FAQ:
1. What is the 12.8V Li FePO4 battery?
The 12.8V Lithium Iron Phosphate (LiFePO4) battery is a type of lithium-ion battery known
for their long design life, good cycling capabilities and importantly their safety.
Lithium Iron phosphate or LFP is the short term for LiFePO4. LiFePO4 is proved to be a safe
technology to compare with other lithium-ion batteries.
Other types of lithium-Ion batteries are:
Lithium Cobalt Oxide (LCO)
Lithium Manganese Oxide (LMO)
Lithium Nickel Manganese Cobalt (NMC)
Lithium Nickel Cobalt Aluminium Oxide (NCA)
2. What chargers should I use to charge the 12.8v LFP battery?
Please note that LFP batteries have a different nominal voltage. Although they are made to 12V
battery standard, the charging and discharging curve is different, A specified LFP battery charger is required to recharge the battery. If the battery charger does Not specify LFP, please check the specification of the charger to see if it can meet the charge curve on the datasheet. LFP batteries need a higher voltage and long time during the bulk stage than a lead-acid bulk stage. Also, check with the supplier of the charger to see if it can charge an LFP battery.
Please note that some chargers have a tag saying Li-ion, there are different Li-ion batteries, a LFP battery has a different Voltage compared to other Li-ion chemistry, a "Li-ion" charger may not be suitable for an LFP battery, check with the charger's supplier.
A charger that can bulk charge the battery to 14.4V will be suitable for the LFP.
LFP needs a Constant Current/ Constant Voltage (or we called bulk/absorption) method to be fully
charged. And any rejuvenation or pulse current must be disabled. Only 3-stage is required. Please
also DO NOT float charge the battery for the long term.
3. What are the functions of the Battery Management System?
BMS is built into the battery system, which is responsible for collecting and analyzing the battery
performance. The BMS monitors the voltage, temperature, and current of the single cells. The key
function is to protect the lithium batteries and reduce the risk of damaging the battery. The BMS
protects the LFP battery against over-voltage, under-voltage, high temperature, low temperature,
and internal short circuits. The BMS also balances the charge of each individual cell.
Please note that the BMS is designed to protect the battery from any abuse. Normal operation
should not trigger any protection. If any protection happens, leave the battery disconnected for
a period and the battery protection will be released once it goes back to normal. Then do a
recharge if the battery was over-discharged or stop charging if the battery is over-charged.
4. If I buy a 12v 100ah LFP battery, would I expect a longer life than the lead-acid 12v100ah?
Generally, LFP has a huge advantage on life expectancy over a lead-acid battery.
The datasheet shows that 50% DOD cycles will be around 4000 when it degrades to 80%
5. Should I charge my LFP battery before I use it for the first time?
Yes. LFP batteries have less than 50% charged (SOC) from the factory for safe handling and
transportation. This means the battery is not ready to use until it has been fully charged. It is
imperative to charge the LFP battery with an approved LFP-rated charger before using it.
6. How can I get the most power out of my LFP battery?
Using a proper charger and proper cut-off device is ideal to get the most power out of the LFP
battery. The maximum discharge current is stated on the datasheet. Please check the datasheet
before use.
7. Can I discharge the LFP battery to 100% DOD?
Yes, however, a safety cut-off voltage is required to be set as when the battery voltage drops to
the cut-off, the battery is fully discharged. (cut-off 11.2V recommended)
