Hi All,

These might be of interest to folks with solar and motorized RV's to keep the starter battery topped up.

https://www.amazon.com/gp/product/B07WY4........_yo_dt_b_asin_image_o02_s00?ie=UTF8&th=1

They come in sizes from input of 8 / 40 to output of12 volts 3 amps and up to 48 volts input to output of 12 volts 20 amps. All are less than 100 bucks.

Trik-L-Start would work--but they do NOT ship to Canada. (and are a heck of a lot more money).

I think I'll get one for keeping my generator battery charged in storage.

The specs. for that device calls for an output of 12V DC +/- 2%. That's probably not a good battery charge voltage? darn!
Maybe something like this would work.
Dork has alsorts of DC to DC devices on Amazon.

Caution - I have a few of these devices and am NOT impressed (20amp, 6amp and a 3amp). The 20amp one has huge AC spikes on the 12.35Vdc output. Output regulation is OK at best with the boost / buck conversion. They will not operate an IP camera with their excessive AC spikes which are at 500mmsec intervals. Used a 20volt Dewalt tool battery and gave up.

I had a couple of these in the 48V to 12V version, and they're junk. Using Victron Orions now.

If you want a 12V battery CHARGER from a higher DC voltage source, spend the money and buy something to do the job !

theoldwizard1,

I want something that will power the remote start on the generator without killing the battery.
