1.2 BMS – Multiple Protection Structures

BMS is indispensable for ensuring the safe operation of both the Group24 and Smart Group24 batteries.

The BMS is a comprehensive system designed to monitor, evaluate, balance, and safeguard the battery from potential hazards. In the case of Group24 batteries, they are equipped with a built-in 100A BMS featuring an extensive protection system. This system safeguards the battery against over-voltage, over-current, over-heating, over-discharge, and over-charging. Additionally, it balances the battery pack during the charging process.

Continuous charging or discharging of batteries without proper balancing can lead to capacity degradation over time. Hence, ensuring all batteries are balanced is a critical feature to prevent overcharging and maintain optimal performance.

2.Differences Between Power Queen Group 24 And Group 24 Smart

Both Group24 and Smart Group24 lithium batteries have the unique advantages of lithium batteries in their external design and built-in structure. But there are some differences between these 2 batteries.

2.1 Weight & Surge Discharge Current

The weight of the two Group 24 batteries is slightly different: the Smart Group 24 version weighs 21.83 pounds, while the Premium Group 24 version weighs 21 pounds.

Despite the weight difference, the SMART version discharges at up to 500 amps per second, while the Premium Group 24 discharges at 400 amps per second. This means the Smart Group24 lithium battery has a higher instantaneous load capacity. This enhanced capacity provides the power necessary for fast and efficient fishing, ensuring a smoother boating experience.

2.2 Low Temperature Cut-off Protection

Cold weather significantly impacts lithium battery life and performance. It’s crucial to adhere to the recommended lithium battery temperature ranges:

  • Charging: 0℃ to 50℃ (32°F – 122°F)
  • Discharge: -20℃ to 60℃ (-4°F – 140°F)
  • Storage: -10℃ to 50℃ (14°F – 122°F)

Charging lithium batteries below freezing hampers the absorption of lithium ions by the anode, resulting in lost capacity and diminished performance. Here’s how cold temperatures affect battery operation:

  • Reduced Capacity:Cold temperatures slow down chemical reactions, reducing the battery’s capacity. This translates to decreased power and shorter run times.
  • Increased Internal Resistance:Higher resistance impedes current flow, lowering battery performance.
  • Potential Hazards:Extreme cold can freeze the electrolyte, causing excessive plating that may puncture the diaphragm, leading to short circuits, capacity loss, leakage, or even explosions.

To ensure longevity, performance, and safety, it’s crucial to keep the battery within the recommended temperature range. This ensures optimal operation and minimizes potential hazards.

Incorporating a protectionist mechanism helps maintain battery performance, capacity, and lifespan while mitigating the risks associated with low temperatures.

The Smart Group24 lithium battery offers a significant advantage over the Premium Group24 due to its 100A BMS featuring low-temperature cut-off protection. This innovative feature actively monitors individual cell temperatures, permitting charging only when temperatures exceed 32°F (0°C). Charging halts automatically if temperatures drop below -4°F (-20°C), resuming once temperatures surpass 5°F (41°C).

For users spending extended periods in cold climates or during winter, the Smart Goup24’s cryogenic cut-off protection offers an added layer of energy security.

2.3 Convenient And Comprehensive Bluetooth Monitoring

One standout feature of the smart Group24 is its Bluetooth-enabled wireless connectivity, eliminating the need for cumbersome wiring through walls. Unlike traditional wired battery monitors that require additional wiring and expenses for extended distances, our Smart Group24 battery’s integrated Bluetooth functionality offers seamless monitoring without any extra costs.

4.FAQs About Power Queen GROUP24 VS SMART GROUP24

1.Can I use this battery as a car starter battery or golf cart battery?

NO. Power Queen does not currently offer starter batteries or golf cart batteries.

2.Can I connect these two batteries in series?

No. The cells and BMS of these two batteries are different, so we don’t recommend connecting them in series, which will damage the internal structure of the batteries and reduce their life span.

3.How to charge the battery?

We don’t recommend using a lead acid charger for a long time, as it will affect the performance and life of the lithium iron phosphate battery. Suggest reading: Can I Charge LiFePO4 Battery with a Lead Acid Battery Charger?

There are three reliable charging methods: solar panel, Li-FePO4 charger and generator.

4.What do I need to be aware of when I receive my shipment?

When you receive your shipment, it’s important to note that the battery’s State of Charge (SOC) may be low due to shipping and storage. For optimal performance, we advise promptly charging the battery to prevent complete discharge.

If you anticipate not using the battery for an extended period, it’s best to charge it to 30%-50% SOC and conduct maintenance every three months. This practice ensures battery performance and stability are maintained. Suggest reading: How to Properly Store LiFePO4 Lithium Batteries


Both the 12V 100Ah Premium Group24 and the 12V 100Ah Group 24 Smart offer comparable performance to the lithium battery. However, the key distinction lies in the Smart Group24’s additional features, including low-temperature cut-off protection and Bluetooth functionality.

If you reside in colder climates or frequently encounter low temperatures, or if you value real-time battery monitoring, the Smart Group24 is the ideal choice.

On the other hand, if you’re working within a budget or prefer not to rely on smartphone connectivity, the Group24 remains a solid option.You’ll need to pair it with an additional wired battery monitor, which makes it easy to monitor the health of your battery, but you’ll need to be close to the system to see it.
