LiFePO4 vs Lead Acid: a comprehensive comparison of advantages
| Feature | Hongyitai 12V 150Ah LiFePO4 | Traditional Lead-Acid (Typical) | Key LiFePO4 Advantage |
|---|---|---|---|
| Cycle Life | 6,000+ cycles (@80% DoD) | 300 – 500 cycles | ~10x Longer Lifespan (10+ years vs. 2-3 years) |
| Usable Capacity (DoD) | ~100% Recommended | ~50% Recommended | Nearly Double the Runtime (150Ah LiFePO4 ≈ 300Ah Lead-Acid usable energy) |
| Weight | [Your 150Ah LiFePO4 Weight] kg / lbs | >45 kg / >100 lbs (for similar usable capacity) | Over 50% Lighter – Easier handling, better performance |
| Energy Density | Higher | Lower | More power in less space/weight |
| Charging Speed | ~2-3 hours (at 0.5C rate) | 8+ hours | Significantly Faster Recharge |
| Charging Efficiency | >95% | ~80-85% | Less wasted energy, better solar utilization |
| Maintenance | Zero Maintenance Required | Requires regular checks, watering, cleaning | Hassle-Free Operation |
| Safety | Stable chemistry, Built-in Smart BMS (multiple protections), No acid/gas | Risk of acid leaks, hydrogen gassing (explosion risk), no integrated BMS | Superior Safety & Peace of Mind |
| Voltage Stability | Stable ~12.8V during discharge | Voltage drops significantly | Consistent power for appliances |
| Installation | Mount in any orientation | Upright mounting only | More Flexible Installation Options |
12V 150Ah lithium battery application
The eco-worthy 12v 150ah lithium battery sounds very advanced technology. It is particularly suitable for those common applications that have high requirements on power endurance, weight, service life and reliability, such as: golf carts, campers, boats, solar off-grid systems, electric wheelchairs, etc.
How to replace 12V 150Ah lead acid battery
It sounds great, but is it hard to replace your old lead-acid battery with a deep cycle battery? Do I need to make any changes? You can find the answers here.
- The size matches. Physical installation is usually a direct drop-in. Take out the old heavy lead-acid battery and put this much lighter new lithium battery in, and the size and space are usually no problem. The terminal is also a standard M8 interface, and your existing cables can be directly connected.
- Most charging settings designed for lead-acid batteries cannot be directly used for lithium iron phosphate batteries because lithium iron phosphate batteries require CC/CV charging and the charging voltage is 14.2V ~ 14.6V.
- If solar charging is required, a lithium battery type device is required in the controller (MPPT or PWM).
- Once the charging system is figured out, wiring is simple. Make sure the positive terminal is connected to the positive terminal (usually the red wire) and the negative terminal is connected to the negative terminal (usually the black wire). Make sure the connection is secure and tighten the terminal screws.
- If you want to combine series and parallel to increase voltage and capacity, we support it. Up to 16 series and 4 parallel are supported. Please contact us for details.
Why choose Hongyitai 12V 150Ah lithium battery
- We are a Chinese lithium battery factory. Hongyitai focuses on lithium iron phosphate (LiFePO4) technology, especially as a solution to replace lead-acid batteries. We are more fully prepared and experienced in dealing with various problems you may encounter during the upgrade process from lead-acid.

- We provide professional pre-sales consultation and after-sales services. We not only sell batteries, but also provide a complete set of solutions and long-term service guarantees.
- We provide a 5-year product warranty, which is not only our confidence in product quality, but also a real guarantee for you.
FAQs for 12v 150ah lithium battery
The discharging time of a 12V 150Ah battery depends on the load power. If the power consumption of the refrigerator is 75W (about 6.25A), this battery can last about 24 hours.
For a 150Ah battery: 150Ah * 12V = 1800Wh.
Assume that you want to fully charge the battery within 5 hours. The required solar panel power: = 1800Wh / 5H = 360W.
Considering the inverter efficiency factor is 90%, 360W / 0.9 = 400W.
If you choose a 100W solar panel: then the number of solar panels required = 400W / 100W = 4.
If a 20A charger is used, the full charge time = 150Ah / 20A = 7.5H.
