Description

UPS module 12V 24W

===============

DC 12V/15V 24W 1A UPS Power Supply Module Uninterruptible Power Control Board 2S V4.0CN Charging Step Up Protection Module

12V Charging Step Up Booster Module for 18650 Lithium Battery UPS Voltage Converter Protection

A good board holds 2 A, made additional cooling in the form of a radiator, glued on the back side. Battery charge 700 Ma. To the AKB added a passive balancer. 

BE6000 and terminal for Internet pulls. Their consumption 18 VAT is approximately. Sharks of 21700 format capacity turned out to be almost 14000mAh. The throttle is small when it charges very hot, when it charges everything OK. I got the radiators on the wire and on the small and on the big one. temperature with radiator when The tastes are charged and the Internet works large 30 degrees, fine 60 ~. Degrees. the power supply for this business took 12 volts 4 amperes (honest). I watched the consumption through the aimax, there were 12 volts and up to two amperes with a charge of sharks (I don't remember how discharged I was).
I have time to charge my batteries about 3,5 hours before full time. I have not checked how much the Internet will keep before the shark discharge, it will last for three hours for sure. The diode was soldered on three legs but the indication does not work, you have to climb with a multimeter or Felt the small radiator. wrote to the seller to tell me what is needed but the seller does not know what he is selling and sends to read the description of the goods. And so the fee is steep, pulls the voracious Wi-Fi which does not work from China
