When Terras , using Panasonic ternary lithium batteries, created a magic tale to navigate exceed 400miles, Chinese factories are crazy with ternary lithium batteries research and developing and manufacturing.
Which one is better? Let me answer you in technical parameters as below:
LiFePo4, has good advantages in cycle life and high temperature performance, but poor performed in low temperature and especially in volume size and weight.
So my result is suggest to choose the best quality and price ratio according to your application intend use, and affordability.
Lead Acid Battery
Voltage fluctuation in working
Remains stable with different output
Voltage fluctuation based on output
500 ~700 cycles
(Residual capacity over 5%)
Very stable and very little affection by output current
Suffer a big affection in by output current. Capacity will be much smaller than rated capacity when output current is large.
Depth Of Discharge (D.O.D.)
50% ~ 60%
Self discharge rate (per month)
1~1.5% (Capacity remains over 80% even the battery is idled for one year)
30% (Battery capacity drops near to zero if it is unused for 3 months)
Fast charge capability
Charge to full capacity in about 6 hours
It needs 8 ~ 12 hours to fully charge the battery
Discharge working temperature ℃
Weight (Compare to the same capacity)
1/4 of weight to lead acid battery
comparatively heavier weight
Upright position is necessary
with built-in safety protection function
Dangerous of acid leakage
Conforms to RoHs standard
Violet RoHs standard；Lead and sulphate acid are pollutant
Disposition of used battery
Lithium-ion batteries are generally not considered an environmental hazard because they do not contain lithium metal. The United States government labels them as non-hazardous waste and does not oppose them being discarded together with the trash that makes up the local waste stream.
Needs special recycle, after treatment utility
