Sourcing a Battery Pack for ROV deployments
Sourcing a Battery Pack for ROV deployments
(OP)
Hello All,
I have an instrument which needs to be deployed, along with an independent power pack to act as a UPS during the deployment. Does anyone have any recommendations on sourcing a deployable battery pack, including a pressure vessel. The battery pack's pressure vessel must be rated for 2000m depth. The pack has to be able to supply 12+ Ah with peak draws at 5-6A and steady current in the ballpark of 3-4A. Any thoughts on the topic are appreciated.
Regards

I know silver zinc batteries are used at that depth, for example. It would appear to be attractive to use a vanadium pentoxide redox battery system, since all the working fluids are aqueous solutions it would not need a pressure vessel.

RE: Sourcing a Battery Pack for ROV deployments
Thanks for getting back. Here are the requirements :
24V DC
Discharge rates must be able to spike over 6A
Discharge rates are generally 3A
Requires 20 - 25 Ah
When you say that a Vanadium Pentoxided redox system would not need a pressure vessel, are they built to flood with ambient water, or are they filled to equalize pressure without any internal voids ?

A redux batter pumps an aqueous solution into a reaction chamber and then stores the waste in another tank, so external pressure equa;izes quite nicely.

RE: Sourcing a Battery Pack for ROV deployments
I'll check out your links, thanks. Any thoughts on Redux battery sources ? I'd probably better look at a catalogue

RE: Sourcing a Battery Pack for ROV deployments
I was really not being specific about the battery sizes, just ball parking the roughest possible boundaries of my system. It's early in the design, so I don't want to get bogged down in decisions which may limit my options.

I've personally used the DSPL packs with good results.
