Welcome to VisBis
VisBis is the subsidiary of Luminatek company in the business of helping other companies develop
products. Our engineers have many years of experience in a wide variety
of fields. We now concentrate on helping other companies
engineer their power needs--batteries, power supplies, inverters and D.C. to D.C.
converters.
We not only engineer products, but
we also manufacture products both in Utah and in China. This helps our
customers and keeps us in lasting, long term relationships with both our
customers and our factories. We are truing to be cost effective and sell our products to smallest mark up. Very often we modify our existing products to your needs. For our buyers from North America, please go to Powerstream website.

There are many other battery chemistry, each with their own advantages and disadvantages. Also batteries classified under their shapes. In the last few years a few geometrical shapes became very popular.
This calculator helps to compute current limiting capacitor for low frequency (below 60Hz) AC sources of voltage.
In the new era of LED (Light Emitting Diodes), most of consumers start
forgetting CFL (Compact Fluorescent Lamp) & CCFL (Cold Cathode
Fluorescent Lamp). ...apparently fluorescent tubes received second life.
This calculator determines the total required battery capacity (C) in
ampere-hours (Ah) for two sequential discharge events. It accounts for
the load currents (I1, I2), discharge times (t1, t2), discharge rates
(Rc1, Rc2), and includes corrections for non-linear effects in internal
resistance at low states of charge (SoC).
