Havenโt used them but they seem legit.
Cost wise, consider MightyMax 200H 6v SLA as well. Theyโre about $80 cheaper a piece. I had good luck with them.
(Note I went with those out of necessity as there are/were very few 200a class 6v batteries that were short enough to fit in the battery compartment on our old TC.)
Theyโre about 5 years old and still going strong according to the new owner of our old camper.
