This is a guest article written by Alan Knight, one of the more frequent contributors to this website. What Happens to Batteries when you Overcharge them? Do not attempt to charge a 12v battery with anything other than a 12v charger, whether it is a flooded unit, Sealed Lead Acid (SLA), gel or AGM. SLA…

When you’ve decided to go camping for the weekend…whether it’s in your own backyard or out at the lake, you need a tent that can give you both comfort and protection from the outdoors….
Recently George asked in the comments on our article about connecting batteries in series and parallel at the same time how he could make 36 volts from 12 volt batteries, while at the same time make the capacity (amp hours) add together so that each 12 Ah cell would combine to make at 36 Ah…
We received a question from Michael Correale today asking for some help on wiring his 24 volt horn to his 12 volt boat electrical system. Here is what he wrote: Ok, I am that guy who had to go and buy the 24 volt horn for my boat with a pre-existing 12 volt system. I…
Yesterday freegeographytools.com (a great resource if you’re interested in mapping, GPS, and GIS applications – they offer a lot of insights and opinions on various free software) wrote the first article in a series on building an inexpensive GeoPad. They are defining a GeoPad as a small touchscreen computer, field ready, loaded with built-in GPS…
One of our recent customers to purchase our South American Topographic Maps Series 2 which covers almost all of Brazil (as well as most of Peru and parts of Bolivia) had a few questions for us after downloading the 124 maps from the OverlandResource.com client download center (you can do the same by purchasing the…

If you are building an off-grid power system you probably need to start building a battery bank. And one of the first questions you’ll have is how many batteries do you need. To answer that question you need to start by understanding the capacity of batteries. This article explains what is meant by the Amp-Hour rating of a battery.
You need to increase the amp hours available from a battery bank as well as the voltage. This article shows you how!
