6Ah lead acid replacement rechargeable lithium ion battery pack DIY for e-bike
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.
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.
This is the requirement/customized sheet for you to fill in to get a most precise price.

Features
◆ Using the technology of lithium iron phosphate cell, superior safety,thousands of cycles, 100%DOD, under normal conditions.
◆ Built-in automatic protection for over-charge, over discharge, over current and over temperature.
Free of maintenance.
◆ Internal cell balancing.
◆ Lighter weight: About 40% ~50% of the weight of a comparable lead acid battery.
◆ Can be charged using most standard lead-acid charges (set).
◆ Wider temperature range:-20C~60C.
Support for Series application expansion (up to 51 .2V) and two in parallel.
Lithium battery is the trend to replace the lead acid battery.

Lithium battery pack is with more than 2000 cycles life,lead acid battery is only with around 500 cycles,you need to buy 3-4 lead acid battery that as long life as lithium battery.
Lead acid battry is much bigger and heavier than lithium battery,lithium battery pack is used in more applications.

FAQ
Q: What is the life expectancy of a Lithium battery?
A: The typical estimated life of the Lithium Iron Phosphate
(LiFePO4) battery is 5-15 years or 2000 to 8000 charge cycles. One
charge cycle is a period of use from fully charged, to fully
discharged, and fully recharged again.
