Our new power tool battery is a huge improvement on previous scooter batteries. It's compatible with all Piranha scooters and can be used together with older batteries in P1 and P3 configurations.

The battery is a housing into which four power tool batteries (that you can source online or at your local hardware store) are dropped in to create a larger battery. This offers some huge advantages to you, the diver:

  • Battery packs are available almost anywhere in the world.
  • It can travel with you on regular airline flights*
  • Same size, weight, capacity, and power as the original Piranha battery
  • No hazmat shipping when purchasing
  • Easy to replace packs as they age and deteriorate.

*Each pack is less than 100wh and is compatible with current airline regulations.

Power Tool Battery Module (battery packs not included) with Universal Strap and extra trim weights.

To use, the purchaser will need to source their own power tool batteries as described below and the relevant chargers.

Important Facts

Don't leave your battery connected to your scooter for long durations. Even though there is protection, it may over-discharge the battery. Always connect your battery just before a dive and disconnect it soon after.

For air travel, always check current regulations. Travel typically requires you to carry the individual power tool modules in your hand luggage.

For US customers, you have the option of purchasing the PTB Module Kit with or without packs and a charger. For international customers, you can only purchase it without packs and chargers.

The best option for all customers is to purchase it without packs and chargers, and then source your own locally.

Included in the box will be:

  • PTB Module Body Tube
  • Salt and freshwater trim weights
  • Universal strap to be used in P2 or P3 configurations.

If you do purchase it with packs and chargers, we will drop ship 4 packs and a dual charger to you from an online supplier.
