Renogy vs Power Queen vs Redodo 100Ah LiFePO4: Which 12V Battery Fits?
Compare Renogy Core Mini, Power Queen Group 24 Smart and Redodo Group 31 Bluetooth 12V 100Ah LiFePO4 batteries by size, BMS, low-temperature protection, Bluetooth, warranty and RV/solar fit.
These three batteries are unusually comparable electrically: each is a 12.8V 100Ah LiFePO4 battery with roughly 1,280Wh of nominal energy and a 100A continuous BMS. The meaningful differences are physical format, monitoring features, cold-charge protection, cycle-test claims and how much space you have in the installation.
Electrically, these models are close: 12.8V, 100Ah, about 1,280Wh and 100A continuous BMS ratings. Renogy Core Mini wins space efficiency; Power Queen Group 24 Smart adds Bluetooth and low-temperature protection in a shorter Group 24 case; Redodo Group 31 Bluetooth offers similar smart/cold protection in a conventional longer Group 31 footprint. Pick from fit, monitoring and charging environment—not from the logo alone.

Renogy Core Mini 12V 100Ah
The compact option in this comparison. Verify current Core Mini pricing, low-temperature protection and fit before buying.
Power Queen Group 24 Smart 100Ah
Bluetooth monitoring and low-temperature charging protection in a Group 24-size 1,280Wh battery.
Redodo Group 31 Bluetooth 100Ah
A 1,280Wh Group 31-format option with Bluetooth monitoring, 100A BMS and low-temperature charge cutoff.
What matters
- Renogy Core Mini is the most compact of the three at about 9.02 × 5.43 × 8.39 inches and 21.8 lb, while still listing a 100A maximum continuous charge/discharge current and low-temperature charging protection.
- Power Queen Group 24 Smart adds Bluetooth 5.0 monitoring and low-temperature charge protection in a Group 24-size case of about 10.24 × 6.61 × 8.27 inches at 22.16 lb.
- Redodo Group 31 Bluetooth also adds app monitoring and low-temperature charge cutoff, but uses a longer Group 31-style case at about 13 × 6.77 × 8.5 inches and 22.84 lb.
- All three are 1,280Wh-class batteries with 100A continuous discharge limits, so none should be treated as a higher-power battery simply because its enclosure or app features differ.
- Cycle-life numbers are not directly interchangeable because the manufacturers publish them under different depth-of-discharge and test assumptions. Use warranty terms, BMS limits and fit as primary filters before comparing headline cycle counts.
Decision factors that change the answer
Physical fit
Renogy Core Mini is about 9.02 × 5.43 × 8.39 in. Power Queen Group 24 Smart is about 10.24 × 6.61 × 8.27 in. Redodo Group 31 Bluetooth is about 13 × 6.77 × 8.5 in. In an RV or boat battery bay, those dimensions can matter more than a small price difference.
Monitoring
Power Queen Group 24 Smart and Redodo Group 31 Bluetooth both publish Bluetooth app monitoring. Renogy’s standard Core Mini page emphasizes compact size and protection rather than Bluetooth, so buyers who require app monitoring should verify the exact Renogy variant instead of assuming it is included.
Cold charging
All three comparison models publish low-temperature charging protection/cutoff. That protects cells from charging below the specified threshold, but it is not the same as a self-heating battery that can warm itself and continue charging in colder conditions.
Continuous output
Each comparison model lists a 100A continuous discharge class. At 12.8V that is roughly 1,280W battery-side before inverter losses, so none becomes a high-power 12V battery merely because its enclosure, Bluetooth or cycle claim differs.
Cycle-life claims
Renogy publishes 5,000 cycles at 80% depth of discharge / 80% end-of-life for Core Mini. Power Queen and Redodo publish 4,000-cycle claims at 100% depth of discharge for the compared smart models. Because test conditions differ, do not rank them from the headline cycle number alone.
Warranty
All three publish five-year coverage, but Renogy describes its material/workmanship warranty as prorated. Read the current full terms before treating “5 years” as identical protection.
How to size it
- Measure the battery compartment before comparing price. The Renogy footprint is materially shorter than the Redodo Group 31 case.
- Calculate daily watt-hours and desired autonomy. A 100Ah label does not tell you whether one battery is enough for your load.
- Check the inverter or DC load against the 100A continuous BMS limit. At 12.8V, 100A corresponds to about 1,280W of battery-side power before system losses.
- Verify the charger, converter, DC-DC charger and solar controller are compatible with LiFePO4 charging voltage and your desired recharge time.
- If the installation can see freezing temperatures, distinguish low-temperature charge cutoff from self-heating. A cutoff protects the battery; it does not warm it so charging can continue below freezing.
Suppose an RV uses 850Wh between charging opportunities. Any of these 1,280Wh batteries is in the right nominal capacity class, but the decision can still change: a tight compartment favors the Renogy Core Mini; a Group 24 tray plus app monitoring favors Power Queen Smart; an existing Group 31 compartment plus Bluetooth monitoring can favor the Redodo Group 31 model. If the inverter requires substantially more than 100A from one battery, none of the three is solved by choosing on brand alone.
Worked example
An RV owner needs about 900Wh overnight, uses a 1,000W inverter and has a narrow battery compartment. Capacity is adequate across all three 1,280Wh models. The inverter also fits within the 100A-class BMS in normal operation. At that point, the physical tray becomes decisive: the compact Renogy can fit where a Group 31 case may not. If app-based SOC monitoring matters and a Group 24 tray fits, Power Queen becomes more attractive. If the RV already has a Group 31 bay and the owner wants Bluetooth, Redodo can be the cleaner fit.
Common buying mistakes
- Choosing from Bluetooth features before confirming physical fit and charging compatibility.
- Treating 4,000-cycle and 5,000-cycle manufacturer claims as directly comparable when the published depth-of-discharge conditions differ.
- Assuming low-temperature protection means the battery is self-heating.
- Sizing an inverter from battery watt-hours while ignoring the 100A continuous BMS limit.
- Mixing batteries of different brands, ages or specifications in one bank without explicit manufacturer support.
When this approach fits best
- Renogy Core Mini: constrained RV, van, boat or cabinet installations where footprint is the first constraint.
- Power Queen Group 24 Smart: buyers who want Bluetooth and low-temperature charging protection in a relatively compact Group 24 form.
- Redodo Group 31 Bluetooth: existing Group 31 installations where Bluetooth and cold-charge cutoff matter.
- Any of the three: 12V systems whose measured load and charging plan fit a 1,280Wh / 100A-class battery.
When to choose differently
- Choose a self-heating model if the battery must continue accepting charge below freezing rather than simply blocking unsafe charging.
- Choose a higher-current BMS model or higher-voltage system if your inverter demand exceeds what a single 100A-class 12V battery can support.
- Choose a different capacity if your measured daily watt-hours require materially more or less than 1,280Wh nominal storage.
- Do not parallel mixed brands or models simply because the nominal voltage and amp-hours match.
Choose by system fit rather than brand prestige. Renogy Core Mini is compelling when compact dimensions matter; Power Queen Group 24 Smart combines a smaller BCI-style case with Bluetooth and cold-charge cutoff; Redodo Group 31 Bluetooth fits buyers who want the same 100Ah/100A electrical class in a conventional longer Group 31 footprint with app monitoring. All three are approved commercial partners, but the comparison criteria are based on current manufacturer specifications rather than affiliate payout.

Use the numbers before choosing a model
Start with your load list. The battery needs enough watt-hours for the desired runtime and enough continuous/surge watts to operate the appliances at the same time. Then check whether your recharge method can replace the energy you expect to consume.
For outage planning, we recommend keeping reserve capacity instead of designing a system that reaches 0% at the end of the forecasted outage.
