The new tabless battery generation.
The new tabless battery generation. The new 18 volt LiHDX battery packs elevate power to the ultimate level. Revolutionary tabless technology makes it possible.
The internal structure of the tabless cells has been adjusted in the 18 volt LiHDX battery packs, so that the anode and cathode are completely connected with plus and minus poles. The “tabs” are eliminated as bottlenecks, and the internal resistance of the cells is significantly reduced.
This design
releases ultimate power
