Beta engines are Kubotas which have parts and service world wide. Beta just adds all the stuff needed to run them with water cooling and other nice to have things like an oil change pump.

I too, love my Beta.

Beta Marine Diesels are made in the UK...I would imagine you could get it serviced in the UK. Last time I checked, the UK is outside of the US.

Love my Beta!

Beta all the way

We also repowered our 36 sail boat from a Perkins 4-108 to a 38 hp Beta. So far, OK only 15 hours on it but it is still kicking!
See post “Any pros cons on the Beta Marine engines please?”

Capt Len Regardless of who you are dealing with, a Kubota has got to be the best bang for the buck

tommays Well

The DC to AC deal would happen in the control and is how its done in the most modern forktrucks

A big issue on a motor that size is it will need a powered cooling fan which will eat some amps

Even a AC VFD drive goes AC to DC back to AC to perform its tricks

thus my comment about a spectacular failure of a component...

and without proper fusing or current limiting hardware, the "motor" may spin once or twice and then the batteries may flash/incinerate/smolder...that current has to go somewhere.

And if there is a weak/marginal cell or poor manufacture...well about the same result.

the exide paper is just their spin sheet....nothing new there.

the bigger question is how are you going to convert all this DC to 3phase 200 VAC that the motor you mention requires...or did I miss something there..?

mitiempo Exactly.

As you will have 20 batteries take your lower voltage of 200 and divide by 20. That equals 10 volts and you will never get there running a motor. 50% SOC for your massive bank is about 240 - if you go much lower the batteries will have a very short life.
