Review on πŸ”’ Enhanced Safety with Onyehn Protection Protector Disconnect Discharge by Mark Hart

Revainrating 5 out of 5

Ideal for protecting lead-acid batteries in children's ride-on toys.

It seems that Peg Perego doesn't use any kind of battery protection in their kid's ride-on toys. My guess is to sell more of my very expensive batteries. The lack of protection circuitry will result in frustrated kids draining the battery to a dead end and constantly stepping on the accelerator to kill them some more. Once lead-acid batteries drop below 11 volts, they become irreversibly damaged, and the damage only lasts once. When the circuit is installed, the toy will automatically disconnect from the battery at the set level. Now children can accelerate as much as they want and the battery is saved.

Pros
  • Reset: With the device off, press and hold the two buttons at the same time, then turn on the device. At this point, "888" will appear on the screen, indicating that the factory settings have been restored. Factory set protection value: 12 V, difference value: 2 V. "Differential value" is the value between the battery voltage for disconnecting and the battery voltage for reconnecting.
Cons
  • There are other interesting options.
