Inspired by your waterproof marine equipment may be you could think about such general product.

Wirelessly charged backup battery pack for outdoors/camping, boat trips, construction sites

- Incorporating both TX and RX functions. Easiest implementation would be that one side is RX and other is TX.

- Hermetically sealed without any connectors or cables.

- It's internal battery can be charged by placing it over a Qi compatible wireless power transmitter.

- Including a LCD indicator with battery voltage/capacity.

Two years ago I bought underwater scooter for diving and swimming fun in the lake.

I it running on 24V 4 AHh lead battery, has a geared motor and two speeds.

Enclosure is hermetic when in water. It is not allowed to be charged hermetically as gas may come out from lead battery during charging and the thing may explode.There is a rubber sealed screw that has to be unscrewed.

I don't know how it is in case with LiPo batteries.

I am thinking on converting my underwater scooter for 5s cell 5Ah LiPos because lead battery has died. Wireless power transmission unfortunately would not be powerful enough to charge in reasonable time.

Hi Eduardo

This sounds interesting. Looking forward following your progress.

From my side I can say, that your English is very good. So don´t worry about that.

This a really good idea, as a former diver I understand the issue relating to electronics underwater. Good luck with the challenge
