>APPLICATION
Lithium Iron Phosphate (LiFePO4, LFP) is kind of Li-Ion rechargeable battery for high power applications, such as EV car , Power Tool and RC hobby. LFP cells feature with high discharging current, non explosive, long cycle life (>[email protected] rate, IEC Standard), but its energy density is lower than normal Li-Ion cell (Li-Co) (higher NiMH cell). Please visit our Knowledge on LiFePO4 battery to learn more detail. LFP cell has 3.2V nominal working voltage and shall be cut-off power at 3.6-3.8V per cell during charging. Please see the table below to see comparison between LFP and other rechargeable batteries. LFP battery has the lowest cost if considering its long cycle life.
| Chemistry | Voltage | Energy Density | Working Temp. | Cycle Life | Safety | Environmental | Cost based on cycle life x wh of SLA |
| LiFePO4 | 3.2V | >120 wh/kg | -20-60 °C | >2000(0.2C rate, IEC Standard) | Safe | Good | 0.15-0.25 lower than SLA |
| Lead acid | 2.0V | > 35wh/kg | -20 - 40°C | >200 | Safe | Not good | 1 |
| NiCd | 1.2V | > 40wh/kg | -20 - 50 °C | >1000 | Safe | Bad | 0.7 |
| NiMH | 1.2V | >80 wh/kg | -20 - 50 °C | >500 | Safe | Good | 1.2-1.4 |
| LiMnxNiyCozO2 | 3.7V | >160 wh/kg | -20 - 40 °C | >500 | better than LiCo | OK | 1.5-2.0 |
| LiCoO2 | 3.7V | >200 wh/kg | -20 - 60 °C | > 500 | Unsafe w/o PCM | OK | 1.5-2.0 |
Major parameters of protection board:
1. Overcharge protection: Starting protection in the voltage range of 15.0v -15.6v,resume normal under the voltage 15.0v.
2. Over discharge protection: Starting protection in the voltage range of 8.0v-8.4v,resume normal over 8.4v.
3. Short circuit protection: Starting protection when short circuit,switch off the load,resume normal.
4. Average voltage: average 3.6v voltage per cell.
Installation instructions:
1. Please check the recharge voltage of the vehicles. It can be installed in the voltage range of 13.5v to 14.8v.
2. It shows there is malfuction when the charge voltage is over 15.0v. Please install the batteries after overhauling.
3. Please check the battery voltage before installation. No need to charge when battery voltage is over 12.8v. Please charge the battery to over 13.6v-14.8v when the voltage is under 12.8v.
4. Please check the position of the positive and negative to avoid short circuit.
Charge and maintanence instructions:
* Please make a charge maintanence to keep the best performance when the LiFePo4 motorcycle batteries are leave unused for over 1 year.
Special Notice:
* LiFePo4 motorcycle battery is only used for starting the motorcycles or as the power of motorcycle related applications. There may be any danger or loss if for other applications,please be cautious.
