Does the balmar voltage sense run on a separate wire all the way to the battery. If not run one. Then custom set your absorption voltage to 13.9v, float 13.35v. Your alternator needs to have a temperature sensor attached to the alternator.You won't over charge with this profile and you will get 99% charged. You don't need a current sensor to fully charge a battery on a alternator as the field current is reduced as the alternator finds it easier hold target voltage. This is called charge acceptance. If your battery monitor is a victon, I would use the inbuilt relay to turn the alternator

Have a look on parts4engines.com whole new raw water pumps are very very reasonable from them.

A new p70 isn't cheap!

It's not that difficult or vastly expensive to spec an engine with big alternators. The picture below is of a recent install of mine with a lithium bank being happily and safety charged at 5.8kw off a 110hp engine with 2x large frame alternators. The Alternator setup including electronics and my time was just over $1 a watt. This was excluding a mount bracket that needed to be made. Totally agree with Islandtime about the comparison with lead carbon, and ill add that lead carbon have pretty bad voltage sag under high load draw in my experience.

Sextant.

It might be helpful to let us know where the boat is?

Active ingredient in wet and forget is benzalkonium chloride, also found in the cheapest disinfectant in pak n save at a similar concentration minus the surfactants.

They rented a small flat in whangarei for a while, and believe they were fixing the boat. But I'm not sure what happened in the end.

This website is pretty sharp for pricing. https://www.parts4engines.com/volvo-penta-d2-40-stainless-steel-exhaust-outlet-kit/

A wool bale needle might be a perfect size for what you are wanting.

I think they use heat set glues for TPU. I would ask Seafarer Inflatables if you can do this, they make TPU inflatables and Auckland based.

Looks really good. What rollers did you use?

Does the headliner come off?

How are you measuring capacity?

Farrell bearings in Hamilton are pretty on to it crowd.

I have a Samsung active tab 3 and it's GPS works perfectly fine without a connection to the internet.

You can put water in ethanol based petrol, and then water and alcohol will then separate from the petrol base and settle. Then all you have to do it drain it away and you have pure petrol.

I would be very surprised if your existing gear can be programmed to suit carbon foam batteries, and then not be programed or made to work with lithium. Carbon Foam batteries do not share the same bulk, absorption, float voltages with any of the other LA batts. What brand Carbon Foam are you looking at?

You could make a signal sensing relay? But I would be inclined to leave them as separate systems and add speakers.

Just a couple of points, without picking at your post. Low balance current on BMS's in the 10 - 40ma range is perfectly sufficient for balancing small to medium lithium batteries. It's just not working how most people assume, as the majority of people are assuming you are removing current from each cell, while the other cells are receiving charge current. In fact what is happening, it the balancing is resistive [yes you do get a current measurement] and works from a voltage drop standpoint. The cells being balanced have a slightly lower voltage, therefore less charge acceptance, with th

Unload...should have read...A load. Autocorret moment.

You are not switching unload, so it will be fine.

I have a Samsung Galaxy Tab Active running OpenCPN. Its waterproof, can be charged when wet, as it has Pogo pins on the side (docks are avalible), screen isn't the best in direct sunlight...But I just move it, DIMs down fine at night, Its tested to MIL-STD 810G US military standard for ruggedness, I use signal K sever [can run on almost any device]for AIS Sonar Data and can run radar this way, Has a S Pen that works when device is wet....but to be fair it works pretty well when wet with your finger anyway. Comes in a 8inch [i have this one] and 10inch sizes. https://www.samsung.com

Once offshore you can register your boat back to New Zealand?
