A cylindrical lithium battery is a battery with a high capacity, a long cycle life, and a wide operating environment temperature. Products are used in solar lamps, lawn lamps, backup energy, power tools, toy models, and photovoltaic energy. Cylindrical lithium batteries are divided into lithium iron phosphate, lithium cobaltate, lithium manganate, cobalt and manganese, and ternary materials. The outer shell is divided into steel shell and polymer. Different material system batteries have different advantages. Mainly steel-cylinder cylindrical lithium iron phosphate battery, iron lithium battery performance is high capacity, high output voltage, good charge and discharge cycle performance, stable output voltage, high current discharge, electrochemical stability, safety in use (not It will cause combustion or explosion due to improper operation such as overcharging, overdischarging and short circuit. It has a wide operating temperature range and is environmentally friendly.

Q1: Can Advance Energy ship battery out of China?
A1: Yes, we can ship to any country out of China, you can tell us your address to check.
Q2: Can we put different LiFePO4 battery pack in parallel or series by ourself?
A2: 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.
Q3: Can we put different LiFePO4 battery pack in series by ourself?
A3: You can buy big voltage directly from us.We suggest do not out them in series by yourself,this will hurt the cycle life of the pack.
Q4: Does your battery pack include BMS? Can we use it for car?
A4: Yes, our battery pack include BMS, you can use it for low speed car only or aux. power for standard car. Do not use it for standard car directly, that will need more complex design BMS for the pack.
