Anyone have direct experience...

Re: Mother nature vs Schengen: The Transat circle

This website (https://www.etiasvisa.com/etias-news/eu-bilateral-visa-waiver-agreements) explains how a stay in Schengen-land can be extended beyond 90 days in a single Schengen country if that...

Re: Installing an external regulator on a Volvo D2-55

Echoing others, I have been extremely pleased with the addition of a VRC-200 to the Mitsubishi 115 A alternator on my D2-75F. The alternator is feeding 600 Ah of LiFePO4 batteries.

The internal...

Re: Trudesign fittings

Regarding straight threads, there is also the issue of BSP vs NPS. My European-built boat has Trudesign thru-hulls that are BSP so replacing any valves means tracking down BSP valves here in the land...

Re: Wiring batteries in parallel

The Victron batteries require the use of a single Victron BMS and, of course, that's what I'll be using (I've already acquired it). And I'll be going with "C" as that's what Victron recommends. Those...

Re: Wiring batteries in parallel

The Smartgauge article assumes 35 mm^2 wire (2 AWG) for the connections which is definitely on the light side for 100 A draw.

Even such small wire gives only 0.00012 Ohms per 20 cm link. The...

Re: Wiring batteries in parallel

That's a perfectly good configuration for lead acid batteries but for LFP the recommendation is to fuse each individual battery hence the configuration shown in the Victron schematic.

Re: Wiring batteries in parallel

This diagram shows Victron's recommended practice. I'm simply saying that instead of each positive wire being the same length and each negative wire being the same length, what matters is that the...

Re: 31.2Kw Victron LiFePO4 Split System Install

Thanks. That's great to hear.

I'd been told that cell voltages did not get sent to the BMS because the on-off decisions for charging/discharging were made by the internal BMS within the battery,...

Re: 31.2Kw Victron LiFePO4 Split System Install

It is my understanding that the Ve.Bus BMS doesn't get anything beyond on-off type information from the batteries. In other words, the BMS can tell other devices (inverter-chargers, solar...

Re: Possible to convert turbo D2-75 to non-turbo D2-55?

I have a D2-75F which was an upgrade from the D2-55 when I ordered my boat. A couple of years ago it was found that the D2-55 does not meet US emissions standards (yes, we still have some standards)...

Re: Any Ultra Review Updates?

Can't compare against the Spade and Excel, but we're in our fifth season with an Ultra - yet to have to re-set the anchor. A quick blast with the wash down hose and the mud, even that tenacious Maine...

Re: Maretron 2k device network (to) iPad Display

My advice is that you add a Yacht Devices YDWG-02 (if you don't already have WiFi on board) or a YDEN-02 (if you do) to your N2k network. Then, there are several apps you can add to your iPad, of...

Re: Boat internet system recommendations

Two reasons:

First, so I can turn off the BR1 when far from cellular coverage to save power. I find the BR1, perhaps in common with other cellular devices, seems to be power hungry when seeking a...

Would you mind posting a link to the specs of the packets sent by the REC (0x351, 0x355, 0x356, 0x35A, 0x35B, 0x35E, 0x370)? I believe these follow so-called Sunny Island format, but I've not found a...
