What should be avoided when charging
lithium iron phosphate batteries?
1. Use a charger that is not compatible with LiFePO4 batteries to charge the battery.
Using chargers designed specifically for other types of lithium batteries or lead-acid batteries may lead to overcharging, undercharging, or imbalance, resulting in reduced capacity, shortened cycle life, or safety hazards.
2. Charge the battery at temperatures below 0 ° C/32 ° F or above 45 ° C/113 ° F.
Charging a battery at extreme temperatures may cause irreversible damage to its internal structure and chemical composition, leading to capacity loss, increased internal resistance, or thermal runaway. You should always charge the battery within the recommended temperature range specified by the manufacturer. When you follow this step, how long it takes for
LiFePO4 batteries to charge will no longer be an important issue. This is because charging at the appropriate temperature can lead to better charging.
3. When the battery is deeply or excessively discharged, please charge it.
If the battery voltage is below the minimum limit (usually around 2.5 volts per battery), please charge it as soon as possible to prevent further degradation. If the voltage of the battery is below the cutoff limit (usually around 2 volts per battery), you may not be able to charge it at all and may need to replace the battery.
4. Charge the battery in series or parallel without proper protection or balance.
Assuming you connect multiple batteries in series or parallel to increase voltage or capacity. In this case, you must use a Battery Management System (BMS) or balancer to monitor and control the voltage and current of individual batteries. Otherwise, it may lead to overcharging, undercharging, or imbalance of the battery, thereby damaging the battery or causing safety issues.
