3D model description

This is a battery holder to replace a 4.8v NiMH battery pack for my kid RC car. This is a design specific for the WomToy Waterproof Stunt RC Car that you can find on Amazon.

You can probably use it to replace any 2x2 AA battery pack since the design is very compact.

You also need some metal piece (I use some galvanize steel from a air duct) and a connector that fit your car. For me, it was a sm-2p connector and you can also find it on amazon.

There are two great think about this design:

  • You can use standard AA NiMH battery to power the car. This is a great because the original battery only last 20 min. and have to be charge 6 hour...
  • The original battery is only 700mAh which is not much. Now, I use 4 AA 2800mAh so my kid can play more than a hour before a need to swap the battery.

Ce modèle est un support pour remplacer un pack de batterie 4.8v NiMH pour une voiture téléguidé de mes enfants. C'est un modèle spécifique pour la "WomToy Waterproof Stunt RC Car" que vous pouvez trouver sur Amazon.

Vous pouvez sans doute l'utiliser pour remplacer n'importe quel pack de batterie 2x2 AA puisque le design est très compact.

Vous aurez aussi besoin de quelques pièces de métal (j'ai utilisé de l'acier galvanisé d'un conduit d'aération) ainsi qu'un connecteur qui correspond à votre véhicule téléguidé. Pour moi, c'était un connecteur SM-2P que vous pouvez aussi trouver sur Amazon.

Ce design apporte deux avantages:

  • Vous pouvez utiliser des batteries AA NiMH standard pour alimenter le véhicule. C'est pratique puisque la batterie originale ne dure que 20 minutes et prend 6 heures à charger...
  • La batterie originale n'est que de 700mAh, ce qui est très peu. Maintenant, j'utilise 4 batteries AA 2800mAh, ce qui permet de jouer plus d'une heure avec le véhicule avant de changer les batteries.
