How do batteries connected in parallel give more current than batteries

Yes, parallel batteries "can" supply twice the current when the load is less than the ESR of the battery. ( As shown above, for short circuit current, it is twice.) But otherwise, when the load is equal to battery ESR, the current is the same. With series cells it greater when the load R is higher than ESR, the higher V/R produces a higher current. OHm''s Law always works
