I have a 1/2 ton truck which has a 270-amp alternator and is rated 170 amp at idle. I added a fused wires(dedicated ground wire) from the battery of the truck to an Anderson connector at the back of my truck and ran additional wiring to a Victron 360-watt DC-DC converter mounted in my RV. The...

Ah, Good point, depends on what you need for your application. If you have a one or two hour generator window at a campground, then I get you on the need for fast charging. That is why defining what your specific application is helps in deciding what you need. Battery charging rate is like...

Very good point. Why don't you just use an atttiny(arduino compatible) series chip, which consumes a few milliamps. Your battery would last for months and no solar needed.

Each cell is different, so they can have different charge rates, discharge rates. So, there is a range. Just look at the specs on the battery per the manufacturer, and that will give you the answer. It can get confusing and overwhelming. It is just best to define what you want your system to...

Provide some more information on your project such as the length of your wire runs, components, etc. For lower voltage DC applications, the length of wire run has a bearing on the proper gauge(size) of wire to use. Will has some excellent videos on the correct gauge of wire to use and how to...

Can you clarify how much current, voltage, 3 connections? Good source=Auto parts store. Often switching lower voltage, high current through a switch is better done through a relay wired to a switch.

That's the most reliable and probably safest, but higher current Anderson connectors would work and be easy to apply and allow you to switch. You could also use a boat battery selector switch. They can handle high current. Connect the grounds together, but the only danger is if you accidently...

The greater the number of connections, the greater the potential voltage drop. When you are talking high current loads it is best to use the most solid and stable connections imho. All it takes is even a momentary poor connection with high current draw and things get hot very quickly. It also...

I have the progressive dynamics 80amp charger. PD says a 20 amp circuit is needed, so I had to run 12ga for a 20 amp outlet as my camper has only 15 amp outlets. I charge two batteries with it, so it is a reasonable charge rate. I have been very happy with this charger. It has sat out in...

I just bought two of the 200Ah batteries from Newt on Amazon. Can't beat the price, but you get what you pay for. I am currently testing them. They seem to have close to the rated capacity(I tested with intermittent low and high drain to emulate my use scenario, so that probably was the...
