ECS Winston mounting kit. now also available with openings for cable ducts!

New cell connectors for EVE, Lishen and Calb cells. Flexible and high currents (crosssection 60 mm2 and 120 mm²) 

Development project started:
Extremely powerful lithium battery with an integrated new type of BMS.

In the last few months we have been hardworking and have added many new products to our range
  • Automotive fuses with a very high breaking capacity in the event of a short circuit (10 - 50 kA). These fuses have been specially developed for use with lithium batteries.
  • Product range at NH fuses expanded. There are various new types and a new addition to the range: fuse switch disconnectors. So fuse holder with integrated main switch function.
  • New in the program, power rails in various designs.
  • Powerful cell heaters and isolation plates for LFP cells.
  • Flexible cell connectors for LFP cells from CATL / LISHEN / EVE
  • Finally the time has come! Our high-precision battery monitor, named greenMeter, is now available in our shop. After more than two years of development, we are proud to have achieved a measurement error of less than 0.04% FS. With this you get the most accurate battery monitor from us. We offer this sensor in three different current measuring ranges, so scaling to your area of application is guaranteed.
  • Our greenViewM Android app has been heavily revised and improved for you.
  • Our new ECS Kommtool software now also supports multiple battery systems. For example, it is possible to display both the battery system for the main power supply and the battery systems for the drive motors (e.g. for boats) in one clear program.
