    Best battery for electric windlass

    The discharge rate on those LTO's is really impressive. Very interesting.

    Best battery for electric windlass

    Erm... starter batteries are not made to run a high load for 3-4 minutes solid. They are made for the 15-20 second start load. You really want more of a dual purpose starter/deep cycle for this in lead acid land. My windlass spec's in at 1200 watts, at 12v that's 100A, at 14v, more like 85A...

    Best battery for electric windlass

    @mikefitz please expand on that - why do you think that lead acid is the way to go for a windlass battery? You've given no reason. As long as the battery is built to handle the discharge rate I don't think I agree.

    Best battery for electric windlass

    A bit ironically, I decided to put in a 24v alt + WS500 to charge my main pack. So I'm looking at making up 2 or 3 packs: Windlass, Engine Start and something to drive my new electric winches.

    Keel up 12/24/48V new system questions

    That's quite a few voltages to deal with. My system is similar on my 46ft 24v Lifepo4 pack 915Ah 5000/24 Quattro 3x 550w panels with 100/20 mppt controllers for each. DC-DC to AGM 12v pack Cerbo GX OrionBMS JR2 with Canbus to the Cerbo Coming soon: WS500 Regulator (also canbus to the Cerbo) 24v...

    Custom panel builds

    Love that vid, don't chew on your lead solder and you should be fine. :D

    Custom panel builds

    Given the cell outputs, I'm digging this. The marinized cells are $$, but in reality they are just custom made with a frickton of resin on top so people can walk on them.

    Custom panel builds

    hmm ok I found an older how-to vid, seems like just a solder job. not to bad. Vid in question:

    Custom panel builds

    Without too much work I found 100pc of sunpower cells with tabs for $340 on aliexpress. That's really not bad at all. I'm thinking I can use my battery spot welder on these things maybe...

    Custom panel builds

    I'm just starting to dig into the idea of a custom panel build. What do I mean? Well, I've got this: Which I've built using finished nidacore panels. It's the new hard bimini for my sailboat. It rocks in at 8 ft by 12 ft! I've got three 550 watt panels I was planning to stick on here. I'll end...

    I need a standalone BMS that tracks current uptake to the LiPo4 cells

    I actually need to have a convo with them - I've yet to see it show active balancing. I've had tons of other things to deal with that took priority over it tho

    I need a standalone BMS that tracks current uptake to the LiPo4 cells

    I skipped past a bit. I use an orionJr2 BMS on my boat. It uses a hall effect current sensor and talks canbus to my victron system. As a backup, I have outputs from it that feed into some optoisolators to deliver enable signals to charging and discharging systems. This also lets me integrate...

    Cinergi's 28 kWh / 4 kW Solar / 10 kW inverter RV build

    Hmm, too bad they aren't nickel plated. (don't appear to be in the photos)

    Next round coming soon...

    The windlass is built for 12v. It's a $300 motor swap and another new contactor to make it use 24v. I have enough work for now, so it's on my future nice to have list. As it is, I'm already swapping out the old contactor to add reversing, adding wireless controls and making my own chain counter...
