I was going to use 2 of them. As they are 8.4ish volts for two. A 9v battery is usually not 9v. Some are around 8.3v like the rechargeable 9v batteries. I can put this together for around $5. As I have a bunch of the 18650 batteries and the charger already. Plus the capacity of the 18650 is way higher than the 9v also so I would not have to change them out as often.

Going to order the battery case soon and change it over this winter. Then have it ready to go this spring. But I will test it out in the house leaveing it on to see how long it takes to drain the battery down.
