Submerged Time Limit



I know the Open ROV v2.8 has a battery life of 2-3 hours but just wondering if there is a max time that the unit can be submerged for?



Hey Robyn,

I can’t answer your question, but I can share my experience.

I used my OpenROV 2.5 to inspect a well and the tether got stuck. It remained in the well at 4 meters depth for about 20 hours. I had disconnected the power to the topside adapter overnight.

The next day after recovery, there was a very small leak (some corrosion, but no damage) in one of my battery tubes. The battery tube sealing has been upgraded since v2.5 and I suspect the leak was caused during the recovery.



Hi Mike,

Thanks for the reply, I can only assume that as long as the battery has power and no leaks occur the unit can stay submerged.
