Electronics suppliers - Surrey/Langley - DIY Battery Backup

[mike31154]

Deep cycle 12 volt battery, alligator clips, mini DC connector to fit the VorTech controller backup receptacle and a battery charger/charge controller. Not sure you even need an electronics supplier for those parts. You could go a step further & hook two 12 volt deep cycle batteries in series to get 24 volts, use an extra relay to sense when power is lost & switch to battery power. This way your 'backup' could run the pumps at full speed. You'd have to ensure the batteries are well ventilated during the charging process if using lead acid, flooded deep cycle batteries though.
