Why?
why? why do you want to keep havin to manualy charge a battery when a split charge system is so easy to fit and doesnt cost anymore than £40.
The split charge system does all the work for you, who wants to get home every other evening and then have to either take the battery out to charge it or mess around connecting it up.
anyone who messes around in that way must be mad,why bother?
£40 and such an easy fit ?
