I'm not exactly sure the specs on the battery but I recently burned up my stock 90A alt big three and xp975 in back. Although it could have been on its way out as y charging voltage was 13.6 but regardless you'll need to charge up the battery's often with that little alt and the pull your amps asking for.
Thanks for your answer:)
