12.8V 9Ah E-Bicycle Battery Smart BMS Deepcycle Lithium Battery Pack
Know about lithium battery
Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable.
Why you need a bluetooth battery pack?
The battery pack is built in BMS,which can protect the BMS,including over charge protection,over voltage protection,over current protection,short circuit protection,balance function,over heat protection.
You can watch the battery spec through the APP on mobile phone,being connected by bluetooth BMS.
Lithium battery pack,why Deligreen?
Lithium battery pack is a system of lithium batteries,containg lithium battery,BMS,outer box.Battery pack is widely used in many applications,such as RV,caravan,solar system,camping,energy storage system,Led street lamp,golf cart,marine,boat,e-car,motorcycle etc.
Battery pack needs to be customized,before placing the order,we need some important parameter.ex.
