I have also used this same Gunson charger in automatic mode on my aircraft
battery (normal lead acid)and found it to be quick and effective. However,
I have always disconnected the aircraft cables from both the +ve and -ve
terminals of the battery prior to charging. Is this strictly necessary?
One other question concerns auxiliary power sockets for those occasions
where the battery has run down for some reason and you're far from a battery
charger. How do people wire such sockets up to the battery? Is it simply
direct to the terminals? What sort of socket do you use and where do you
mount it? Could such sockets also be used for trickle or fast charging the
battery without having to take the cowls off?
Any thoughts most welcome.

I always use an inexpensive automatic charger made by Gunsons. Available in
the UK for around 20 from Argos. I use it on all the Gas RC batteries we
sell as well as my own batteries on cars and aircraft. It delivers a high
charge to bring the battery up to charge and then reduces the charge
automatically until it virtually switches off. Far better than a trickle
charge and hardly any more expensive.
