Redodo vs Power Queen 100Ah LiFePO4: Charger, BMS and RV Fit
Do not choose 100Ah batteries by capacity alone. Check BMS discharge current, supported charger voltage, cold-weather charge protection and physical mounting.
Do not choose 100Ah batteries by capacity alone. Check BMS discharge current, supported charger voltage, cold-weather charge protection and physical mounting.
What matters
- Compare nominal 12.8V capacity, continuous BMS current and approved charge-current range from each specific product sheet.
- Cold charge cutoff, optional heating and charging temperatures must be verified per SKU, not inferred from a brand's other batteries.
- Check terminal orientation, battery box dimensions, fuse requirements and charger compatibility before attempting a replacement.
- Compare delivered price, warranty exclusions and capacity at expected temperatures, without assuming cycle-life claims equal guaranteed service years.
Both brands can be candidates only after the exact models satisfy the electrical system's documented constraints.
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.
