  • Post in thread: Why shouldn't I buy a 120AH Deep Cycle Battery at COSTCO for half the price of a GEL ?

    Problem is for those in Canada. They are getting bent over on price compared to us price. The OP seems to be pricing from the north. $375 for us $800cad At that rate,,, I’d probably opt for a few years of FLA till it wasn’t stupid expensive just through price gouging.

    BTW Don't wait until the last few watts of lead acid are on their death bed. It takes a bit of change over to install lithium, if you do a build yourself you also have to take into account shipping time, upwards of 3 months. I installed my new batteries in my house as apposed to having them in...

    Try this on for size. Use Amazon US and ship it to Canada. Its 100 shipping and then the exchange rate. Beats the stupid Amazon.ca price

    The original question was why go with spendy gel when Costco has 150.00 FLA. It then turned into FLA vs LFP with a pinch of gel. I am guilty of a thread hijack I guess. But lead is so……. yesterday, ya know? It is absolutely valid to compare apples to oranges. If you think you can’t make a great...

    Easy answer, Because gel will beat the crap out of FLA Costco on every metric, unless you only need it to work for 6 months. Their idea of "Deep Cycle" and an actual Deep Cycle battery will not stand up to close comparison. Costco only expects 5% of the people to return their $150 battery. The...
  • Post in thread: 300A DC circuit breaker

    If I loose 5 batteries for any reason, it would be a total train wreck and I would hope the fuses blow. Voltage panel is located right next to front door so it is easy to just look, a habit we have developed over the years. LVDC is possible, but not likely. I am looking for a 2 wire auto start...

    Overkill with the app is very solid, the cell controls are great. If you need more output, set it up with a relay. Will has a good Utube vid on that. I’m going to set up 2 of my 10 that way so I can have extra draw when needed. And with a replace it even if you screw it up warranty.

    That is not inflation. It’s Capitalism. Charge as much as you can get away with. Raise price till people quit buying then reduce it so people think they are getting a deal. When in doubt read PT Barnum’s book.

    Toss in a few sleeping bags, inverter, tv and a tent and say you went camping. They won’t deliver to a locker, just tried. You’ll find any number of us just to the south that would receive and hold them.

    There is a butcher shop in Prince William that makes the best moose jerky on the planet. I’d drive to the border for a pound of that.

    There is an individual, in a position of authority, who regularly invokes the name of God as her commander. She has decided that "People with Wells, Septic systems or Solar Panels, should be paying Water, Sewer sand Power bills like everybody else" Also adding that each location should pay for...

    In 1985 I was building B1B’s at Rockwell in the Mojave desert. Thad = Tree Huggin A**Hole Democrat. Once a crappy nickname gets used it sticks, never the good ones. So I embraced it. I’m Don Sorry, no online documentation on construction. Too many jurisdictions disapprove of my lifestyle. I can...
  • Post in thread: Balancing for big (20kw) banks?

    The link you have indicated shipping extra. You should be able to get a cell around $90ish delivered with no extra duty ect. Ali is like the markets in Marrakesh. Back and forth bargaining.

    Unless you have something like "1" battery, fractional C rate charging is all you are likely to achieve. By fractional I mean well below .5C At that .5C on a BB 100Ah battery is still 50 amps at 14v DC. That would be a minimum of 800 watts of solar panels installed, probably needs 900w to get a...
