Advantages of 80 Series Battery
Less degradation & long life
Lifepo4 has a long life cycle as compared to other batteries and has 1,000-10,000 cycles. Lithium iron phosphate has an excellent discharge rate and has less degradation at high temperatures. Because of their extended life features, you can use these batteries for various applications. A standard qualified lifepo4 battery remains 80% dod till 2000 cycles of discharging and charging.


No harm to the environment
80 Series battery are eco-friendly and do not contain harmful metals. They are non-contaminating and non-toxic and are less costly than other lithium-ion and lithium polymer batteries.
Compact size & lightweight
80 Series battery have a compact size and high power density. They are lightweight and have no memory effect. 80 series battery don’t require priming, and less maintenance is required for their care. They are gaining fame due to their small size, lightweight, stability at high temperatures and low cost.


High safety & efficiency
No downtime and fast charging make lithium iron phosphate more efficient and safe to use. These batteries can deliver a high discharge pulse rate in a short time and have constant discharge voltage. The chemical and thermal stability make 80 series batterymore reliable and safe.
Withstand extreme weather condition & temperature
These batteries can withstand extreme weather conditions and temperature, and the battery remains cool at high temperatures. They don’t have thermal runaways and don’t explode when they overheat or overcharge.


Good storage & suitable for various applications
80 Series battery use for various applications such as electronic machines, military, medical applications, and electric motors. For a cheap battery alternative, these batteries can be a good choice. Safe iron phosphate chemistry and no recycling procedure make these batteries cheaper than lipo and li-ion batteries.
