Wanted to provide a quick review here that any serious off roader should be aware of regarding the factory battery and installing winch systems.
I installed a Greenlane bumper with a Warn Evo 10-s 10,000 lb winch. I ran an over size 2A positive wire rated for 2000 watts from rear to front so power drop was not an issue. Full bumper review here - https://www.4runner6g.com/forum/thr...-review-read-before-you-buy.9751/#post-118584
Anyway, i attended a clients off grid location today and for the first time had to put my winch to work. My first experience was extremely underwhelming and frankly concerning.
I have been running winches for many years ranging between high end to low end 12,000 - 8000 lb systems. Currently the winch on my 6th Gen is a Warn Evo VR 10-S rated for 10,000 lbs. in all of my winch experiences, the failure cut off i experienced on this current set up was substantial. The winch would cut out after 4 seconds of pull and i can confirm it was not at the max 10,000 lb rating.
I want to clarify it was not a winch issue, it was a battery issue.
The factory battery was not able to provide the power needed to adequately operate the winch systems the cable im running is almost 4X oversized, the watt testing on the run showed a surge of 2000 with no power loss before installing winch systems so the cables im using are more then adequate and it is not a power loss issue in cable length.
In the end, i was only able to winch for about 4 seconds before the factory battery would fail to full depletion and cutout, would have to then wait for 30 seconds for the battery to recover before i could winch again for another 4 seconds.
I am almost positive i have cooked the factory battery from this 1 winch sessions so i am not even going to mess around and will be upgrading to an AGM Odyssey battery to ensure my winch systems are adequate going forward.
I will re visit this post after i upgrade the battery and do another winch session so other users can see if my battery swap rectified the issue.
Long and short, if you see anyone with a winch and want to confirm if they actually used it, just ask them if they have upgraded the battery on their truck, if its still factory, they aint actually off roading.
