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

Features

• Designed for DIY power bank: The 18650 battery must be low and the length is 65mm.
• The pointed battery cannot be used.ÿIf 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 several 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 protection circuit of the enhanced lithium battery has been integrated, prevent overcharging, protection from overload short circuit, 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 !!!!
• Charging cable: supports charging of three USB data cables, also for iPhone and Android.
• Size: 6 , 5 * 2.5 * 0.1cm
• Double output current: 5V 2.4A;
• Input voltage from B + to B-: 3.0 - 4.2 V.
