The redodo 24v 100ah lifepo4 battery is a 24-volt, 100 amp-hour lithium iron phosphate pack aimed at DIYers building off-grid solar systems, RV power setups, and small home backup banks. It suits people who want a nominal 2.56 kWh of usable-class storage at a lower-voltage bus that works with common 24V inverters and charge controllers. It is less suited to anyone who needs a 12V-only setup, a pack with published UL certification, or a battery that will be stacked into a large high-voltage bank. This review is based on manufacturer specifications and patterns in owner feedback, not on hands-on testing.
Product Overview
Redodo is a battery brand that sells LiFePO4 packs in a range of sizes, including 12V, 24V, and 48V configurations. The 24V 100Ah model uses lithium iron phosphate chemistry, which is the same family of cells used in most mainstream solar storage today. Compared with lead-acid, LiFePO4 generally offers a flatter discharge curve, a longer cycle life at moderate depth of discharge, and a lower weight for the same capacity. For background on those tradeoffs, see LiFePO4 vs Lead-Acid Batteries for DIY Solar.
The pack is typically marketed for use with 24V solar systems, marine or RV house banks, and off-grid cabins. Its built-in battery management system handles cell balancing and protection functions, which is a practical advantage for DIY installers who do not want to build their own BMS. As with any lithium pack, the internal BMS is what keeps the cells within safe voltage and temperature limits, so the rest of your system must respect its charge and discharge limits.
Key Features & Specifications
The figures below are the ones manufacturers generally specify for this product class. Always check the label and listing on the unit you receive, since revisions occur.
| Specification | Typical Listed Value |
|---|---|
| Nominal voltage | 24V |
| Rated capacity | 100Ah |
| Approximate energy | 2.56 kWh (24V x 100Ah, nominal) |
| Chemistry | Lithium iron phosphate (LiFePO4) |
| Built-in protection | Battery management system (overcharge, over-discharge, overcurrent, short circuit, temperature) |
| Typical configuration | Internal cell arrangement, 8 cells in series for a 24V nominal pack |
| Common use | Off-grid solar, RV, marine, backup power |
Two points deserve attention. First, the 2.56 kWh figure is nominal energy. Usable energy depends on depth of discharge, temperature, and the cutoff set by your inverter. Second, verify the maximum continuous discharge current and the recommended charge current on the specific label. Those numbers decide whether your inverter and charge controller are safely matched to the pack. For sizing the pack to your loads, the guidance in How to Size a Solar Battery Bank: Autonomy, Depth of Discharge and Voltage is a useful reference.
Pros & Cons
Pros
- Lithium iron phosphate chemistry offers a long cycle life at moderate depth of discharge compared with lead-acid.
- The 24V nominal voltage fits many mid-size off-grid inverters and reduces current for a given power level compared with 12V.
- Built-in BMS handles core protections, which simplifies installation for DIYers.
- Weight is substantially lower than a comparable lead-acid bank, which helps with mounting in RVs, boats, and small enclosures.
- Owners often report a flat discharge curve, meaning voltage stays relatively stable through most of the discharge.
Cons
- Nominal energy of roughly 2.56 kWh is modest for whole-home backup, so larger loads will need multiple packs.
- Cold-weather charging restrictions are common in LiFePO4 packs; charging below freezing typically requires heating or a low-temperature cutoff.
- Build quality and BMS behavior can vary between production batches, and some owners report needing to check balance on arrival.
- Documentation, warranty terms, and support responsiveness are areas where buyers should read the listing carefully before purchase.
- Parallel expansion requires matched packs and careful wiring, which is not beginner-friendly.
Performance Analysis
Performance for a 24V 100Ah LiFePO4 pack is driven by three things: how much of the nominal capacity you can actually use, how the pack behaves under load and temperature, and how well the BMS protects it over time.
Usable Capacity and Depth of Discharge
LiFePO4 is commonly rated for deep cycling, with many manufacturers listing 80 to 100 percent depth of discharge as usable. If you plan around 80 percent, the 2.56 kWh nominal figure translates to roughly 2.05 kWh of usable energy. A daily load of 1.5 kWh would therefore take about 73 percent of usable capacity per day, which leaves little margin. A more conservative design would size for 50 to 60 percent daily use with a solar array able to recharge the pack within a day.
Load and Discharge Behavior
Owner reports on forums and retailer reviews often describe stable 24V output under moderate loads such as refrigerators, lights, and small inverter loads. Watch the continuous discharge rating. A pack rated for, say, 50 to 100 amps continuous can support a 2000 W inverter at 24V (roughly 83 amps DC before efficiency losses), but a 3000 W load would exceed the safe continuous rating of many packs in this size class. Always check the listed continuous and peak values.
Temperature Effects
Charging LiFePO4 below freezing risks lithium plating and permanent damage. Most packs in this class include low-temperature charge protection, but that protection usually just stops charging rather than heating the cells. If you live in a cold climate, plan for an insulated enclosure or a heater, and consult a professional if you are unsure about your site conditions.
Longevity
Cycle life is the main reason to choose LiFePO4. Manufacturers typically list several thousand cycles at a stated depth of discharge. Real-world life depends heavily on how often the pack is deeply discharged, how hot it runs, and whether it is kept near full charge for long periods. Moderate daily cycling at 50 to 70 percent depth generally extends life more than frequent full-depth cycling.
Who Should Buy This Product?
This pack fits a specific set of builders. It is a good match if you are building a 24V off-grid or RV system with modest daily consumption, want to avoid assembling your own BMS, and have a charge controller and inverter rated for 24V LiFePO4 charging profiles. It is also a reasonable choice for a backup bank that powers essential loads during outages.
You should skip it if your system is 12V or 48V only, if you need a single pack to run a whole house, if you live where winter temperatures routinely fall below freezing without a heated enclosure, or if you require a specific certification that the listing does not document. For essential-load backup planning, Solar Battery Backup Planning: Essential Loads and Safe Connections walks through how to match a pack to critical circuits.
Buying Guide
Before buying any 24V LiFePO4 pack, check five things.
- Voltage compatibility. Confirm your inverter and charge controller support a 24V LiFePO4 charge profile, with the correct absorption and float voltages set for lithium rather than lead-acid.
- Continuous and peak current. Divide your maximum inverter output by 24V and add a safety margin. Compare that figure with the pack’s listed continuous rating.
- Protection and fusing. Install a properly rated fuse or breaker close to the positive terminal. Review guidance in DIY Solar Safety: Wiring, Fuses and Batteries before wiring.
- Temperature plan. Decide how the pack will be kept above freezing during charging. Read Solar Battery Safety: Charging, Temperature, Enclosures and Storage.
- Measurement tools. A multimeter and a battery monitor help verify voltage and state of charge after installation. See Solar Measurement Tools: Multimeters, Clamp Meters and Battery Monitors.
Sizing is where many builds go wrong. Use DIY Solar Sizing Calculations: Panels, Battery Banks and Inverters to work out daily watt-hours, then divide by usable energy per pack.
Well-Known Alternatives

FAQ
Is the redodo 24v 100ah lifepo4 battery suitable for a 24V off-grid system?
Yes, a 24V nominal pack is designed for 24V solar and inverter systems. Confirm that your charge controller and inverter use a lithium charge profile and that their voltage limits match the pack’s specifications.
How much usable energy does a 24V 100Ah LiFePO4 pack provide?
The nominal figure is about 2.56 kWh. With 80 percent usable depth of discharge, that drops to roughly 2.05 kWh. Actual usable energy depends on temperature, discharge rate, and your inverter’s low-voltage cutoff.
Can I charge it in freezing temperatures?
Generally no. Charging LiFePO4 below freezing can damage cells. Keep the pack in a heated or insulated enclosure, and consult a professional if your site is exposed to cold.
Can I connect multiple packs in parallel?
Parallel connection is common for expanding capacity, but packs should be matched in age, state of charge, and BMS behavior. Follow the manufacturer’s maximum parallel count and use proper busbars and fusing.
How long should it last?
Manufacturers typically list several thousand cycles at a stated depth of discharge. Lifespan depends on depth of discharge, temperature, and charging habits. Moderate daily cycling generally extends life.
Does it need a separate BMS?
Not if the built-in BMS is functioning as specified. However, you still need overcurrent protection (fuse or breaker) in your wiring, and your charge controller and inverter should respect the pack’s voltage and current limits.
Is it a good choice for an RV?
It can be, provided your RV’s charging system supports 24V lithium profiles and the pack is mounted securely with adequate ventilation and temperature protection. Check the continuous discharge rating against your appliances.
Final Verdict
The redodo 24v 100ah lifepo4 battery is a sensible option for DIY builders who want 24V lithium storage at moderate energy levels, with a built-in BMS and the cycle-life advantages of LiFePO4. Its strengths are the 24V format, low weight, and straightforward integration. Its limits are the modest nominal energy, temperature constraints for charging, and the need to verify documentation and current ratings before committing. If your load profile fits its capacity and your site stays above freezing, it is worth considering. Review the specifications on the listing carefully and confirm compatibility with your controller and inverter. View on Amazon
