Battery Transfer pump for antifreeze

I use a manual pump to winterize my class c, works ok, but thought I would see if a battery powered transfer pump that would connect my RV was available.
So far I haven't found one - anyone tried such?

After blowing out the lines with compressed air, I disconnect a pump fitting to let any remaining water drain. Then we open all the faucets and pour antifreeze in the toilet and all the drains. No pump needed.
