  1. I thought approx 60A was a bit low, but voltage sag would be minimal so is this possible? 1000/13=80A
  2. Pretty mundane in terms of events but something I’d been putting off trying for years because I’ve never needed to. And, conveniently “forgot about it”. I Switched start bank off and emergency on and yanmar started easily. VERY! Quick return to normal and a check of each bms revealed 27A & 28A respectively max discharge during start. BMS’s are 200A max each for 5s so seems ok. I forgot to clamp the starter lead for the inrush current but bms’s didn’t complain so all must be good. So I guess this is a green light for installing windlass & hooking to house bank. Any fried mo

    Thanks, I think I’ll stick to regular buoys.

    Fergie buoys

    Never used one but I am upgrading a mooring and don’t know whether to keep or ditch.
  5. It would be interesting to know the details,whether it was actually the lithiums that started it, brand of lithium, BMS , configuration for charging, safeguards (or not) in those incidents. AGMs of similar capacity cost more than my Lithium. That said, you have got to have X amount of geek in you to be comfortable with the change-over, and could be dependent on what capacity you can currently charge at and whether you have already tweaked it with configurable external regulated alternator . I already had the perfect setup for DIY LiFePO4 and BMS of my choice. Horses for cou
  6. Nah, won't happen to me. 😇 I: 1. Buy ones that don't do that. 2. My decent chargers have inherently better safe guards and I'm glass half full type. 3. I always position charger away from combustibles and easily ejectable to safe open space for exinguishing. 4. I'm ALWAYS present. 5. I NEVER leave them on the charger indefinitely. 6. I have never used "X" batteries rotating, back to back, with multiple chargers, even when they have got hot. Yeah, RIGHT...
  7. I did a bit of hand wringing before I chose LiFePO4. (Actually ordered firefly carbon & cancelled as there was a wait) All that time I've had cordless drills, mini grinders, a laptop and multi phones living onboard with little much of a second thought. A little strange how we perceive risk. I've used an abused these other chemistries for years, (on land) hence no qualms at all.
  8. My diy. (3yrs old) From what I have experienced insurance companies main criteria is that the installation follows manufacturers recommendation and/or is a proprietary system by one of the big manufacturers with a long-standing history, and /or is by the a commercial installer that can prove they have knowledge and history required to combine a multi brand component system. My insurance co had no clue wrt an NZ/Au standard, or ABYC E13 (recommended) for that matter but was adamant that it would only cover me if I could prove I knew what I was doing which was impossible because the
  9. "due to its environmental friendliness and efficacy against parasites." Like antibiotics in chook feed? Or hydrolyzed chook feathers to create high protein salmon food? Baltic sea fish meal with higher than acceptable heavy metals and industrial waste content. What could go wrong?
  10. Ivermectin? Is that what is in sheep drench? It is suppose to fix everything. According to some anyways. Like spike proteins, cancer, cytokinetic storms. Bleach! Trump uses that and his ass is never clean. I want to try west with 33/33/33 Cu powder, Cu2O & PTFE powder + 15-20% solvent, on a test panel. Like an easier to clean and fresh batch of cuprous oxide on each light abraid. Cu for longevity. Too bad when you want to recoat. Mind comes up with odd ideas whilst on the end of RO.

  11. I could use that to isolate my electronics from potentially high LiFe spikes, right? I am on Hobsonville hardstand as soon as there's a decent dry weather window. But can pick up from anywhere in Auckland I see BK regularly.😍 Cheerrs.
  12. Cheers. Garhaeuer is out as 4x price as much as I like their tractorish design. I have bought their clutches before. hard on lines but don't let go. All metal.
  13. Anybody traded with them lately? I'm looking at 2x Lewmar footblock jammers for gennaker sheet. Way cheaper than anything here if i buy at current US$ freefall. Conversely. Rutgersen from Sailutions foot block any good? I will have secondary tie off. Although, Lewmar has better FB on operation. I don't want to remount my secondaries.
  14. "The trailerable AF-33 and Smart Solutions, the only completely metal-free paint in the test, also repelled barnacles. Both, however, had moderate coats of algae that would require cleaning to remove.

I think Micron CSC is the only one available here. I bit the bullet and went back to International Ultra
  15. A decent feed today isn’t what it was even 10 or 15 yrs ago. Because you have fishing skills to can still catch them but the gross breeders are, ahh, rare. We have got used to having to work for a plateful. And baking the whole fish instead of filleting. Went to port Jackson recently, had to dive and chum with kina to get a response. Ended up with dinner, but I should have just shot a couple or Parore while I was collecting kina. Would have been a lot easier. I don’t spear much any more, and definitely not species that are slow breeders like red moki. ( Who mate for life and practically swim
  16. Yip, good idea, I’ll try one handle and see if it works. Devil of a job getting old glue off so don’t want to waste effort to do over. Can’t see getting 5200 off being easy. Last time I added the cross linker demodur but I believe you can just use 999 neat. Demodur is like liquid gold at $80 for a little vile that’s basically useless after you break seal on first use.
  17. Any body had any luck with 3M 5200? I have some over and don't want to waste it. Will still clean old glue off with MEK/acetone and sand. My 999 has gone off and don't need half a litre.
  18. yep, scollies off Mckenzie bay, crays around Rangi in '79. Not hard to get a feed off noisies. Should include GB an all offshore islands from astrolabe to NC. Let the larval stream do its thing. Five yr minimum. Successive govts couldn't have fckd it up any worse, curious to know if private enterprize could do any better. Not that the resource should belong to PE.
  19. I get your point but; You do *need* a bms for LFP if you want any credibility with insurance companies or over anxious berth mates. Or, you want to try and prolong the life of your LFP by a few cycles .Also not having one could suggest legal grounds for lack of safety provisions on *your* installation in the event of injuries. Strike one-diy, strike two -no bms. Or visa versa. My needs are piece of mind in terms of reasonable eventualities. Besides, data is cool.😆 Good bms’s are cheap ! Also I’m getting old and forgetful.
  20. I've heard it suggested that you don't need a BMS for LTO's just an active balancer, as you're not likely to get in the individual cell HV cutoff zone. 2.85x6= 17.1V, so charging at 14.4V would need a serious cell fault.( realising that back out of the knee, rested, is probably in the 2.6V (15.6V) area) Now I am out of the marina I may still pursue the LTO, but will have a bms with active balancing. I can see why your windlass was loving it, 14.4V with very little sag! Makes one wonder the limit V the SM/windlass windings are designed for.
  21. With all the effort to get to start line, having to swap out your LFP would be a mile too far! When are they going to wake up on LFP? 6 cells or five LTO ? " although the LFP was actually just fine", So you did try starting your motor off your house bank? What BMS do you have? (I think you mentioned way back, but cant remember.) I'm all set up to switch to house LFP for emergency start of motor with the three switch setup but never had the need. Unleashing the LTO (6 cells) on your boat glowplug circuitry as you said may result in dead glow plugs at very least. My 3GM
  22. So, you installed LTO? I delayed as start lead is still working. And insurance co scratched their head harder than on LFP.
  23. And you can patch and polish?
  24. Ability to bend rules is directly proportional to how much clout/money one has. Why would we think NZ was any different? Wishful thinking?
