3S 25A BMS Battery Protection Board

3S 25A BMS Battery Protection Board is available from United Electronics. Review the listed specifications and contact us to confirm the exact model and current quotation.

BMS Battery Protection Board 3S 25A 11.1V 12.6V 18650 AA AAA Lipo Li-ion Lithium Battery
This is 3S 12V 25A 18650 Lithium Battery Protection Board 11.1V 12.6V High Current With Balanced Circuit Over Charge Over-Discharge Over Current And Short Circuit Protection Function. Board charging and discharging are the same port, the board includes the balanced circuit.
When the charge balance, the board will be a bit warm, even after disconnecting the charger, some are still in the balance, will continue to warm for a while until below the equilibrium break threshold.
The protection board cannot be used for iron lithium polymer battery (for other batteries, no matter what material, as long as the overvoltage and put voltage can be used for cutting), electric finish machinery, electric bicycle batteries, car, and motorcycle starter battery protection.
Applicable to the following products (within rated power):
Electric drill, 775 motors (6A-10A), small power inverter, small power vacuum massager battery, LED lamp, 12V standby power electronic products, 12V120W car washing pump, battery, solar street lamp monitoring standby power supply, and other products.

BM: Connect to the battery 1 and battery 2 joining point
P+ : Connect to the charge / discharge side of the positive terminal
P- : Connect to the charge / discharge side of the negative terminal
Precautions:
Strictly according to the diagram wiring: 0V(B-)3.7V(B1)7.4V(B2)11.1V(B+), Do not deliberately short circuit.
After the line is connected, Need to charge first, then have output.
When the battery is connected in series with 3 groups, Please ensure that the voltage of each battery is the same. If not same, please fill in each set of batteries and then use.
Do not mix the good battery and the battery.
The capacity of the battery internal resistance is closer will be better.
Attention: Do not mix the good battery and poor battery to use. The internal resistance of 3 battery capacity are closer will be better. Please buyers know the professional knowledge of this module before buying

Selection and ordering guidance

When comparing 3S 25A BMS Battery Protection Board, confirm the exact product configuration, quantity and installation requirements. Review the specifications on this page together with the supplied model’s documentation. A project quotation should identify the offered model, delivery scope and warranty terms so that different offers can be compared consistently.

What should a quotation include?

Send the required quantity, delivery location and application details to United Electronics. If installation or additional accessories are required, request these as separate line items. For a replacement product, provide the existing model details and connection or mounting requirements. Availability and the current price should be confirmed before placing the order.

How should this product be selected?

Match the battery or protection component to the system voltage, battery chemistry and current requirements. Confirm charging and discharge limits for the exact model; capacity alone does not establish compatibility. For battery banks or replacement installations, check the manufacturer’s instructions before connecting equipment.

Where can I compare related products?

See our 10A MPPT Solar Charge Controller in Bangladesh for related charging options. Compatibility must be confirmed for the exact combination; a related listing is not a guarantee that the products can be used together.

For general renewable energy information in Bangladesh, visit the Sustainable and Renewable Energy Development Authority (SREDA). This general resource does not certify the product or replace its technical documentation.

3S 25A BMS Battery Protection Board: Battery Compatibility

The 3S 25A BMS Battery Protection Board in this listing is described for a three-cell series lithium-ion pack with 11.1V nominal voltage and 12.6V charging voltage. Confirm the cell chemistry and the supplied board revision before assembly. A board intended for this lithium-ion configuration should not be assumed compatible with a LiFePO4 pack.

3S 25A BMS Battery Protection Board: Charging and Load Selection

Use the supplied technical information to match the charger, cells and connected load. A protection board is not a substitute for a charger matched to the battery chemistry. Check continuous and peak current requirements together with cable size, connections and the conditions under which the board will operate.

Ordering a 3S 25A BMS Battery Protection Board

Send the required quantity, battery configuration and intended application when requesting a quotation. Ask for the terminal diagram and confirm the protection and balancing functions of the exact board supplied. Keep the board documentation with the completed battery pack for future maintenance.
