Interconnecting batteries in series or parallel is totally feasible. But its best to know how it works – and the limitations of each. Collyn Rivers explains.
Batteries & Battery Charging
AGM batteries for caravans – they are still worth using
AGM batteries for caravans, camper trailers, motor homes charge faster and deeper than lead acids and are more rugged mechanically and electrically. They have far less internal discharge. If initially fully charged, they retain 60% or more for over 12 months (except in very hot areas).
How long can lead acid batteries last
How long can lead acid batteries last affects millions. Most written and believed, however has little factual basis. What people really buy are amp hours
Australian Battery Breakthrough
Gelion is in an exciting phase of its development program for battery systems. With their London-based counterparts, they are well advanced in planning their commercialisation and supply-chain strategies from initial prototypes all the way through to demonstrating commercial production capacity this year (2020).
Gelion’s small, low-cost battery cells can be used in flexible configurations, depending on the required applications. This could range from street lights, domestic use, commercial buildings and grid support.
RV Alternator Charging Problems
Before 2000 or so most alternators produced 14.4 – 14.7 volts, and a few close to 15 volts. This situation changed in 2014 in the quest to reduce emissions. Reducing alternator voltage assists, but introduces problems if the alternator also charges RV batteries. This article by Collyn Rivers explains what causes these alternator charging problems – and how to fix them.
Electrolysis corrosion in vehicles – how to find and fix it
Electrolysis corrosion in vehicles eats away engine and particularly cooling system parts such as water pumps. It is often caused by a broken earthing lead. These are often accidentally disconnected, or broken. If so, return current travels through components such as the radiator cooling system. Also metal around them. This corrodes parts that have dissimilar metals.
RV Batteries
RV batteries store energy from your RV’s or tow vehicle’s alternator and solar modules and grid or generator power via a battery charger. This article explains all about the many types of battery now available.
Lithium battery safety in caravans – are they all the same?
Lithium battery safety in caravans is tainted by a fire-prone technology of differing kind. The LiFePO4s used in caravans are far safer – here’s why.
Caravan and Motorhome Electrics
Caravan and Motorhome Electrics covers every aspect of designing, installing and fault finding of the electrics in fifth wheel and conventional , camper trailers and motorhomes. The book explains how things work, and what they do (not what vendors claim they...
12 volts dc from 24 volts dc
Taking 12 volts dc from 24 volts dc can ruin the batteries in a 24 volt system. Here’s how to do it effectively and safely. There are two main ways. The choice depends mainly on the peak current needed: for example the plus 130 amps for a typical microwave oven limits choice to the equalising system described below.
