The charge indicator will be useless for any other type of battery, which by nature operate on different voltage. … Buy a real DVM, measure the actual voltage, and google up a table that shows voltage vs. state of charge for that battery type. …

Why are you making them out of metal??? Make them out of wood. Much easier to find a wood lathe than a metal lathe. Just cut it about 2mm short on the active ends, predrill a small hole, sink 2 …

Why not just hot-shot the equipment straight off battery? (perhaps at a different battery voltage). … Best practice is to size lead-acid battery banks so they normally do not use more than 25-33% of battery capacity. Yeah. Ouch. But the upside of lead-acid is it's cheap. …

So a lead-acid battery is a lousy choice for deep cycling generally. However, your car's starting battery is NOT optimized for deep-cycling. It is optimized for starting. … Mind you, learning the tech and using a Battery Management System is non-optional unless you like RV fires. Could we just have one "master battery" and dump the lead-acid starting battery? …

The typical reason is a very cheap battery charger that did not know how to charge the battery properly. Modern state-of-the-art battery chargers can charge lead-acid without any boil-off at all. … You can try refilling and recharging this battery. I would use a regular battery charger like one intended for an automobile battery. …

First there's no such thing as a 100-amp battery; however 100 amp-hour would be typical of a car-battery-sized thing. An amp-hour is an amp for an hour. … If you want a battery that does exactly what it says on the tin, try nickel-iron. And with a solar setup, you typically want a 3-day battery capacity to bridge you across cloudy/stormy days. …

The battery is fine. It's so totally your wires! … You need to replace those wires regardless, but I would look at a lower amperage vacuum cleaner before I'd look at increasing inverter/battery size. …

However, when one battery is charging, it is fine to tap that energy to charge another battery, using any of a variety of methods. … You don't want to be in a situation of leaving a battery partially discharged for any longer than necessary, because that ages a lead-acid battery. …

You can plug those in and get 2.66 amps at the battery. Inverter Inverters are magical things, but they're not free. It costs power simply to have them "spun up". … Amps of current on battery: 8.25 amps. Verdict Running things directly off the battery is much better. Shut that inverter off! …

The panels might output slightly more under absolutely ideal conditions, but those are rare. 70A into a 450 amp-hour battery means you would recharge them from zero in 6.5 hours (which you should not …

Sounds like you may be getting an education in how energy density works. The "20 per foot" LEDs you picked are more likely 300 per 5 metre, which is a standard size" and actually ~18 per foot. Th …

If your oh-so-clever adapter manages to put a lithium battery on a NiMH charger, you could have yourself a nice fire. …

What also goes in this panel is a battery charger whose job is to keep your battery bank at full charge and also power any loads on the battery-side system, so just like your car’s alternator, it runs … lights, radio and also recharges the battery. …

As far as sizing the system (how big solar vs how big battery vs loads), that is the usual place people go wrong, because they have not bothered to learn the concepts. It takes some time. … than 1/3 of a lead-acid battery's capacity", what a watt-hour is, how much common loads take (modern refrigerator: 1000 watt-hours per day), how to size solar panels to allow for winter and cloudy days, battery …

Note that 240V power has 20 times the force of a 12 volt battery. Amps is the flow/volume of electricity. Power (the thing you ultimately want) is pressure x flow, or volts x amps. …
