R1: Yes, we can ship to any country out of China, you can tell us your address to check. Q3. Can we put different Lithium battery pack in parallel or series by ourselves? R3: Yes. The battery can be put in parallel or series 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 Don't not put discharged battery and undischarged battery in parallel. This may reduce the capacity of the whole battery pack. 3 Advise us the target capacity of the whole pack if you would like to put them in series. We will choose the suitable BMS for each battery. 4 If you are not professional in parallel and series batteries, please don't handle the battery by yourself. It may cause danger and hurt the cycle life of battery.Lithium Battery factory website:http://www.hengchuangbattery.com/lithium-battery/
