What is a 24V Lithium Battery

It is a 24v rechargeable battery. Its cathode material is generally lithium iron phosphate or ternary lithium, and graphite is commonly used as the anode material. A complete 24V lithium battery mainly consists of three core parts: lithium cells, BMS, and supporting structures.

24 volt battery connection

For LiFePO4 batteries, 8 cells are typically wired in series to form a 25.6V battery pack. It has a full charge voltage of 29.2V, maintains an operating voltage of 24V–26V when discharging within 20%–80% capacity, and features a standard discharge cut-off voltage of 20.0V.
Alternatively, 7 ternary lithium cells can be connected in series, with a nominal voltage of 25.9V, a full-charge voltage of 29.4V, and a discharge cut-off voltage of 21.0V. Compared with LiFePO4 batteries, ternary lithium offers higher energy density, delivering smaller size and lighter weight at the same capacity.
When restricted by equipment battery compartment size or structural layout, you can use two 12 volt batteries to make 24 volts, which adapts well to irregular installation spaces.

Request Custom BMS

Cell Balancing

Our self-developed intelligent BMS supports 50–100mA passive balancing and 1–5A active balancing. It automatically corrects capacity deviations between cells, mitigates consistency degradation after long-term cycling, and extends the overall service life of the battery pack by up to 30% or more.

Precise Voltage Protection

The BMS is engineered to strictly align with the operating voltage range of the 24v battery system, with tiered settings for overcharge and over-discharge protection thresholds and recovery logic. This is a core mechanism to ensure full compatibility between the battery’s output voltage and legacy 24V equipment, while preventing cells from operating outside their safe range and shortening service life.

Tiered Current Protection

When a 24 volt inverter or other 24V systems power on, they generate a surge current several times the magnitude of the continuous current. A high-performance BMS protects cells from damage caused by high-current surges.

Protection thresholds can also be customized to match equipment operating conditions, with three tiered current protection levels: continuous discharge, peak discharge, and short circuit.

Condition-Adapted Temperature Protection

By monitoring temperatures of the cells, MOSFETs, and ambient environment, the BMS adjusts battery output power in real time to prevent lithium plating during low-temperature charging and high-temperature induced thermal runaway.

An intelligent BMS can integrate low-temperature heating and high-temperature cooling functions, maintaining an optimal internal temperature range of 15°C to 25°C for the battery pack across ambient temperatures from -20°C to 60°C.

Industrial-Grade Protection Design

The outer housing and supporting structure are critical factors determining a battery’s adaptability to various working environments. Our 24v li ion battery has received comprehensive upgrades to both its internal structure and outer casing.

Dual-Material Housing Options

The ABS 24v battery box is crafted from industrial-grade high-strength material, effectively resisting impacts from heavy objects and other physical shocks. Eco-friendly flame retardants are added to suppress flame spread while ensuring the material is non-hazardous and environmentally compliant. You can also choose a thickened metal battery housing for higher structural strength. It comes with anti-corrosion surface treatment and uses compressed sealing gaskets at all joints to achieve an IP67 protection rating, though it increases the overall battery weight.

12v vs 24v vs 48v battery: What Are the Differences?

Voltage is the core foundational parameter of a power supply system, as it directly dictates the system’s load capacity, overall efficiency, and build cost. Therefore, voltage selection must be considered upfront when designing a power supply system.

Get Voltage Selection Advice
12V vs 24V vs 48V Batteries

Operating Current and System Efficiency

When system power is fixed, higher voltage corresponds to lower current. According to Joule’s Law, heat loss follows the formula P = I²R, which means higher current usually leads to greater line loss.

Since 24V systems require lower current than 12V ones, cables generate less heat and suffer lower energy loss during equipment operation, resulting in higher overall system efficiency.

24V battery current rating

Cost of Cables and Electrical Components

While higher voltage improves efficiency, it also requires more sophisticated system design for safety protection, so you will spend more on hardware, including inverters, BMS, circuit breakers, and insulation components.

This means you should never blindly pursue high voltage when designing a voltage platform. It is necessary to comprehensively weigh multiple factors such as system efficiency, production cost, and actual usage requirements.

24V Battery Capacity Selection Guide

To pick the right 24v lithium battery capacity, you need to calculate the required value based on actual load parameters with the following formula:

Required Capacity (Ah) = Total Equipment Power (W) × Expected Runtime (h) ÷ System Nominal Voltage (25.6V) ÷ Depth of Discharge (recommended 0.8–0.9) ÷ System Conversion Efficiency (recommended 0.85–0.9)

Calculate Your Capacity

Example Calculation

For example, suppose you complete a battery retrofit for a truck fleet to support 5 hours of parking air conditioner use. The parking air conditioner has a power of 800W, paired with a lithium battery featuring an 80% depth of discharge and 90% conversion efficiency. The calculation is derived as follows:

800W × 5h ÷ 25.6V ÷ 80% ÷ 90% ≈ 217 Ah

If you also account for the impact of environmental factors on the air conditioner and set aside an additional 20% capacity as a buffer, the required capacity comes to 271Ah. This specification can fully and reliably meet all usage demands. For scenarios that only need to cover basic power requirements, the 200Ah model can serve as the baseline configuration for retrofit projects.

24V Battery Manufacturing Process

Frequently Asked Questions

Yes. Parallel connection is typically adopted to increase total capacity while maintaining the same system voltage, while series connection is used to raise the system voltage without changing the total capacity.

However, you must ensure strict consistency in voltage, capacity, and internal resistance across all batteries during system modification. Excessive voltage difference will trigger uncontrolled circulating current in parallel configurations, causing battery overheating or even swelling. Batteries with mismatched capacity and internal resistance in series will lead to inconsistent charging and discharging of individual units in the system, accelerating battery degradation.

It depends on the specific lithium electrochemical system and your customized capacity requirements. To meet the 24V nominal voltage requirement, lithium iron phosphate (LiFePO4) batteries usually adopt an 8-cell series (8S) configuration, while ternary lithium batteries use a 7-cell series (7S) setup.

Parallel configurations are also applied based on the capacity of a single cell. Take LiFePO4 batteries as an example: to achieve 100Ah capacity with 100Ah large-format cells, only 8 cells connected in series are needed. For 50Ah cells, two 24V series packs need to be connected in parallel to reach 100Ah, requiring a total of 16 cells.

The specific 24v battery weight is subject to the battery’s rated capacity, customized additional functions, as well as the material of the battery enclosure. Below are the weight specifications of our 24V lithium batteries with ABS housings.

This question covers two scenarios: single-charge runtime and overall service life. If you refer to the runtime per full charge, it is related to the load power of your equipment and can be calculated with the following formulas:
Runtime (h) = Usable battery energy (Wh) ÷ Equipment power (W)
Usable battery energy (Wh) = Battery voltage (V) × Battery capacity (Ah) × Depth of Discharge (DoD)
If you refer to the overall service life, it varies by battery chemistry. LiFePO4 batteries have a cycle life of up to 6,000 cycles and can serve for 6 to 10 years under normal operating conditions. Ternary lithium batteries feature higher energy density but a shorter cycle life of 3,000 cycles, with a typical service life of 5 to 8 years.
The battery management system is critical to battery safety and also affects the operational stability of the entire equipment.
Essential basic functions include overcharge/over-discharge voltage protection, graded overcurrent and short-circuit protection, high/low temperature protection for charging and discharging, and passive/active cell balancing.
Advanced functions include compatibility with mainstream industrial communication protocols, including CAN, RS485, and SMBus, which supports integration with upper-level systems such as controllers and monitoring platforms, enables accurate SOC/SOH estimation, and delivers real-time upload of equipment status data.
A dedicated lithium battery charger or a matching 24V photovoltaic inverter must be used for charging. Do not use lead-acid chargers, as this will cause irreversible damage to the battery. Please also follow the correct operation sequence: connect the charger to the battery first, then turn on the power supply. After charging is completed, cut off the power supply first, then disconnect the charger from the battery.
