48v battery bank of 4s 12v AGM. When “full” according to the charger the voltage is around 52.8, I have a battery capacity monitor that wants to be set to 48v, lead acid, and it wants a voltage

I assume your 48 Volt pack is made up of four 12volt batteries in series. Do you charge them in series i.e at 48 volts+ or do you charge each 12 volt battery separately? If separately do you

FWIW, I have a separate 48 volt propulsion bank & 12 volt house bank. I charge both banks with 260 watts of 24 volt panels wired in series using a midnight kid solar controller. I wired the

I like the mppt charger because they usually have adjustable voltage and amperage tsp can use for many battery types

DC-DC converters are simple: they produce the lower voltage from the higher voltage, and supply current up to their max rated power throughput. On my boat, I have no lower voltage batteries, so if

I just took a look in my engine room and I do think I could possibly mount the motor directly onto the transmission.? Orest, would you be willing to post a photo of your arrangement?? I'd be most

I was intending not to have to install any kind of clutch.? My thinking is that I could allow the diesel to drive the motor as a generator until the batteries were charged and then the motor would

That's an interesting idea Darryl but I don't think I'd be able to fit something like that in my case.

I found a 72v to 24v converter on an ev automotive sight. It charges at 50 amps. I don't know much more than that about it. Is there anything else I should be aware of? [email protected]> wrote:

Just use the battery pack as the solar arrayJust like dc to dc

Well as far as another mppt controller, I was thinking they take higher voltage in and put out the voltage you need for the battery bank. I was going to feed it with the 72v bank so I would only need

Mppt?charger maybe cheaper?

I would go with the DC-DC converter as the simpler option, assuming you can buy one that steps down that far: 72V to 12V or 24V. That's how mine is setup, though my motor only needs 48V. I'm guessing

I have gone the double belt route after the one belt experiment kept slipping and burned out bearings from the tension. Now I use a goodyear synchronous (like in a supercharger) and have not

I purchased a sailboat that wad in the middle of a refit. The previous owner already removed the diesel and had purchased a the components to go electric. The motor is 72v and I've found that the

Hi Matthew, I don't know if you have the space for this sort of arrangement, but back in the 1980s Briggs&Stratton had an interesting set-up in a hybrid electric car prototype. Here's an image from

Wonder if you could install a tensioner pulley of some sort if you wanted to disengage the electric. But don't see why you would want to the seems the electric would work well as an alternator to

You’d have to be able to swap between the diesel and the electric motor on the drive shaft, otherwise the electric motor would act as a giant alternator when running the diesel and that would

Hi Matthew, Would you plan to somehow disengage the belt to the pulleys when using your diesel motor?

Hi folks, I'm new to the group and enjoying reading old posts and learning a lot about electrifying boats. This may have been covered in older posts so please excuse me if I'm bringing up something
