SPECIFICATIONS

Brand Name: NONE

Choice: yes

Item Type: DIY Box & Shell

Origin: Mainland China

Product Features:

1. The product is lead-free, allowing users to freely disassemble and replace the battery

2. Equipped with DC constant voltage UPS functionality, enabling automatic charge and discharge management without manual intervention

3. It features multiple output functions, covering three common voltages (5V, 9V, and 12V) for devices such as optical modems, routers, and surveillance cameras

4. Through strict quality control, ensure long-term stable operation and extend service life

5. The product features stable performance with a peak output power of up to 60W

Product Parameters:

Maximum battery capacity: 6 * 3.7V * 3400mAh = 74Wh (Battery not included, user to provide)

Rated output power: 12V5A=60W; actual output power comes from the battery's own output power

Output voltage: Independent outputs of 12V 3-5A; 9V 1A; USB 5V 2-3A; UPS function activation requires meeting input power conditions

The product lacks voltage stabilization, with the battery connected in series for direct output, causing the voltage to fluctuate with battery charge levels

Suitable for high-power appliances that do not require voltage stabilization, such as electric motors, LED lights, audio systems, solenoid valves, and printers

Applicable battery: 3.7V cylindrical flat-head 18650 battery (recommended for power applications)

Charger Type: Internal current-limiting circuit, compatible with 12-13V adapters. When used as a UPS, higher input power ensures greater stability

Charging power: The input adapter power shall meet the requirement of being greater than or equal to the total load power plus the battery charging power of 6W

Overcharge Protection: 4.25V * 3

Low-voltage protection: 2.75V * 3

Overcurrent detection voltage: 0.1V ± 0.025V

Temperature range: -20 to 60°C

DC interface standard: DC5.5*2.1mm (positive inside, negative outside)

Notes:

1. The spring contacts the negative terminal, and the copper plate contacts the positive terminal. Do not reverse the installation; incorrect installation will cause burning!!!

2. Utilize high-quality batteries and enforce strict pairing requirements, ensuring that each individual cell in the battery pack has as consistent parameters as possible

3. This product can only use flat-head 18650 batteries. Sharp-head batteries with a length exceeding 2mm are not permitted for use
