Good morning everyone. I hope you're looking back over a great week (mine was mostly outdoors!)
There's a portable power unit that's becoming popular with crews in the DC area - 'Jackery'. The unit I have been assigned by my client (model 1500) is heavy, and I note that it generates 110 V AC at it's outputs. I am wondering why I can't take a compact (eg : Group XX') Pb-acid battery and just run out 12 V DC via individual cables. (skipping over significant losses, in the Jackery probably following 14.xx V DC from LiON @ source -> 110 V AC via inverter, then back to 12 V DC after device's individual power supplies deliver to device inputs)
2 questions on that idea :
a. What are the pitfalls of delivering 12 V DC direct from posts? Is voltage regulation needed?
b. Does anyone have a contact person that might make these at their bench?
And that's about the limit of my technical knowledge. I do currently have a fresh 24 V Pb-acid battery here that is designed for kid's electric toys, really small, and that would be another option, while it would involved DC -> DC reduction at the posts. I am comfortable making my own video and audio cables, but I am leery of soldering up joints that will have high current flows thru them (too easy to blow stuff up!).
Enjoy your weekend,
Grant.
