Rechargeable 8S12P LiFePO4 Battery 24V 40Ah for Solar Street Light
Lithium-ion batteries for stand-alone applications
Lithium-ion battery technology in stand-alone applications provides
high operating life, very low maintenance, and lower operating
costs than standard battery technologies.
LFP (LiFePO4) technology, which can operate over wide temperature
ranges, is a consistent choice when return on investment is a key
element of a project.
Standalone batteries are typically based on
lithium-Ferro-Phosphate, due to their long service life and small
footprint.
We offers a range of 12V, 24V and 48V Lithium-Ion battery pack to
meet most of our customer needs.
Major advantages of Lithium Iron Phosphate:
Very safe and secure technology (No Thermal Runaway)
Very low toxicity for environment (use of iron, graphite and
phosphate)
Calendar life > 10 ans
Cycle life : from 2000 to several thousand (see chart below)
Operational temperature range :up to 70°C
Very low internal resistance. Stability or even decline over the
cycles.
Constant power throughout the discharge range
Ease of recycling
Life-cycle ofLithium Iron Phosphate technology (LiFePO4)
Lithium Iron Phosphate technology is that which allows the greatest
number of charge / discharge cycles. That is why this technology is
mainly adopted in stationary energy storage systems
(self-consumption, Off-Grid, UPS, etc.) for applications requiring
long life.
The actual number of cycles that can be performed depends on
several factors:
Level of power in C-Rate
Depth of Discharge (DOD)
Operational environment : temperature, humidity, etc.
In standard environment, and for 1C cycles, the below life cycle
estimation for LFP :
2000 cycles at 100% DoD
3000 cycles at 80% DoD
8000 cycles at 55% DoD

Warnings
Do not immerse the battery in water or seawater, keep the battery
stands by in a cool dry surrounding.
Does not use or leave the battery near a heat source as fire or
heater.
Use the battery charger specifically for that purpose when
recharging.
Do not reverse the position and negative terminals.
Do not connect the battery electrodes to an electrical outlet.
Do not discard the battery in fire or a heater.
Do not short-circuit the battery by directly connecting the
positive and negative terminals with metal objects.
Do not transport or store the battery together with metal objects
such as hairpins, necklaces, etc.
Do not strike, trample or throw the battery.
Do not directly solder the battery and pierce the battery with a
nail or other sharp objects.
