I just removed a frozen Borg Warner Diesel engine from my 55’ sailboat, and am in the process of repowering it with electric. I’ve spent a great deal of time on this site and others trying to

I have a 12m cat with 2 Thunderstruck set ups with their standard Chain coupling. Works perfectly with minimal vibration.

I’d suggest a dc/dc charger - http://www.battery-management-voltage-converter.com/m.step_down_dc-dc_battery_chargers.html also a 72vdc generator with auto start/stop. Polar Power May be able to make

I would definitely worry about, and fortify your cutlass bearing but I can say for sure that the electric motor and the bearing on the Velvet drive transmissions are NO PROBLEM. This was a big concern

I have hand-me-down batteries so it’s hard to set a meter correctly. I’m not sure what condition they were in when I got them. Never got around to doing proper capacity testing. For semi accurate

Here is a reference that I would look at: *https://modernsurvivalblog.com/alternative-energy/battery-state-of-charge-chart/*

I subscribe to an electric boat group. This is a recent post I thought you might like reading.

I have not used my e-propulsion T'struck 10kw system for trips, only as an auxiliary for marina exit/return. Sometimes against a 2-3 knot current. Just to set comparison: Are you using the

Solar Boost Controller Specifications： Color：Black Material：Metal Size：11 * 10.3 * 4.2cm / 4.33 * 4.05 * 1.65in Weight：360g / 12.69oz Input Voltage：15-45V Output Voltage：48V/62V/78V

Bob is right. Even without electric propulsion, voltage isn't a good measure of state of charge. With the huge power draw of propulsion, the voltage will drop below values that would be alarm-worthy

Why bother connecting to the solar charger from your generator? Just connect a proper charger right to the battery bank. If the generator come on due to low voltage obviously the solar charger is not

Thanks for this explanation. Can you tell me the model of Boost controller Rgds Peter

I've tried several of the ideas listed on this subject... what has worked best for me: I presently have 2 x 100w solar panels connected in series to provide 24v plus. I use a "boost" mppt solar

They make 12v batt chargers that take 48v input. I have one but haven't installed yet as I still have a separate panel and charge controller for 12v. I want that real estate back though so I can use
