| I’ve added a battery backup to my sport as the main power switch seems a little weak and I don’t want to pay another £25 once a year to change my switch.
I’ve used a small 300mah 4.8v backup battey with the backup unit I got from ebay, works a treat. Just plug in switch everything on, then unplug your main battery. The backup light comes on but there isn’t even a glitch from the power supply, it just runs off the backup. It’s a very smart system.
