About Vision technology
Vision Group is one of the largest manufacturers of rechargeable batteries in the world. We supply both VRLA and lithium batteries. Worldwide sales and engineering centers support customers in portable digital products, UPS, motive, Advantages of Vision LFP batteries
As a substitute for Lead Acid batteries, LiFePO4 rechargeable battery is our new product. Some of the main advantages are as follows: * Safe technology, will not catch fire or explode when being overcharged, because: (1).Fast charge capability that avoids lithium plating at the negative electrode; (2).Dual plate laser-welded aluminum cell construction; (3).Advanced vent technology to safely release gas pressure buildup; (4).Center pin construction designed to allow efficient gas release and avoid internal mechanical deformation * One third the weight of an equivalent lead acid battery; * Over 2000 deep discharge cycles compared to typically around 300 for lead acid; * More usable capacity than that of similar amp hour lead acid batteries; * High discharge rate capability, 10C continuous, 20C pulse discharge; * Unlike lead acid batteries, can be left in a partially discharged state for extended periods without causing * Extremely low self discharge rate, about 1~2% per month; * Does not suffer from "thermal runaway" .It is be accuse there is a special component called PTC insertion (Positive temperature Coefficient).When temperature gets too high, PTC refrigerates by augmenting its resistance, then current steps down until interior temperature gets normal. * Can be used safely in wide ambient temperatures of -20 to 60 deg.C without any degradation in performance. * Can be connected in series for higher voltages or parallel for higher capacity. * Does not contain any toxic heavy metals such as lead, cadmium, nor any corrosive acids or alkalis thus making LiFePO4 batteries the most environmentally friendly battery chemistry available;
V-LFP 12V Series Model

Vision Technology delivers safe lithium phosphate energy
storage solutions in standard lead-acid battery sizes for a wide
variety of applications.
Overview Features
The V-LFP 12V 16~20Ah Energy Storage Systems are a ¾ Built-in automatic protection for over-charge, family of 12V battery modules and accessories. The 12V over-discharge and over-temperature conditions family is designed as a drop-in replacement for similar sized lead-acid batteries offering twice the run-time and nearly half the weight. The 12V series is designed for ¾ Communication of monitored data via Battery lower voltage, lower power and longer run-time applications.They are built with Vision LFP Technology ¾ Thousands of cycles,100% DOD,under normal that offers outstanding intrinsic safety and excellent float and cycle life resulting in low cost of ownership. ¾ Can be charged using most standard lead-acid Specifications

Like Drugs, Talk Therapy Can Change Brain Chemistry By RICHARD A. FRIEDMAN, M.D. After six years of twice-weekly psychotherapy sessions, Eric had plenty of insight. But his anxiety level had barely changed. He was still bedeviled by a ceaseless urge to wash his hands and shameful and repetitive violent thoughts. Out of desperation and against the wishes of his therapist, he visited my offic
