Note:

Any close above 3.65 v input a string of battery, then equilibrium, balanced with light, which full of be clear at a glance all the way!

Any shut down a string of battery is lower than 2.50 v output. Completely protect your expensive of lithium iron batteries!

Balanced current increased to 80 from 80 ma ma, electrify equilibrium time is shorter. better

High precision integrated chip control, high stability;

MOS tube drive: able to discharge, over current situation rapidly shut off, over current situation is solved by using the MOS tube, such as can't shut off quickly, during internal resistance increases, lead to rising temperatures, even burned MOS tube.
