main components I decided to use, were a pair of Sealed Lead Acid (SLA)
batteries 12Vdc 1.2Ah each and a Yuasa 300mAh 24v charger. The charger
will be connected with the batteries in series. It is a three stage
charger ending in a trickle or float charge and will fully charge in
about 10hours (overnight). Notice the neat little volt meters.
