another brand, if the input voltage of the amp is respected ? Tanks

Hello, Ewen. Thank you for your interest in our products. As long as voltage is suitable and the power of the amplifier board is within 100W, you can use BCPB4 to power the amplifier board. Wish this could help you.

I have a 24V, 5A AC/DC power switch adapter. Will this work with this board, or should i find a 24V, 2A one? Which will you recommend?

Hi, Eder. Yes, you can use the 24V, 5A AC/DC power switch adapter to charge the BCPB4. Any power adapter whose voltage is within the recommended range and current is larger than 2A can be used to charge BCPB4. Wish this could help you.

After a couple days the board no longer provides power on VBAT and GND (only about 0.3V). The batteries are fully charged (4.15V each). If I apply charge voltage to VCC and GND then then VBAT and GND will provide power. Is there any way to turn on device without starting charge again?

Hello, Andy. If the batteries are re-installed or they enter into over discharge protection (2.8V), you need to connect the board with the power supply to activate it. After activation, you can disconnect with the power supply. If there is still a problem, please send a picture or a video to store@sure-electronics.com so that we can help you solve it. Wish this could help you.

What type of connector is used on connectors J1, J2 and J7? It does not say in the data-sheet. It looks like PH 2mm 6POS and PH 2mm 2POS. Can you please confirm this?

Hi, Joachim. Thank you for your interest in our products. Yes. The connector used for J1 and J2 is PH-2POS-2mm. The connector used for J7 is PH-6POS-2mm. Wish this could help you.

Hi, what advice do you have to charge this via solar panels? I have a 40w panel connected to the correct input and the voltage of the PV panels drop immediately below 2 volts. Why does it not find the maximum power point as described? Look forward to advice and help. Thanks.

Hi, finn. The BCPB4 can be charged by solar panel but please be note that MPPT charging circuit is not equipped in the BCPB4. The voltage of the solar panel should be within the power supply range as 5-24V of BCPB4 and the effective output current of the solar panel should be more than 2A. It may take long time for it to be fully charged using solar panel. Wish this could help you.

Hi, I have questions about two different possible setups using this board. Firstly, could this board be used to power the following (all at the same time): AA-AB32971 T-Amp + AA-AB41136 Bluetooth Receiver + AA-AP23122 DSP? And secondly, could it be used to power: AA-JA32172 Amp Board with DSP + AA-AB41136 Bluetooth Receiver? Many thanks. Andreas

Hi, Andreas. Thank you for your interest in our products. Please kindly be noted that the output voltage of BCPB4 is up to the batteries voltage. The power supply of AA-AB41136 - BRB3 is DC9V-15V and the power supply of AA-AP23122 - APM2 is DC5V. Therefore, BCPB4 cannot be used to power the two boards directly. Considering your requirements, we recommend you to order JAB2 and JAB3, which can build a 2.1/4.0 audio system integrated with both Bluetooth and DSP. What's more, you can use BCPB4 to power the two boards at the same time. Wish this could help you.

Hi, I would like to use this module to power JAB3, plus I need a second 5V 1A power supply, is it possible to have this second power supply directly from the SKUPS-BC12113 without using SKUAA-JA11112?

Hi, Enrico. Thank you for your interest in our products. We have released a BCPB/DC Input Conversion Board W BC1.2 USB Charging Port (PS-BC12211) that can be connected with BCPB4 through J28 on BCPB4 to provide a maximum output of 5.25V/2.1A. Please kindly refer to the following link. http://store.sure-electronics.com/product/PS-BC12211 Wish this could help you.

Can I use solar panel with this? IE for boombox... listen and charge at same time?

Hi, james. Thank you for your interest in our products. The BCPB4 can be charged by solar panel but please be noticed that MPPT function is not equipped in the BCPB4. The voltage of the solar panel should be within the power supply range as 5-24V of BCPB4 and the effective output current of the solar panel should be more than 2A. It may take long time for it to be fully charged using solar panel. The BCPB4 can charge and discharge at the same time. Wish this could help you.
