I am at the beginning of a conversion for a 32’ ketch, and I have the 10kw thunderstruck kit, charger, reduction, and battery bank all working on my bench under artificial load. She will be at a

Jerry,Unfortunately, the wiring on the batteries is small.? Probably only good for 30A.? I currently have a 30Amp breaker between the battery and the motor to prevent overheating the wires coming

John, Please cranky uppy to 4k watts and let us know results. I got a 2.3 kw chinese motor and building 12' catamaran dinghy. I think I can get by with the one motor but may need two. Thinking bike

On Monday, 6/22/20, I conducted my first on the water Lake trial with my electric conversion, "Mischief".Mischief is a home built plywood runabout, currently powered with a Torqeedo 4R outboard.?

Not sure where you’ll find a split cogged pulley. Not sure what you mean by “pack?” The Thunderstruck motor mount will not work for you, as is. But you may be able to remove the stub shaft and

Hi Reuben, Thank you! That helps a lot. I was trying to get away from machining a keyway by bolting onto the coupling - the keyway would be much more costly and time consuming. I totally agree with

There’s no free lunch. If the motor is generating 5kW then you’ll be using 5kW if diesel plus at Keats 10% for losses. that said, it’s more efficient than adding a stand alone generator making

A 1” clogged belt is OK for 10 kW. That’s what I have. Perhaps you’ll need the shaft pulley aft of the coupling - you’ll need to pull the shafts and have them machined for the pulley key way.

We are planning the parallel hybrid on our powercat. At the moment, the thought is to attach a plate to the existing shaft-gearbox coupler (which I assume is there for some flexibility, like a more

Thanks Steve. I have watched the YT of Bruce Wilson on his Lagoon 410 too! It is great to see people out there doing it.

Well, there’s no actual system yet except in my head. I would certainly like the ability for the motor to act as a generator when running under diesel. i understand though that it depends on the

I just purchased a $24 contactor from Amazon that could work for you: **** WINJUN 4Pin Auto Starter Relay 12V DC 500 Amp Vehicle SPST Contactor I’ll use it on my charge bus with max current

One other question I had - and hope one of the experts can answer this: I don't see a max voltage rating on the contacts for any of the contactors.? Only the voltage of the coil, and the amperage

Don't get me wrong, if someone lacks sufficient knowledge to safely and effectively engineer and build their own system, they should absolutely go with a turn-key offering and pay someone else the big

I bought a NOCO Genius GX4820 that has settings for both AGM as well as LIFPO batteries.? Look at Amazon

I have one left over from my upgrade to lifepo4. I bought it from thunderstruck

I don’t work for a company that has anything to do with electric conversion etc. but I would like to say here that having a resource that has the knowledge to make these systems work reliably and

Any recommendations on a battery charger for 48v 200ah AGM?

Here's another more affordable option than thunderstrucks

If you are using a 48v nominal bank with a max amp draw of 50a, but the golf cart contactor should work just fine as the motor that the golf cart relay was designed to potentially energize has a
