The Case for Higher Balancing Current BMS in Allied Lithium LiFePO4 Batteries

Article by Mitch Bellman - Engineering Lead, Allied Battery

Allied Lithium LiFePO4 batteries have gained widespread popularity for their impressive energy density, longer cycle life, and enhanced safety features compared to traditional lithium-ion batteries. One crucial component that plays a pivotal role in ensuring the optimal performance, safety, and longevity of Allied Lithium LiFePO4 batteries is the Battery Management System (BMS). In this article, we'll explore the significance of having a higher balancing current BMS for Allied Lithium LiFePO4 batteries and compare the effects of a lower balancing current up to 0.03 amps found in many competitors brands versus 2.0 amps found in allied battery commercial grade products.

Understanding Balancing Current 

Balancing current in a BMS refers to the rate at which the system equalizes the charge among individual cells within an Allied Lithium LiFePO4 battery pack. This process is essential to prevent cell imbalances, which can lead to capacity discrepancies, reduced performance, and even safety hazards. 

Faster Balancing 

A BMS with a higher balancing current, such as 2 amps, can efficiently equalize cell voltages more quickly than a system with a lower balancing current of 0.03 amps. Rapid balancing helps maintain uniform charge levels across all cells, promoting optimal performance and preventing overcharging or over discharging of individual cells. 

Enhanced Safety 

A faster balancing process reduces the risk of overcharging or undercharging allowing the battery to become more balanced under shorter recharge durations thereby enhancing the safety of Allied Lithium battery packs. Safety is paramount, especially in applications where these batteries are utilized in electric vehicles, solar energy storage systems, or other critical applications.

Extended Balancing opportunities 

Not only can Allied LiFePO4 batteries balancer faster but they can also balance anytime the battery is turned on! Other competitors batteries are only able to charge when the battery is under a recharge cycle. This leads to limited balancing times and can cause stack up unbalance where the battery becomes more unbalanced with each cycle never allowing the pack to fully balance during a recharge cycle after heavy use. 

In addition to our superior BMS technology, the Allied Battery iPhone / Android app provides a convenient way to keep an eye on your investment - from live charge status to battery efficiency metrics!

Extended Battery Life 

Allied Lithium LiFePO4 batteries are known for their impressive cycle life, and a BMS with a higher balancing current can further extend this longevity. By ensuring that cells stay balanced over numerous charge and discharge cycles, the overall lifespan of the battery pack is prolonged. 

Optimized Performance 

Balancing currents of 2 amps contribute to maintaining consistent performance across Allied Lithium LiFePO4 battery packs. Uniform cell voltages allow the battery to deliver its full capacity, resulting in optimal efficiency and reliability in various applications. 

Investing in an Allied Lithium LiFePO4 battery pack with a higher balancing current BMS is a strategic choice for those seeking superior performance, safety, and longevity. The benefits of faster balancing, enhanced safety, extended battery life, and optimized performance collectively make a compelling case for the adoption of higher balancing currents in Allied Lithium LiFePO4 commercial batteries.
