DualUSB 5V module for 18650 lithium batteries with overload/short circuit protection
Features
- Designed for DIY power banks: the 18650 battery must be discharged and 65 mm long. Pointed batteries cannot be used. If using old batteries with different capacities, the assembled battery is guaranteed to be at least 3.5V per voltage. If the voltage is too low, it will not charge. (Note: also supports lithium batteries, cell phone batteries, and tablet batteries).
- Supported connection methods: Only one lithium battery or multiple lithium batteries can be connected in parallel. The capacity of the connected battery is not greater than 200,000 mA, as long as a battery with a voltage of 3.0-4.2V can be used. Note: The cable connected to the battery must be short.
- Protection function: Enhanced lithium battery protection circuit has been integrated, preventing overcharging, overcharge short circuit protection, overcurrent protection, and overtemperature protection. Note: The positive pole of the battery is connected to B+, and the negative pole is connected to B-, do not reverse it. If reversed, it will burn out!!!!
- Charging cable: supports charging of three USB data cables, including for iPhone and Android.
- Dimensions: 6.5 x 2.5 x 0.1 cm; Dual output current: 5V 2.4A; Input voltage from B+ to B-: 3.0-4.2V.
