If the load exceeds the battery’s limits, the protection system may shut the battery down to prevent damage. For more detail, see our guides to BMS protection and continuous vs peak current.

Battery performance can be affected by charge level, load size, temperature, cable setup, charger suitability, or system configuration. If performance issues continue, check the installation and operating conditions before assuming the battery is faulty.

This is usually caused by the BMS activating to protect the battery from overload, low voltage, or temperature limits. See our guide to BMS protection.

This is often due to the battery not being able to supply the required current, especially during startup. Learn more in our current ratings guide.

Battery runtime depends on load, depth of discharge, and system setup, and higher usage can reduce effective lifespan. See our depth of discharge guide.

Fast discharge is usually caused by higher-than-expected load or system inefficiencies. Learn how usage affects performance in our depth of discharge guide.

Voltage drop under load is often related to internal resistance or cable sizing within the system. See our voltage drop guide.

This is often caused by an incorrect charger, charging profile, or system setup. See our charging stages guide.

This can be due to charger incompatibility, low temperature protection, or the BMS preventing charging. Learn more in our BMS protection guide.

This usually happens when the current demand exceeds the battery’s rated limits, triggering protection. See our current ratings guide.

Some heat is normal under load, but excessive heat may indicate high current draw or system inefficiency. See our internal resistance guide.

This may be due to ageing, usage patterns, or storage conditions over time. Learn more in our battery lifespan guide.

Power loss is often caused by voltage drop, poor connections, or incorrect cable sizing within the system. See our voltage drop guide.

Cold temperatures can limit charging and reduce performance due to built-in protection systems. Learn more in our BMS protection guide.

Charging speed depends on charger output, system setup, and battery capacity. See our charging stages guide.

This may be due to charger settings or the battery reaching its voltage limits during charging. Learn more in our charging guide.

System issues are often caused by incorrect setup, wiring, or component compatibility rather than the battery itself. See our system setup guide.

This may be due to wiring issues, insufficient voltage, or protection systems activating. Checking connections and system compatibility is important.

This is often caused by mismatched current requirements or system configuration. See our current ratings guide.
