I want to put together a portable 6000# winch to attach to a 2" receiver on my truck. The normal option is to buy a good sized deep cycle marine/RV lead acid and place it in a box, with some short wires. That might be the lowest cost option, but it is quite heavy. Are there any good options for using LiFePO? I see peak current being the big stumbling block, as the winch will likely draw 300+ amps and might spike to twice that for a second. Those little jump starter packs can easily deliver that current, but obviously not for any length of time (a couple of minutes). I would assume that there are batteries made for the start (SLI) market? To e this seems like a 100AH battery with a 6C discharge rating is what i am after? Thoughts?
Are there any good 12V LiFePO high current options for portable winch?
