FAQ's

What is the maximum charging current for a 12V 100Ah LiFePO4 battery?

Our 12V 100Ah LiFePO4 batteries have a maximum charging current of 100A. However, we typically recommend charging them at 0.2C (20A) for optimal balance of speed, safety, and longevity.

How many watt hours in a 100Ah 12V battery​?

Watt-Hours = Amp-Hours x Battery Voltage
100Ah x 12.8V = 1280Wh

Can a 12V 100Ah battery be used in extreme temperatures?

The recommended operating temperatures for our 12V 100Ah lithium battery are:

  • Charging: 0°C – 65°C
  • Discharging: -20°C – 70°C
  • Storage: 0°C – 60°C

The built-in Battery Management System (BMS) provides high- and low-temperature protection, ensuring safe operation. For example:

  • Low-Temperature Protection: Automatically halts charging if the temperature drops below -20°C to prevent damage.
  • High-Temperature Protection: Stops charging/discharging if temperatures exceed 65°C (charging) or 70°C (discharging).

Key Notes:

  • Performance in Extreme Conditions: While the battery can operate in these ranges, optimal performance is achieved within 20°C – 25°C.
  • Avoid Prolonged Exposure: Extended use outside the recommended ranges may reduce lifespan or efficiency.
  • Storage: Keep the battery in a dry, temperature-controlled environment when not in use.

Safety First!
The BMS ensures safe usage, but always monitor battery conditions in extreme environments.

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

Battery runtime is influenced by multiple factors, including battery capacity, connected load, and the battery’s condition. For example, a new battery performs better than a used one, as its capacity slightly decreases with repeated charge cycles. However, you can estimate runtime using a simple formula based on power consumption and battery capacity:

Runtime (hours) = Battery Capacity (Wh) / Total Device Power Consumption (W)

Example:
If you have a 12V 100Ah battery and connect a 50W lamp and a 50W speaker, the runtime will be:
1280Wh / (50W + 50W) = 12.8 hours

This straightforward formula helps estimate runtime under different loads. Always consider real-world factors like temperature and battery aging for more accurate predictions.

What size solar panel to charge 12V 100Ah battery?​

To charge a 12V 100Ah battery from 100% depth of drain in 4.5 peak sun hours, approximately ≥400 watts of solar panels and an MPPT charge controller are required.

Is it better to have a 2 100Ah or 1 200Ah battery?

Two 12V 100Ah batteries in parallel and a single 12V 200Ah battery provide the same total capacity (200Ah). However, using a single 200Ah battery offers key advantages:

  • Consistency & Stability
    A single battery ensures uniform cell aging, voltage balance, and consistent performance.
    Parallel configurations risk imbalances due to differences in internal resistance or slight capacity variations between batteries.
  • Simpler Setup
    Fewer wiring connections reduce complexity and potential failure points.
    Saves space and minimizes installation effort.
  • Compact Design
    A single 200Ah battery occupies less physical space than two 100Ah batteries.

When to Choose Two 100Ah Batteries:
Redundancy: If one battery fails, the other can still provide partial power.
Scalability: Easier to expand capacity incrementally (e.g., adding more batteries later).

Final Recommendation:
For most applications (e.g., solar storage, RVs, backup power), a single 200Ah battery is preferred for simplicity, reliability, and space efficiency. Use parallel setups only if redundancy or scalability is a critical priority.

Can I connect this 12V 100Ah lithium battery with a Mini battery?

Not recommended. WattCycle requires four rules for safely connecting batteries in series or parallel:

  • Same brand
  • Same voltage
  • Same current (capacity)
  • Purchased within 6 months

Why Mixing Different Batteries Is Risky:

  • Imbalanced Performance: The 12V 100Ah battery and mini battery likely differ in capacity, internal resistance, or age, leading to uneven charging/discharging.
  • Reduced Efficiency: One battery may drain faster, forcing the other to overwork.
  • Safety Risks: Mismatched batteries can overheat, degrade prematurely, or even fail.

Recommendation:

  • Use identical batteries (same brand, voltage, capacity, and age) for safe and stable operation.
  • If you need more capacity or voltage, stick to one battery type (e.g., If you need a 24V 100Ah battery system, then it is recommended to purchase a 24V 100Ah battery instead of 2 12V 100Ah batteries).
What is the difference between a 12V 100Ah battery and a Mini battery?

The primary difference lies in their physical size:
12V 100Ah battery dimensions: L260 x W168 x H209mm
Mini battery dimensions: L229 x W138 x H208mm

How long do 4 Parallel 12V 100Ah lithium batteries last?

By connecting 4 parallel 12V 100Ah lithium batteries, you significantly increase your system’s total capacity, extending runtime. This configuration creates a 12V 400Ah battery system, delivering up to 5.12kWh of energy.

Runtime Calculation:
Runtime (hours) = Total Battery Capacity (Wh) / Total Device Power Consumption (W)

Example:
If you connect 4 parallel 12V 100Ah lithium batteries to a 50W lamp and a 50W speaker:
5.12kWh (5120Wh) / (50W + 50W) = 51.2 hours

USER MANUAL

Tested, Reviewed, and Approved by YouTubers

The build quality is nice. Everything is torqued and glued. Blance leads are protected and these cells look new. This might be my new favorite Budget battery! This is objectively better than other brand and it costs less money. It looks so cheap on the outside but on the inside it is so nice.

YouTuber @DIY Solar Power with Will Prowse

Based on the results of this test, I can conclude that the WattCycle 100Ah batteries indeed have at least 100Ah in them. In fact, they have more than that. Plus, they have a little bit of extra on top and for that I give them a thumbs up! 👍

YouTuber @Solar Power Edge

This battery for load handling gets five stars! It handled the load to full power pull very well, no problems at all. With that capacity, it gets five stars! It gives you more than what you paid for. Very, very energy-dense unit right here.
