The global economy is undergoing a transition from carbon-intensive energy resources to low-carbon energy resources, switching from fossil fuels with harm to the environment to cleaner and alternative renewable energy sources. Lithium ion batteries as the most favorable electrochemical energy storage system are widely used in many fields due to high energy density, excellent self-discharging rate, high operation voltage, long cycle life, and no memory effect. The application fields include not limiting trucks, cars, buses, golf carts, AGV, material handling equipment(forklifts), as the driving force, and various energy storage systems.

Lifepo4 50Ah Battery Features
Significant weight reduction
Lifepo4 50Ah Battery is 70% lighter than lead-acid batteries of the same size.
Direction
It can be installed and operated in any direction. No liquid spilled.
Fast charging
50ah lithium ion battery can be fully charged in a shorter time than lead-acid batteries.
No voltage drop
50ah lithium ion battery maintains a higher voltage during high current use, and provides more power when you need it most.
Charging efficiency
When charging a lead-acid battery, the energy between the charger and the battery may lose 15-30% due to heat loss. The efficiency of the 50ah lithium ion battery is 99.1%, and it can accept nearly 100% of the power from the charger or solar panel.
No self-discharge
The monthly self-discharge of 50ah lithium ion battery is less than 3%. The 50ah lithium ion battery can be fully charged for more than 1 year and hardly self-discharge. Due to self-discharge, lead batteries lose up to 30% of their capacity per month.
Anti-vibration
50ah lithium ion battery is bolted together and made of solid structure.
Temperature proof
50ah lithium ion battery is stable at both high temperature and low temperature. (-4F-140F working temperature)
Higher energy density
The energy density is 4 times higher than that of lead batteries.
Excellent "usable" capacity
50ah lithium ion battery can be fully discharged without damaging the battery.
Battery: The 50ah lithium ion battery consists of a square lithium iron phosphate battery designed to meet the VDA size standard. Each battery is designed with explosion-proof stainless steel casing, flame-retardant electrolyte and built-in thermal fuse.
Design
The 50ah lithium ion battery is connected by bolts to improve the strength, conductivity and quality of our LiFePO4 battery. The battery is bolted through the longitudinal circuit board to provide balance and short-circuit protection. In the event of one or more battery cell failures, the circuit board will take the battery cell offline and allow the battery to continue to work normally under 12V voltage, but the capacity will be reduced.
Balance
When constructing each battery pack, 50ah lithium ion batteries are grouped together according to 10 items of consistency. The bolted battery design provides a stronger connection, which reduces resistance and improves current conductivity. In addition to passive balancing through vertical circuit boards, these batteries maintain the highest overall battery pack capacity and are designed to last more than 4000 cycles.
Reliability
Thousands of 50ah lithium ion batteries are used in commercial, government, entertainment and military applications all over the world.
