These battery packs have gained widespread popularity due to their lightweight nature, high energy density, long cycle life, and low self-discharge rates. They serve as reliable power sources for a wide range of devices and systems, from portable electronics to recreational vehicles, making them an essential component in today's technology-driven world.
12V lithium battery pack vs. lead acid battery pack - Which is better?
When comparing 12V lithium-ion battery pack to traditional lead acid battery packs, it becomes evident that lithium-ion technology offers several distinct advantages.
● Lithium-ion battery packs
Longer cycle life: Compared to lead-acid batteries, lithium-ion packs have a longer cycle life. The fact that they can withstand thousands of charge-discharge cycles means that they will last longer in use.
Low self-discharge rate: Lithium-ion batteries do not lose their charge as quickly when they are not in use, which means less frequent recharging is required. The self-discharge rate of lithium-ion batteries is only 3.5% per month, which is much less than that of lead-acid batteries.
Lightweight: Compared to lead-acid batteries, lithium-ion batteries are much lighter since their high energy density, making them ideal for portable applications.
Maintenance free：Lithium batteries require no maintenance, saving maintenance time and costs.
Environmentally friendly: Compared to lead acid batteries, the components of lithium batteries are environmentally friendly, causing no pollution.
● Lead acid battery packs
Bulkier: Compared to lithium-ion battery packs of comparable capacity, lead acid battery packs are heavier and bigger.
Leaner lifespan: Lead acid batteries have a leaner life and might need to be replaced more frequently.
Less effective: They are less effective at storing and discharging energy.
Frequent maintenance: The electrolyte of lead-acid batteries is lead-acid, which is prone to leakage or freezing in winter, so maintenance is required every 3-6 months.
Pollution: Lead-acid will pollute the environment.
Therefore, Due to their higher energy density, longer cycle life, lower self-discharge rates, and lightweight design, 12V lithium-ion battery pack are the better option for the majority of applications.

FAQs about 12V lithium-ion battery packs
How to make a 12V 18650 battery pack
Creating a 12V 18650 battery pack involves selecting and connecting multiple 18650 lithium-ion cells in the appropriate configuration. Here are the general steps:
- Gather the required number of 12v 18650 battery cells with the same capacity and voltage.
- Decide on the desired capacity (Ah) and voltage (12V).
- Connect the cells in series by soldering or using battery holders, ensuring proper polarity.
- Install a suitable BMS to manage the cells and provide protection.
- Enclose the cells in a protective casing.
- Connect the 12v 18650 battery pack to your intended application, ensuring proper wiring.
How to connect 4 12V batteries to make 24V
To create a 24V battery bank from four 12V batteries, follow these steps:
- Connect the first pair of batteries in series. The remaining terminals are used as the 24V output.
- Join the positive and negative terminals together to connect the last two pairs in parallel. A 24V battery bank with the capacity of all four batteries will be produced by this configuration.
How long does it take to charge a 12V battery at two amps?
The capacity and current state of charge of the battery determine how long it will take to charge a 12V battery at 2 amps. To estimate the charging time, you can use the formula:
Charging Time (hours) = (Battery Capacity in Ah) / (Charging Current in Amps)
For example, if you have a 12V battery with a capacity of 50 Ah and you are charging it at 2 amps:
Charging Time = 50 Ah / 2 A = 25 hours
It would take approximately 25 hours to fully charge the 50Ah battery at a 2-amp charging rate.
How long will a 12V battery last with an inverter?
The duration a 12V battery will last when powering an inverter depends on several factors, including:
- Battery capacity (Ah): A higher-capacity battery will last longer.
- Inverter efficiency: Inverters are not 100% efficient; some energy is lost as heat during the conversion process.
- Load: The power requirements of the devices connected to the inverter.
To estimate the runtime, you can use the formula:
Runtime (hours) = (Battery Capacity in Ah) / (Inverter Load in Watts x Inverter Efficiency)
For example, if you have a 12V battery with a capacity of 100Ah, an inverter with an efficiency of 90%, and you are powering a 300W load:
Runtime = (12v x 100 Ah) / (300W x 0.90) = approximately 4.44 hours
The battery would last approximately 4.44 hours under these conditions.
