I provide some stage lighting and video/laser equipment for rent and offer custom content for them on demand.
Sometimes customers want to see the device in action in a location where there is no power source nearby.
I’ve already asked the manufacturer of my laser light equipment to include a rechareable battery in one of the laser projectrors to use that one for presentations.
He’s put a 1000W 12v-220v inverter in it and a 10,000 mAh li-ion battery which allows to use the device with no power cable attached and it can be recharged. Hes also put a volt meter to have an idea how much battery life is left.
Now I’m thinking of putting these parts in a custom case and using that box to power any of my devices like this.
What do I need? Just a 10,000-20,000 mAh li-ion battery pack properly connected to a 1000W+ inverter, with a voltmeter on the cables that go from the battery to the inverter? Or something more?
Can I charge the li-ion while the inverter is on and the device is consuming power? I can do that with my laser projector right now, but I don’t know if the manufacturer has added something extra for that to work right.
