Equilibrium current: 56mA

Size: 60408.5mm

The applicable scope of BMS

3-10S 15A 3V sodium-ion battery protection board, suitable for low-power short-distance small electric vehicles, mainly covering electric bicycles (low-power models), electric scooters, and balance bikes.

The scope of inapplicability of BMS
Not suitable for high-power electric motorcycles, electric tricycles, etc.: These types of vehicles require a greater continuous discharge current (usually > 20A) and a higher voltage. The parameters of this protection board cannot meet these requirements.

Discharge protection current limiting: 40A

Charge continuous current: 10A

Charge protection current limiting: 20A

Overcharge voltage: Single path 3.95V±0.025V

Overcharge discharge voltage: Single path 3.8V±0.05V

Overdischarge voltage: Single path 1.8V±0.03V

Overdischarge discharge voltage: Single path 2.0V±0.1V

Over-temperature protection: -10℃-70℃

Equilibrium current: /

Size: 62509mm

The applicable scope of BMS
5-16S 15A 3V sodium-ion battery protection board, suitable for medium-power short-distance electric transportation vehicles. The core application covers medium-power electric bicycles and entry-level / low-power electric motorcycles.

The scope of inapplicability of BMS：

Not suitable for high-power electric motorcycles / three-wheel vehicles: These types of vehicles usually require a larger continuous discharge current (generally > 15A). This protection board has limited continuous discharge capacity and cannot meet the power requirements.

Wiring Diagram

Notes:

Strictly follow the wiring diagram for wiring. When assembling, first check whether the voltage of each individual battery is within the rated voltage range. If the voltage exceeds (sodium ion 3.8V), the protection board may not be able to be awakened. Please string and connect all batteries before welding the protection board.

Wiring instructions!

The wiring starts from B -, and B-B1, B2... B+are wired in sequence. After confirming that the wiring is correct, measure whether the voltage of board P+P - and battery B+B - is consistent. If not, use a suitable charger to power on. Taking only one string connection method as an example, the same applies to other string protection board connection methods
