New MINI Lithium Batteries January 25, 2025, 12:20:13 am Hi Folks,I finally had to replace the AGM original batteries on my 2016 MB. Found these Wattcycle brand mini size 100AH lithium batteries for a good price.Was able to fit 3 in the battery compartment without any cutting or modifications. I added a Victron smart shunt and still need to order and install an Victron Orion 50amp DC to DC converter to go in the alternator charge line to the batteries.I did install some small 12 volt bee keeping heater mats underneath each battery to keep them above freezing. They have low temp protection in the BMS, but I can heat them as needed by inserting a fuse into the fuse holder. Will probably put a toggle switch in instead. I did upgrade the converter to a 75amp PowerMax PM4, was able to fit it in the old parallax lower housing. 4 Likes
