I'm currently using a 12v 32ah leisure battery to power my mobile setup. I've installed it in a box, connected an inline fuse to 2 x car type power outputs, a USB3 socket and a voltage display.
The battery is kept on constant trickle charge using a CTEK MXS 5.0 Battery Charger and shows in the region of 12.4 volts when first switched on. To this I'm connecting a NEQ6 Mount, 2 x small dew heaters and a ZWO ASIPLUS. The plus has a ZWO ASI294 main camera, a ASI120 mini guide camera, an EFW and an EAF attached.
The issue i'm having is that the ASI keeps showing a low power alert and on checking its often registering down to 10.8 volts, way below what i expect to see. Looking at similar setups the battery should easily be able to cope with the load.
Any thoughts as to why i'm seeing this issue.
