Battery protection box and prevention box for E-Bike batteries and other Lithium batteries - Made in Germany!

Lithium batteries are dangerous goods!

Good to know that nothing worse can happen, because the E-Bike battery is safely stored in the battery protection box. If you store your E-Bike in the basement, in the garage or even in your home, you should have the best insurance against battery fire - the ProSave-Energy Preventive Box for E-Bike and Lithium batteries.

The battery protection box variants:


    With dimensions D x W x H:

  • 41 x 24 x 22cm for approx. 3-4 batteries
  • 55 x 24 x 22cm for approx. 4-6 batteries 

Both prevention boxes are available with or without 220V connection inside the box, e.g. to accommodate a charger in the box or a multiple socket for several chargers.

For dealers:

Do you know how your e-bike customers handle the batteries? We receive a daily flood of them in our BMZ service center and the results are alarming! Batteries often have water damage due to improper handling. Scrapes and damage are evidence of violent impacts, which of course can also affect the cells in the core pack. It is bad, if a bicycle dealer takes an e-bike for repair, pushes it into the workshop and the next morning the bicycle store is no longer there - cause: battery fire !

Insurances pay less and less in case of damage - dealers are stuck with the costs - financial ruin is imminent!

Therefore everyone can now protect himself perfectly with the Battery Prevention Box as protection against avoidable fires.

There are also many advantages for end customers:

  • cheaper than any mixing, because in an emergency only battery and box are affected
  • eBikeakku can be stored safely
  • Environment does not take fatal damage (apartment fire, house fire)
  • the battery is safely locked away in apartment buildings
  • a battery fire cannot cause a house fire
  • Turn off your E-Bike, place the battery in the protective box with charger and lock it
  • Lock your battery safely away when you leave your e-bike unattended or even when you leave the parking place

The box can be revised/overhauled after damage caused by a battery fire - you do not need a new box, we offer the appropriate service here.
