Redway Power 12V 100Ah Rechargeable LiFePO4 Battery Review

Redway Power’s 12V 100Ah rechargeable LiFePO4 battery is a hot selling model designed to replace lead-acid batteries with a capacity of around 200Ah. This advanced battery uses Lithium Iron Phosphate (LiFePO4) chemistry to provide reliable, safe power in all conditions while reducing weight significantly. It is suitable for a wide range of applications including solar, campers, caravans, golf carts, electric wheelchairs as well as sailing and boating.

The battery has a depth of discharge of about 90% and has a similar capacity to a 200Ah capacity lead/gel/AGM battery which typically has a depth of discharge of about 50%. Plus, it weighs just 11.9kg, compared to about 60kg for a 200Ah lead-acid battery.

What are the advantages of lithium iron phosphate?

LiFePO4 batteries are a popular choice for those looking for a high-performance, long-lasting battery. But there are a few things to consider before switching to this type of battery. Here are some advantages of LiFePO4 batteries:

1. Longer battery life than other types of batteries – up to 10 years or more.

2. Higher energy density means more power in a smaller package.

3. Safer than other types of batteries, there is almost no risk of fire or explosion.

4. Can be charged and discharged more times than other types of batteries without loss of capacity.

Which is better, lithium iron phosphate battery or lithium ion battery?

When comparing LiFePO4 and Li-ion batteries, consider your needs. LiFePO4 offers durability and deep discharge resistance but is pricier. Li-ion batteries provide higher energy density and lower cost but degrade over time. Choose LiFePO4 for longevity and safety, Li-ion for affordability and energy density.

LiFePO4 batteries are prized for their long life and safety. They also tolerate deep discharge better than other battery types, which means they can be used in a wider range of applications. However, they are not without drawbacks. LiFePO4 batteries tend to be more expensive than other battery types, and they do not have the same high energy density as Li-ion batteries.

Lithium-ion batteries are the most popular type of battery on the market today. They offer high energy density and are relatively inexpensive. However, lithium-ion batteries can be dangerous if used incorrectly. They also degrade over time, losing capacity and eventually requiring replacement.

So, which is better? It depends on your needs. If you need a long-lasting battery with high deep discharge resistance, then LiFePO4 is a good choice. If you need a battery that is cheaper and has a higher energy density, Lithium-ion batteries are the better choice.

12V 100Ah LiFePO4 Battery FAQ

How long will a 12V 100Ah LiFePO4 battery last?

How long will a 12V 100Ah LiFePO4 battery last?

A 12V 100Ah LiFePO4 battery lasts differently depending on the power consumption of the device it powers. Assuming 85% system efficiency, here are some estimated run times for different power usage:

– 100W load: up to 10 hours
– 50W load: up to 20 hours
– 70W load: up to 14 hours
– 200W load: up to 5 hours
– 500W load: up to 2 hours
– 1000W load: up to 1 hour
– 3000W load: up to 20 minutes

Note that these estimates are based on continuous usage. If the unit is running intermittently, the run time will be longer.

How long does it take to charge a 100Ah 12V lithium battery?

The charging time for a 100Ah 12V lithium battery varies based on charger and rate. Typically, using a 30 amp charger, it takes 3 to 4 hours to fully charge. However, times may differ; consult the manufacturer’s recommendations for precise charging instructions.

How much voltage should I charge my 12V LiFePO4 battery?

The recommended charging voltage for a 12V LiFePO4 battery typically ranges between 14.2V and 14.6V, approximately 3.55V to 3.65V per cell. Always consult the battery manual for precise parameters to ensure safe and proper charging.

How to charge a 100Ah LiFePO4 battery?

Charging a LiFePO4 battery requires attention to detail for safety and efficiency. Use a charger compatible with 14V to 14.6V output. Connect terminals securely, set voltage and current, monitor progress, charge to 90-95% capacity, and disconnect safely. Refer to manufacturer guidelines for specifics.

Here’s a simplified guide:

  1. Choose the right charger: Ensure compatibility with a 14V to 14.6V output.
  2. Connect the charger: Securely attach the positive and negative terminals.
  3. Set charging parameters: Adjust voltage and current settings for LiFePO4 charging.
  4. Begin charging: Once set up, start the process.
  5. Monitor progress: Keep an eye on battery temperature and charging speed.
  6. Charge to capacity: Complete until the battery reaches 90-95% capacity.
  7. Disconnect safely: Once fully charged, disconnect the charger to prevent overcharging.

Always refer to the manufacturer’s guidelines for specific instructions.

How to maintain LiFePO4 battery?

Maintaining LiFePO4 batteries ensures longevity and performance. Charge with lithium-specific chargers, aim for rates between C/4 and C/2, monitor levels regularly, store at 50% charge in cool areas, conduct full cycles every 6-12 months, and inspect for damage. Following these guidelines maximizes safety and battery efficiency.

Here’s how:

  1. Charge correctly: Utilize lithium-specific chargers to complete full cycles.
  2. Choose the right rate: Opt for charging rates between C/4 and C/2.
  3. Monitor health: Regularly assess battery levels and runtime to gauge health.
  4. Store appropriately: Maintain batteries at 50% state of charge in cool, dry spaces.
  5. Perform maintenance cycles: Conduct full cycles every 6-12 months for stored batteries.
  6. Inspect for damage: Check terminals and casing regularly, avoiding damaged batteries.

Adhering to these guidelines maximizes safety and performance of LiFePO4 batteries.

What is the charge cycle of a LiFePO4 battery?

LiFePO4 battery charging involves two phases: Constant current (CC) charging, maintaining a steady current for efficient charging, followed by constant voltage (CV) charging, where voltage stabilizes while current decreases to prevent overcharging. Specific parameters vary; consult the battery manufacturer‘s recommendations. Good quality LiFePO4 batteries can last over 5000 cycles at 80% Depth of Discharge.

  1. Constant current (CC) charging: Initially, the battery is charged at a consistent current, typically between 0.3C and 1.0C. This phase ensures rapid and efficient charging, with the duration influenced by the battery’s capacity and charging current.
  2. Constant voltage (CV) charging: Once the battery voltage reaches a set threshold, often around 3.6V per cell, the charging mode shifts to constant voltage. Here, the voltage remains steady while the charging current gradually decreases. This phase guarantees complete charging and prevents overcharging.

Keep in mind that specific charge cycles and parameters may vary based on the battery manufacturer’s recommendations and the battery model. Always consult the battery’s instructions or datasheet for the recommended charging profile.
