Bosch Core18V Battery Pack Video Overview

We had the opportunity to get a close look at the new Bosch Core18V battery pack at World of Concrete in Las Vegas back in January. Bosch moved into the upgraded lithium-ion category in three key ways with the Core18V (it goes by Eneracer in Europe).


First, Bosch made the move from the 18650 lithium-ion cell to 20700. It’s a bigger cell that carries more potential energy. They also changed up the pack’s cooling technology. Now the cells are completely separated and the pack has better heat dissipation characteristics.

Finally, engineers worked with the cell connections. In the old batteries, a simple soldering method was used. In the Bosch Core18V pack, it’s now laser welded with a copper connection. The result is reduced resistance which allows for more efficient energy transfer. In other words, they can get more power and runtime out of it.

Check out the video or our full written preview to get more details!

Not to go off topic too much, but…..

Whats the ‘charger’ looking thing in the background? (visible throughout the video, first appears around 0:12 into the video.) Is Bosch coming out with a dual voltage charger setup?

Thanks for the info on “CORE”, cant wait to get my hands on some and put them in rotation with our crew.
