1. Product Introduction of 48V Lithium Ion Battery
This product is a ternary lithium battery pack produced by Chilwee company, which is mainly used for electric bicycles with rated voltage of 48V and rated power ≤ 350W. The battery pack is composed of flexible cells in series (including protection board). The battery pack has the characteristics of green environmental protection, strong kinetic energy, high energy ratio, ultra long cycle life, safe use and so on.
Advantages of 48V lithium ion batteries
High energy density.
High open circuit voltage: with the change of electrode material, open circuit voltage up to 3.3~4.2V.
High output power: 300~1500W/kg (@20sec) according to different electrode materials.
No memory effect: lithium iron phosphate battery has no memory effect, the battery can be charged and discharged at any time, no discharge, easy to use and maintenance.
Low self-discharge: < 5% ~ 10% / month. Smart lithium-ion battery built-in monitoring circuit, the monitoring circuit of the operating current is even higher than the self-discharge current.
Wide operating temperature range: -20 ℃ ~ 60 ℃ can work normally.
