IntroductionBackgroundUndervoltage Is UnderratedAdding Overcurrent ProtectionConclusionReferencesTo safely utilize lithium-ion or lithium polymer batteries, they must be paired with protection circuitry capable of keeping them within their specified operating range. The most important faults that the batteries must be protected from are overvoltage, overcurrent, and over temperature conditions as these can place the batteries in a daSee more on forum.digikey Last updated: Littelfuse[PDF]
irements should be obtained from the cell manufacturer. Recommendations from device manufacturers are useful in narrowing protection options and benchmarking other pack protection schemes
Mishandling lithium batteries can lead to serious failures like thermal runaway, lithium plating, electrode decomposition, etc. Consequently, such batteries require special care in stressful conditions such as
Protection circuit modules are designed to protect lithium-based chemistries from these two hazards. These modules also may be designed with additional features, such as with short circuit protection,
However, the need for protection circuits to maintain the voltage and current within safe limits is one of the primary limitations of the lithium-ion battery.
Larger packs need a more careful design than a smaller battery, and single cell packs for mobile phones and tablets get away with a voltage and current limit in addition to some intrinsic cell protection.
One of the best ways to maintain optimal safety for your lithium battery is with a solid understanding of circuit protection and its three categories: proper wire sizing, fusing, and breakers.

Over-discharge Protection: Stops the battery from being drained too low, which can cause irreversible damage. Overcurrent Protection: Shuts off the circuit if the current flow becomes
To safely utilize lithium-ion or lithium polymer batteries, they must be paired with protection circuitry capable of keeping them within their specified operating range.
The sections below address common LiFePO4 battery problems and show how to restore stable operation with simple checks and settings for your lithium battery system.
Used as an additional device for short circuit protection. This device limits the current to and from the cells if the pack protect fails. Placed in between cells to monitor temperature. If the cell temperature
