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.

Wiring, installation and all about wires
This page will give you some basic knowledge about wires and also provide and few useful calculators for different electrical parameters, dependent on wire size. Please note: WE DO NOT SELL WIRES.
Voltages and plug styles used in different countries.
Please note that some countries have changed their standards, and some have multiple standards. This is not absolute knowledge, but rather for references only. Normally outlet standards heavily regulated by safety authorities in each specific country.
Battery Capacity calculator. Dermines battery capacity (C) in ampere-hours (Ah) for 2 (two) sequential discharge events.
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).
