does anyone have the VK single logo auto battery?I need to know if its powerfull enough or equal to the manuels? I have 2 manuels now and they are great but want to try a automatic batt. I dont want the extra long batt in automatic figured id get manuel for that. Also how about the power of the no logo battery. Is that fairly powerful enough? also does anyone know the cutoffs of the single logo auto and the no logo auto batt. Thanks for any info.
