Why would you chose this product?

Lipo alarm is an economical and very easy to use safety mechanism to protect your batteries. Any Lipo battery that is constantly discharged too far will be damaged beyond repair. In the short term this will only affect performance, in the long term, the battery will need to be replaced. Ideal for younger RC users that need a loud alarm to let them know to stop using the model. Definitely worth having a few in the field box at all times!
