The Renogy one has a current-limiting feature that cuts the current to half. Don't know about other ones.
"The DC-DC battery chargers feature 50% current limiting from the rated specification when connecting the LC Terminal to a 12V source. Current Limiting is instant and recommended to be connected to the same location as the D+ ignition cable. Alternatively, you can toggle
current limiting to your liking by connecting the LC terminal to starter battery positive terminal. In this fashion, current limiting will always take until removing the LC wire from the battery terminal to revert to the normal amp rating. Use 18-16AWG copper cable for the LC terminal
and you may need to splice your own connections for the other cable end depending on your connection point. "
I am not clear on the issue in the above post with the Victron or what other reason you would want to limit the current. It could be like other chargers, if it does more than the battery spec allows, such as more than 30% on an AGM. I had to not use my 55 amp converter on a single 100AH batt for that reason, but it was ok with two 100s in parallel.
