Hello,

Thank you jonophilpott. PM sent

We have had a few companies reply to emails and Flowfit do an all in one unit (pump, motor and reservoir) which seems to fit our requirements. we may also be able to remove the standard motor and replace it with the Ampflow 48v fan cooled for some extra pressure and weight saving.

In terms of the batteries, We estimate that the drive system is about 2kw, and the weapon motors may be 7kw
we are planning to run two of these in series

This will give us 44.4v to run the weapon system.
The drive system will run at 36v max, so we will have to step down somehow to go to the ampflow dual speed controllers which come with a 5v output for the rc unit.
Will we have to run 2 separate circuits for the 48v and for the 36v systems? (2 battery set ups) and if so, can the removable link essentially be 2 links stick together so that when a single piece is removed it will break both circuits?
