DualUSB module 5V 18650 lithium batteries overcharge / short circuit protection

DualUSB 5V module for 18650 lithium batteries with overload / short circuit protection

Features

·       Designed for DIY power bank: The 18650 battery needs to be discharged and the length is 65mm. The pointed battery cannot be used. If you are using old batteries, with different capacities, the assembled battery is guaranteed for at least 3.5V per voltage. If the voltage is too low, it will not charge. (Note: It also supports lithium battery, mobile phone battery and tablet battery).

·       Supported Connection Methods: Only one lithium battery or multiple lithium batteries can be connected in parallel. The capacity of the connected battery does not exceed 200,000 mA, as long as a battery with a voltage of 3.0-4.2 V can be used. Note: The cable connected to the battery must be short.

·       Protection function: The enhanced lithium battery protection circuit has been built in, prevent overcharging, overcharging short-circuit protection, over-current protection and over-temperature 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 it is reversed, it will burn out !!!!

·       Charging Cable: Supports charging three USB data cables, also for iPhone and Android.

·       Size: 6.5 * 2.5 * 0.1cm; Double output current: 5V 2.4A; Input voltage B + to B-: 3.0 - 4.2V
