General Information on 36V Lithium Batteries

Battery Management System (BMS)

Most 36V lithium batteries, such as the KS36-105, are equipped with a Battery Management System (BMS). This integrated system enhances battery safety and longevity by providing protection against:

• Overcharge: Prevents damage from charging beyond the battery’s capacity.
• Over-discharge: Protects against excessive discharge that can lead to reduced battery life.
• Short Circuits: Shields the battery from internal and external short circuits.

Charging Recommendations

Using the correct charger for lithium batteries is crucial to maintain battery health and avoid overcharging. Lithium-specific chargers are designed to meet the precise charging requirements of lithium technology, ensuring optimal performance and longevity.

Cycle Life

Lithium Iron Phosphate (LiFePO4) batteries, such as the KS36-105, are known for their extended cycle life. The KS36-105, for instance, offers over 5000 cycles at a depth of discharge (DoD) of 80%-30%. This makes them a cost-effective choice over time due to their durability and long-term performance.

Conclusion

Choosing the right 36V lithium battery involves considering factors such as capacity, voltage, current ratings, and specific features. The KS36-105 offers robust performance with high capacity and advanced features, while options like the Black & Decker battery cater to specific tool applications. Always review the battery’s specifications and ensure you use the appropriate charger to maximize its lifespan and effectiveness.

FAQ
