How to Turn Application Conditions into Battery Specifications for Solar, Agriculture, and E-Mobility

The most common battery procurement mistake is choosing voltage and capacity before defining the operating scenario. The reliable sequence is different: map the project conditions first, then convert those conditions into battery chemistry, system voltage, capacity, and verification steps. This article explains how to do that using the HAIYOU product range from Jiangxi Jinhaiyou New Energy Resources Technology Co., Ltd., including household energy storage lithium batteries and power batteries for electric two-wheelers, electric tricycles, and low-speed four-wheelers.

Problem Definition: Why Scenario Matching Matters

A battery specification that looks correct on paper can fail quickly in the field if the project environment is ignored. For example, an outdoor agriculture project creates a very different stress profile than an indoor stationary storage project. The Agriculture & Garden Industry application environment is described as outdoor open-air, high-temperature, dusty, and frequently vibrating. Equipment such as backpack agricultural sprayers, water pumps, and irrigation motors needs a battery that can maintain stable performance while moving and charging repeatedly.

For off-grid residential solar energy storage projects, the battery has a different job. It must store electric energy and provide stable DC power output. It also needs to provide continuous power to equipment and serve as an emergency backup power supply. If a buyer chooses a battery based only on price or voltage, these functional and environmental requirements can be missed.

Industry Background: Battery Demand Is Expanding Across Project Types

The global battery industry continues to grow across both stationary storage and mobility. According to Grand View Research, the global lithium-ion battery market was valued at USD 68.7 billion in 2025 and is projected to reach USD 306.2 billion by 2033. Fortune Business Insights expects lithium-ion batteries to account for 99.33% of the battery energy storage system market by 2026. In the mobility segment, Precedence Research estimated the global e-bike battery market at USD 10.8 billion in 2024, with a projected CAGR of 14.1% through 2034.

For buyers evaluating project-specific solutions, two additional data points are relevant. The traction battery market was valued at USD 43.29 billion in 2024, with lead-acid variants remaining popular in industrial sectors due to cost-effectiveness. The global golf cart battery market reached USD 1.49 billion in 2024, driven by a pivot from lead-acid to lithium-ion technology. Together, these trends show why buyers need a clear framework for matching battery products to the actual project scenario rather than relying on generic specifications.

Detailed Solution: HAIYOU Product Families for Scenario Matching

Jiangxi Jinhaiyou New Energy Resources Technology Co., Ltd. was established in 2005 and operates two factories: one produces lead-acid battery, and the other produces lithium battery. The company specializes in research, development, manufacturing, and sale of battery and energy storage products. Its main products include lithium batteries for two-wheeled electric vehicles, lithium batteries for tricycles and low-speed four-wheel vehicles, household lithium iron phosphate energy storage batteries, new-generation lithium batteries, and rack-mounted lithium batteries.

Household Energy Storage Lithium Battery

For buyers searching for a solar battery or an energy storage battery, HAIYOU offers household energy storage lithium batteries in two specification groups. The first group has a rated voltage of 12V or 24V and a rated capacity of 100Ah, 200Ah, or 300Ah. The second group covers rated energy from 2.56kWh to 16kWh, with available options of 2.56kWh, 5.12kWh, 10kWh, 14kWh, and 16kWh. Both groups use lithium iron phosphate chemistry. The cathode material is lithium iron phosphate, the basic shell material is industrial plastic or a metal frame, and the internal core is a lithium-ion cell.

Power Battery for Electric Two-wheeler

For e-mobility projects in the electric two-wheeler segment, HAIYOU provides power batteries with a voltage range of 48V, 60V, or 72V and a capacity range of 20Ah, 30Ah, or 40Ah. The chemistry types are NCM or LFP. These batteries also use an industrial plastic or metal frame shell with a lithium-ion cell core. Buyers should match the voltage to the vehicle platform and confirm the cycle-life expectation for the specific usage pattern.

Power Battery for Electric Tricycle and Low-Speed Four-wheeler

For electric tricycles and low-speed four-wheel vehicles, HAIYOU offers LFP power batteries with a voltage range of 60V or 72V and a capacity range of 80Ah, 100Ah, 180Ah, or 300Ah. These larger-capacity batteries suit applications that need longer runtime or heavier load support. The cathode material is lithium iron phosphate, and the internal core is a lithium-ion cell.

Step-by-Step Breakdown: From Project Profile to Battery Specification

1. Define the function. For off-grid residential solar storage, the product must store electrical energy and provide stable DC power output. For equipment operation, it must provide continuous power and serve as an emergency backup power supply.
2. Map the operating environment. If the installation is outdoors with high temperature, dust, and frequent vibration, this must be written into the request. These conditions affect chemistry and enclosure choices.
3. Choose the chemistry family. LFP is used when long cycle life and stability under vibration are required. The HAIYOU electric two-wheeler line also offers NCM/LFP options for different vehicle requirements.
4. Size voltage and capacity. For household storage, choose from 12V/24V and 100Ah/200Ah/300Ah, or from 2.56kWh to 16kWh. For electric two-wheelers, choose 48V, 60V, or 72V and 20Ah, 30Ah, or 40Ah. For electric tricycles and low-speed four-wheelers, choose 60V or 72V and 80Ah, 100Ah, 180Ah, or 300Ah.
5. Confirm customization requirements. HAIYOU supports OEM and customized service for voltage, capacity, shell color, product logo, and appearance design. This is important when a project needs a specific visual identity or mounting layout.
6. Qualify and test before scaling. HAIYOU performs full inspection before delivery and strict performance and safety testing. Buyers should still request a sample and test it under the intended working conditions.

Use Cases

Off-Grid Household PV and Villa Backup

In one documented case, a household energy storage importer and distributor used HAIYOU products for off-grid household photovoltaic power storage and emergency backup power for villas. The project achieved long-cycle stable power supply and effectively solved power outage troubles for rural families. The highlighted attributes were high safety, long cycle life, lightweight design, and wide temperature adaptation.

Agriculture and Garden Equipment

The Agriculture & Garden Industry is a target application for HAIYOU power and energy storage batteries. The operating environment is outdoor open-air, with high temperature, dust, and frequent vibration. Matched equipment includes backpack agricultural sprayers, water pumps, and irrigation motors. The operation mode is cycle charge and discharge mobile operation. The application requires a long cycle life of at least 6,000 cycles and stable performance under frequent vibration. This makes cycle-life validation and vibration-related testing essential before moving to bulk orders.

E-Mobility Project Portfolio

For electric two-wheeler projects, HAIYOU offers power batteries at 48V, 60V, or 72V with 20Ah, 30Ah, or 40Ah capacity, in either NCM or LFP chemistry. For electric tricycles and low-speed four-wheelers, the power battery family includes 60V or 72V systems with 80Ah, 100Ah, 180Ah, or 300Ah capacity. These options allow buyers to match voltage and capacity to the vehicle platform and duty cycle.
