Re: Ultracapacitors parallel to houe battery.

If you read my previous post, you'll see that I can crank my 175 HP Yanmars with no more than 200 amps. Hence, I think it highly unlikely you'll need that much to crank your little engine.

Re: Variable Speed Fresh Water Pump

Just about four years now, on our Whale Watermaster automatic (variable speed) pump, and it's been a totally smooth experience (we're full-time live-aboards). Quiet running, and no hammering.

Re: Tablet for Navionics

Wholybee is absolutely correct - there is no version of Navionics that runs on Windows. You need either Android or iOS.

I agree it is much easier to use the tablet in a waterproof bag than to find...

Re: The reason lighter cats are safer?

A bit pedantic, perhaps, but I'd like to very strongly proclaim that a sensibly skippered cat will not have any great risks at all, whether lighter or heavier displacement. Conversely, a cat (or...

Re: Quiet water pressure pump

Re: TV or projector?

I'm also a movie lover, and to me, size is important - much more so than resolution. On our cat we have both. A 65" OLED screen on a bulkhead in the starboard forward cabin. It's the one being used...

Re: Spectra Watermaker Vane Pump Feedback

A VFD changes both voltage and frequency, keeping a constant volts/Hz ratio up to rated full power (50 or 60 Hz). If the VFD is capable of going above 100%, the voltage is usually kept constant above...

Re: Spectra Watermaker Vane Pump Feedback

Are you sure the Bartscher regulator is a VFD (Variable Frequency Drive)? Many inexpensive motor controllers are not actually inverters, which regulate both output voltage and output frequency.

Re: Digital Storage and Play DVD's

Some smart TVs will have a media player capable of doing this, others will not. Check the manual for your TV first.

Much more flexible, and with far snazzier user interface, is using Kodi, as...

Re: Lifepo4 Charging

Re: Lifepo4 Charging

Repeated testing, both in controlled laboratory settings and real-life scenarios, has shown this approach to damage the cells.

The fully charged resting voltage of a LiFePO4 cell is around 3.35V,...

Re: Lifepo4 Charging

Recharge rate (current) is a function of rate accepted by the battery bank and rate available from charge sources. Since LiFePO4 batteries are both documented and tested to readily accept 3C, it...

Re: Lifepo4 Charging

Paul's advice is generally agreed to with respect to LiFePO4. Used to be that manufacturers would indicate 1C as the max sustained, repeated charge rate, but that now appears to be have been reduced...

Re: Deconstructing Spectra's Clark Pump

While I have studied the Clark device fairly deeply, it would be speculation to state what might happen if used in the proposed scenario. However, perhaps a deeper understanding may help you figure...

Re: Deconstructing Spectra's Clark Pump

The Newport 400 uses a 10% Clark pump. In larger systems, such as the Newport 700 and Newport 1000, the 20% pump is used. Hence, the possibility of simply expanding your system from one to three...

Re: WiFi Boosters - what to buy

Re: WiFi Boosters - what to buy

I'm assuming that's directed at me, with respect to the Bullet M2. At first, I thought perhaps you were joking, about 100 Mbps being a limitation, and then I realized you were actually serious.

Re: WiFi Boosters - what to buy

I'm using the Bullet M2, hooked to an L-com HG2415U-PRO antenna, and have had very good success. I can usually stream video when neighbors can barely browse.
