Hi there I recently bought an LS R4041 and made some add-ons like a 12,000lb winch and a front and back 400 watts total on bar lights, (not yet wired). I like to know if any of this charge could overwhelm my 80amps AGM battery, and if that's the case, if I should add a 22 amp second battery kit (XS Power XP750CK). NOTE: All are not to run a the same time. Thanks
