6個。由于32a的(de)電(dian)池(chi)(chi)(chi)單(dan)只是12V32a，老蘆(lu)所以72v32a就(jiu)需要單(dan)只12V32a的(de)電(dian)池(chi)(chi)(chi)6個串聯起來，72v32a在兩輪車上(shang)己經(jing)是電(dian)壓最(zui)高，容量最(zui)大的(de)電(dian)池(chi)(chi)(chi)。電(dian)瓶是電(dian)池(chi)(chi)(chi)的(de)一種，侍臘帶(dai)也叫蓄(xu)電(dian)池(chi)(chi)(chi)，是指放(fang)電(dian)后經(jing)過充電(dian)可以繼續使(shi)用的(de)電(dian)池(chi)(chi)(chi)，有鉛(qian)蓄(xu)電(dian)池(chi)(chi)(chi)、鎳(nie)鐵蓄(xu)電(dian)池(chi)(chi)(chi)和鎳(nie)鎘局返蓄(xu)電(dian)池(chi)(chi)(chi)等。
