Well, I have always gone my own way, and with powering my gear it has
worked very well.
I bought my first scope nearly 69 yrs ago, but it was manually operated.
My first powered scope came along some 5yrs later, and I operated it with a motor cycle battery for several yrs. I then bought a more power hungry rig,
and bought a car battery to power it, which it did satisfactorily for, from memory, about 7 yrs. When my car battery became too weak to crank the car over on cold winter mornings, I relegated it to powering my rig, which it did for about 4 yrs before finally giving up the ghost. I have powered all my rigs
ever since with my retired car batteries, so have spent a grand total of the cost of one car battery over the last 54 yrs. One happy camper.
Pop down to your local auto leccy; they usually have a number of batteries
laying around that have been discarded when doing single to twin battery
conversions on 4WDs. These are usually around 80amp/hr, and will run your rig for years. The good news is that they often give them away, or maybe charge $20 or so, and will load test them first.
