Mobile, variable voltage source with 18650

Mobile, variable voltage source with 18650

18650 batteries and a step-up converter result in a mobile voltage source.

z. e.g. on Ebay:
DC-DC Adjustable Step-up Power Converter Module Output 5V-35V MAX 3A
Technical data:
- Input voltage: 3.5V-32V
- Output voltage: 5V-35V
- Input current: rated current 2.5A, max 3A (additional heat sink is required)
- Load regulation: 0.5%
- Voltage regulation: 0.5%
- Operating temperature: -40C- + 125C
- Size: 42mm * 22mm * 14mm (L * W * G)
- Note: the Step UP regulator cannot be used to reduce the voltage.

The battery contacts can also be found on Ebay

Deep discharge of the batteries is not possible with parallel connection, as the converter does not work with less than 3.5V.
