Battery monitoring

Challenge:

Lithium polymer batteries (LiPo batteries) are popular in model making because of their good weight-to-power ratio. They offer high power density, but carry risks such as puffing (swelling of the battery) and, in the worst case, thermal runaway.

This can lead to fires and significant damage to buildings and facilities, especially when charging is left unattended. Although such incidents are rare, the potential consequences are serious.

Previous safety solutions are usually integrated into batteries or devices. However, a universal, mobile solution specifically designed to monitor puffing has been lacking—until now.

The innovative security solution

Our new safety device monitors both the swelling and the temperature of the battery – simple, effective, and independent of the location of use.

An adjustable strap is placed around the battery to fit its size.

Both switches keep the circuit closed under normal conditions.

As soon as the battery inflates or exceeds the defined temperature limit, the circuit opens automatically – the connection to the charger or consumer is immediately disconnected.

The device is universally applicable, compact, and can be used on the go at any time.

For every safety-conscious model builder, this gadget offers a simple and inexpensive way to charge batteries and prevent potential fire or property damage.
