Seamless compatibility design

- Accurate size matching : The appearance and interface position of the lithium battery module are completely consistent with mainstream lead-acid battery modules, achieving true "change and use"
- No modification assembly : Retain the original battery box, wiring terminals, and installation structure, and upgrade process does not require any structural adjustments
- Flexible configuration : Supports modular combination of common voltage systems such as 12V, 24V, 36V, 48V, etc

 

Excellent performance improvement

-Capacity doubling: Under the same volume, the energy density is increased to more than three times that of lead-acid batteries,
- Ultra long lifespan : 1500 deep cycle life, far exceeding the 300-500 cycle standard of lead-acid batteries
-Stable output : The basic unit has a nominal voltage of 12.8V, a high-capacity configuration of 42Ah, and a wide operating temperature range (-20 ℃~60 ℃)

 

 

1. Maximizing asset utilization

The shell, connector, and installation bracket of lead-acid batteries usually account for 20-30% of the overall cost, and the service life can reach more than 10 years. The upgrade of traditional lithium batteries has resulted in the disposal of these "still young and middle-aged" components, causing significant waste of resources. Our plan maximizes the value of every existing investment.

 

2. Gradual upgrade with controllable risks

For large energy storage systems or fleet users, one-time overall replacement faces enormous financial pressure and operational interruption risks. Jixin solution supports:
- Pilot verification : Upgrade 1-2 sets of batteries first to verify their effectiveness
- Batch implementation : gradually replace by quarter according to budget

 

3. Supply chain resilience assurance

Traditional whole replacement relies on a single supplier for "black box" products. Our modular design ensures:
 Module level spare parts inventory, rather than complete battery spare parts
 Quick on-site replacement, no need to return to the factory for repair

 

4. Technology iteration friendly

The technology of lithium-ion batteries for electric vehicles is still developing rapidly, and there may be higher energy density and lower cost battery cells in the future. Our modular architecture supports "technological iteration and upgrading" - in the future, only replacing the internal battery cells of the module can enjoy the benefits of technological progress, without the need to replace the casing and connection system again.

 

5. The True Practice of Environmental Responsibility

The most difficult part of lead-acid battery recycling is not the recycling of lead plates, but the environmentally friendly disposal of plastic shells. Our plan avoids the premature disposal of millions of tons of engineering plastics and truly reduces electronic waste from the source.

 

6. Maintain system familiarity

Operators do not need to relearn new maintenance procedures, charging standards, or fault diagnosis methods. The original operation manual, safety regulations, and maintenance tools continue to be applicable, significantly reducing training costs and safety risks.

 

 

Convenient upgrade

Suitable for all fields that use standard lead-acid batteries, such as electric bicycles, electric vehicles, electric forklifts, solar energy storage systems, UPS backup power supplies, RV energy storage, golf carts, etc. Users only need to select the corresponding number of lead to lithium modules for replacement based on the original specifications of lead-acid batteries.

 

Industrial sector: Intelligent upgrade of electric forklifts

- Challenge : Large logistics centers have hundreds of forklifts, and there is a huge financial pressure on the overall lithium battery upgrade
- Solution : Implement in batches, prioritize upgrading high-frequency vehicles
- Effect : Charging time reduced from 8 hours to 2 hours, achieving "meal time charging, all day operation"

 

Special vehicles: electric bicycles, golf carts, sightseeing vehicles
-Challenge: The vehicle design is compact, and the overall lithium battery size does not match the original installation position
- Solution : In situ replacement, perfectly utilizing the existing battery compartment space
-Effect: Range increased from 50 kilometers to 150 kilometers, meeting all day operation needs

 

Cost benefit analysis
-Initial investment : More than 40% cost savings compared to a brand new lithium battery system
- Cost of use : 70% reduction in electricity cost per kilowatt hour during the lifecycle
-Maintenance Cost : Maintenance free design, no need for regular water replenishment and other maintenance operations
-Space Value: Under the same capacity requirement, it can reduce 2/3 of the battery space occupied

 

Safety and reliability
-Using automotive grade lithium iron phosphate battery cells, the thermal stability far exceeds that of lead-acid batteries
-Built in intelligent BMS system, real-time monitoring of the status of each battery cell
-Module level independent protection to prevent the spread of system level faults
-Through multiple safety tests such as overcharging, needle punching, and squeezing

 

Environmental Value
-Upgrade instead of discarding: Extend the lifespan of existing battery packs and reduce electronic waste
-Energy efficiency improvement: Charging and discharging efficiency reaches over 95%, reducing energy waste
-Material environmental protection: lead-free, cadmium free and other heavy metal pollution

 

Note: Please consult a professional technical team for specific configuration plans, and confirm device compatibility before installation. This product is only used to replace standard lead-acid battery modules and is not suitable for non-standard or special structure battery systems.
