What is a Voltage Chart & Why Does It Matter?
A voltage chart is a reference guide that shows the relationship between a battery’s voltage and its state of charge (SOC). For lithium iron phosphate (LiFePO4) batteries like those from Battle Born, this chart is essential because it helps you determine how much energy remains in your battery and whether it needs recharging.
Understanding Battery Voltage
Battery voltage is the electrical potential difference between the positive and negative terminals. In simple terms, it’s a measure of how much “pressure” the battery has to push electricity through a circuit. For Battle Born Batteries (and other LiFePO4 systems), voltage behaves differently than in lead-acid batteries—instead of dropping steadily as the battery discharges, LiFePO4 maintains a relatively flat voltage curve until near depletion.
Why Voltage Matters for LiFePO4 Batteries
- State of Charge (SOC) Indication – The voltage chart allows you to estimate how much charge is left. For example, a resting voltage of 13.3V typically means ~90% SOC, while 12.0V suggests ~20%.
- Battery Health Monitoring – If your battery consistently shows lower voltage than expected for a given SOC, it could indicate aging cells or a balancing issue.
- Preventing Damage – Discharging a LiFePO4 battery below a certain voltage (usually around 10V) can harm its lifespan. The chart helps you avoid over-discharging.
By regularly checking your Battle Born Battery voltage against the chart, you can optimize performance, extend battery life, and avoid unexpected power loss. Want to see the exact voltage ranges? Keep reading—we’ll break down the full Battle Born Battery Voltage Chart next!

Key Features of Battle Born Batteries
1. Lithium Iron Phosphate (LiFePO4) Chemistry
One of the most important features of Battle Born Batteries is that they use Lithium Iron Phosphate (LiFePO4) as their battery chemistry. Compared to other lithium-ion batteries and traditional lead-acid batteries, LiFePO4 is safer, more stable, and longer-lasting. This chemistry is highly resistant to thermal runaway (overheating) and does not catch fire or explode like some older lithium technologies. Additionally, LiFePO4 batteries can be discharged and recharged thousands of times without significant loss of capacity, often lasting 3,000 to 5,000 cycles or more. This makes Battle Born Batteries a reliable, long-term power solution for RVs, boats, and off-grid systems.
2. Built-In Battery Management System (BMS)
Every Battle Born Battery includes a built-in Battery Management System (BMS), which plays a critical role in protecting the battery and ensuring optimal performance. The BMS monitors and manages important functions such as charging, discharging, temperature control, and cell balancing. It prevents overcharging, over-discharging, and short circuits, which can damage the battery or reduce its life span. If conditions become unsafe, the BMS automatically shuts the battery off to protect it. This smart system makes the battery safe and easy to use, even for people with no technical background.
3. Lightweight & Compact Design
Battle Born Batteries are lightweight and compact, making them ideal for mobile and off-grid applications. A typical 100Ah Battle Born battery weighs only around 31 pounds, while a similar-capacity lead-acid battery can weigh 60 to 70 pounds or more. This massive weight reduction is especially valuable in RVs, camper vans, and boats where space and weight matter. The compact size also allows for easier installation and more flexibility when designing your battery system. Despite being lighter, these batteries still provide powerful and consistent energy output.
4. True Deep-Cycle Capability
Unlike lead-acid batteries, which should not be discharged below 50% of their capacity to avoid damage, Battle Born Batteries can be safely discharged down to 100% of their rated capacity. This means you can use the full amount of power stored in the battery without reducing its lifespan or risking failure. For example, a 100Ah Battle Born battery provides nearly 100Ah of usable power, while a 100Ah lead-acid battery only gives you around 50Ah. This deep discharge capability makes Battle Born Batteries more efficient and cost-effective over time.
5. Wide Temperature Tolerance
Battle Born Batteries are designed for fast charging and high energy efficiency. They can accept a higher charge current than lead-acid batteries, which means they charge much faster—especially when using solar panels or high-output chargers. Additionally, lithium batteries like Battle Born have an efficiency rate of around 99%, compared to 80–85% for lead-acid. This means more of the energy you put in actually gets stored and used, reducing waste and making your power system more effective. Fast charging is especially useful when you have limited time to recharge using solar or generator power.

Understanding the Battle Born Battery Voltage Chart
Many assume a dead battery reads 0 volts, but this isn’t true—especially for Battle Born LiFePO4 batteries. Their voltage drops gradually, even at full depletion, protecting the battery from damage. By checking your battery’s voltage, you can estimate its State of Charge (SOC) without specialized equipment. Below, we break down how to interpret these readings.
Resting Voltage vs. State of Charge
When disconnected from chargers or loads, Battle Born Batteries show these key voltage-to-SOC relationships:
| Voltage (V) | State of Charge | Battery Status |
|---|---|---|
| 13.6 | 100% | Fully charged |
| 13.4 | 99% | Near full |
| 13.3 | 90% | Optimal storage level |
| 13.2 | 70% | Moderate charge |
| 13.1 | 40% | Mid-range |
| 13.0 | 30% | Approaching depletion |
| 12.9 | 20% | Low charge |
| 12.8 | 17% | Very low |
| 12.5 | 14% | Critical level – recharge soon |
| 12.0 | 9% | Nearly depleted |
| 10.0 | 0% | Battery protection mode |
Key Takeaways:
- 13.3V = 90% SOC: The battery is nearly full, ideal for long-term storage.
- 12.5V = 14% SOC: Time to recharge to avoid deep discharge.
- 10.0V = 0% SOC: The battery shuts down to prevent cell damage, unlike lead-acid batteries that drop below 10V.
Key Observations About LiFePO4 Voltage Characteristics
- Non-Linear Discharge Curve:
- Unlike lead-acid batteries, LiFePO4 maintains higher voltage longer before dropping sharply near depletion
- The voltage stays above 13V for most of the discharge cycle (90%-30% SOC)
- Protective Cutoff:
- At 10.0V, the battery enters protection mode
- This prevents complete discharge that could damage cells
- The battery isn’t actually “dead” at this point – it’s protecting itself
- Practical Implications:
- For daily use: Try to keep above 12.5V (14% SOC)
- For storage: 13.3V (90%) is ideal for long-term
- For longevity: Avoid regular discharges below 12.8V (17%)
Important Notes About Voltage Readings
- Resting Voltage: For accurate SOC measurement, batteries should rest for 2+ hours after charging/discharging
- Temperature Effects: Voltage readings vary slightly with temperature (about 0.003V/°C per cell)
- Under Load: Expect voltage to sag temporarily when powering devices
- During Charging: Voltage rises to 14.2-14.6V, which is normal
By regularly monitoring your battery’s voltage and understanding this chart, you can:
✓ Maximize battery lifespan
✓ Prevent unexpected power loss
✓ Optimize charging cycles
✓ Maintain reliable performance
For best results, pair voltage readings with a battery monitor for complete SOC tracking. Remember that voltage alone gives a good estimate, but for precise measurements, consider using a shunt-based monitor.
Why Voltage Matters for Battery Health
Battle Born’s voltage curve is flatter than lead-acid batteries, meaning:
- Stable power output until nearly depleted.
- No sudden voltage drops under load.
- 10V cutoff safeguards the battery from over-discharge.
Tip: For accuracy, measure voltage after the battery rests for 1–2 hours (no charging/discharging).
Charging Voltage vs. Resting Voltage
When charging, Battle Born Batteries reach up to 14.6V (higher than resting voltage). This is normal and part of the BMS balancing process. Once charging stops, voltage settles to its true SOC level.
Example:
- A battery charging at 14.6V may drop to 13.3V afterward, indicating ~90% SOC.
Final Tips
- Recharge at 12.5V (14% SOC) to maximize lifespan.
- Never store at 0%—keep batteries at 50%+ SOC if unused.
- Use a voltmeter for reliable readings.

Solve the equation
Understanding the Voltage-Capacity Relationship
The connection between a battery’s voltage and its state of charge (SoC) can be described using a simple mathematical formula. This formula is especially helpful for users who want to estimate battery charge without using a charge monitor. Instead of guessing or relying solely on a chart, you can calculate the approximate voltage based on the SoC, or vice versa.
The formula is:
V = Vmax – (Vmax – Vmin) × SoC
Where:
- V is the voltage at a given state of charge
- Vmax is the battery’s maximum voltage at 100% capacity
- Vmin is the minimum voltage at 0% capacity
- SoC is the state of charge (expressed as a decimal)
This formula works well for understanding the linear relationship between voltage and charge level, especially when the battery is at rest (not charging or discharging).
Using the Formula: A Practical Example
Let’s walk through an example to see how this formula is used in real-life situations. Imagine you have a Battle Born lithium battery and want to calculate the voltage when the battery is at 50% charge. From the earlier voltage chart, we know:
- Vmax = 13.6 volts (voltage at 100% charge)
- Vmin = 10.0 volts (voltage at 0% charge)
- SoC = 50% or 0.5 (converted to decimal)
Now substitute these values into the formula:
V = 13.6 – (13.6 – 10) × 0.5
V = 13.6 – (3.6 × 0.5)
V = 13.6 – 1.8
V = 11.8 volts
This means that at a 50% charge, the battery voltage would read approximately 11.8 volts when it’s not under load or connected to a charger.
Why This Calculation Matters
Being able to calculate voltage based on state of charge (or the reverse) is incredibly useful when monitoring your battery’s health and performance, especially if you’re off-grid or on the road. While voltage can vary slightly based on temperature and usage conditions, this equation offers a reliable estimate that helps prevent over-discharge and keeps your system running efficiently.
