We bought bluerov2 and we want to improve the design for capability of diving more than 300 meters and in this direction we bought also aluminium tube for electronics parts; however there is no aluminium tube for battery enclosure, because of this situation we are going to produce our own aluminium battery enclosure.
It is written that aluminium tube guaranteed to dive 400 meters, so how about the penetrators, front glass, and connectors is it enough to dive these meters?
We could not make sure about the selection of battery, we are considering the buy one of these battery at the below.
Which one could be more efficient for us and how many baterry should we buy ?
Which specifications should I consider to buy for these baterries?
Is this baterry charger convenient for these baterries?
Thank you for answers.
