Yes. The battery can be put in parallel by customers. But there are few tips we need to pay attention:
<1> Make sure the voltage of each battery are same before put in parallel. If they are not same, charge them to the same rate;
<2> Do not put discharged battery and undischarged battery in parallel. This may reduce the capacity of the whole battery pack;
<3> Do not put the 12V batteries in series.
<4> If you are not professional in parallel batteries, please don't handle the battery by yourself. It may cause danger and hurt the cycle life of battery;
<5> If you want to make a higher capacity battery pack, like 72V 200Ah, please order 72V 200AH directly. The cost for one 72V 200AH is lower than two 72V 100AH pack. To charge or discharge one 72V 200Ah directly is better than to charge or discharge two 72V 100AH packs, cycle life longer, safer.
