RV supply cables – choices of current capacity and length
This article shows the sizes and lengths of electric supply cables for caravans and motor homes legally required in Australia and NZ.
Fast battery charging from generators – cheap, effective and relatively simply
Speeding battery charging from generators is cheap, effective and relatively simple. This article by RV Books’ Collyn Rivers explains how to do it.
Dc-dc charging – how to speed alternator charging
Initial charging of a deeply discharged battery is generally limited to a basic dc-dc charger’s capacity: not the alternator’s. Dc-dc chargers under 20 amps thus usually take longer to charge close to flat batteries to half charge. Thereon, charging is hugely faster.
Battery charging and battery chargers – how to do it properly
Battery charging and battery chargers are often misunderstood – causing batteries to die before their time. This article explains why and how to avoid it.
RV electrical wiring – twin-wire or chassis return – here’s why twin-wire is usually better
Twelve-volt caravan systems may be twin-wire or chassis return. Twin-wire is usually best. This article explains why – and which to choose to avoid problems.
Connecting caravan batteries – there’s no magic way of doing it!
Connecting caravan batteries is often misunderstood. This article explains what’s possible, and why and how to do it successfully.
Battery ventilation is vital – why take any risk?
All lead acid batteries, AGMs and gel cells, generate explosive gas. Even though most are sealed, makers stress that battery ventilation is vital still. Confusion exists over this. Around 2000, some battery makers began to claim that no ventilation was required. Or, ventilation, is advisable but not necessarily essential. They withdrew this advice, however, shortly after. Many batteries thus have a warning notice as below.
Variable voltage alternator problems with caravans – how to fix
Variable voltage alternator problems with caravans and motor homes arise when charging auxiliary batteries. Here’s why and how to fix them. These alternators are, in particular, installed on many post-2013 vehicles.
