Can someone please help me here.
At our station, we've had a firefighter install an ipad and connected it up to charge as the truck is on. On the ipad, he's setup an autostart app that opens our official CFA paging, mapping and verbal instructions (via google maps) on the route to drive. It's works really well. The only issue he is having is keeping the ipad charged when the truck is off. I'm worried about connecting it permanently whilst the ignition is off.
I've found to charge an ipad when flat is 2amps at 5V DC (10W).
Trickle charge once charged and in sleep mode - no idea - but that's what I'm looking at
Batteries on the trucks - two 12V batteries in series (CCA 650, RC 140, 75Ah).
I feel the battery would loose charge standing idle more that it would trickle charging. Can anyone please confirm.
