RC3563 is an extended tester of internal resistance. It can be used do test various types of batteries, accumulators and capacitors. These can be, among others,in. : traditional lead-acid batteries; modern lithium iron phosphate batteries (LiFePO4); Lithium-ion (Li-Ion) cells; Lithium-polymer cells (Li-Po); nickel-metal-hydride (Ni-MH) and nickel-cadmium (Ni-Cd) batteries; electrolytic and ceramic capacitors; This will allow you to quickly and accurately assess their condition, as well as diagnose related problems. Thanks to this, the tester of internal resistance RC3563 is an instrument that will be an invaluable help for professionals dealing with such activities as: construction and servicing of do power tool battery packs sale of car and motorcycle batteries; serwis of passenger cars and construction and agricultural machinery; serwis of electric and hybrid cars; sales and serwis of scooters and electric bicycles; The purchase of the RC3563 battery internal resistance tester will also be a great investment for hobbyists who want to build their own “Off-Grid” or “Powerwall” solutions. Thanks to it, it will be possible to quickly assess the consumption status of type 18650 or 21700 batteries from unpackages or recycling of electronic equipment. This will allow you to achieve maximum efficiency of your projects while minimizing their total cost. Thanks to the use of a precise measuring system tester internal resistance RC3563 ensures high accuracy of the obtained results. It is ona about 0,5% for both resistance and voltage. The device also offers an extremely wide measuring range. This is from 1 µΩ do 200 Ω for resistance and 0,1 mV – 100 V for DC voltage measurement, respectively. The Tester of RC3563 internal resistance is easy to use. If necessary, it can be highlighted, which will significantly facilitate its use in difficult lighting conditions. The RC3563 case is made of high-quality plastic, which is why it is durable and scratch-resistant. Inside it was also installed a capacious battery, which will allow you to use the tester in virtually any place. Do its charging is used micro USB port, so that the device can be powered by a classic charger do smartphones. The micro USB port also allows you to connect the internal resistance tester RC3563 do of your computer or laptop. This will enable a thorough analysis, thus providing much better diagnostic capabilities. A set of measuring wires is included.
