CUSTOM BATTERY SYSTEMS
From high-voltage systems at 96V and above to robots, quadruped platforms and BBU backup power, HOPPT develops cell, BMS and PACK configurations around defined loads, operating conditions and integration constraints.
Cell selection · BMS · PACK integration · Validation planning
CURRENT FOCUS
Explore four application directions: high-voltage systems, robots, quadruped robots, and battery backup units. Electrical ratings, mechanical fit, protection, and validation scope are defined for each project rather than assumed from a generic image.
ENERGY SYSTEMS
For projects using a higher DC bus or series-connected architecture, start with the operating voltage window, load profile, protection concept, and integration constraints.
MOBILE AUTOMATION
Robots need a battery matched to their movement cycle, charging rhythm, enclosure space, and communication interface. The design starts with how the machine actually works.
QUADRUPED PLATFORMS
Quadruped platforms can combine short power bursts with tight space and weight limits. Review runtime, mass, impact exposure, and battery replacement before defining a pack.
BACKUP POWER
For backup power in telecom or data infrastructure, define the required hold-up time, rack envelope, monitoring interface, and service expectations before choosing a configuration.
ENGINEERING & DELIVERY
Dongguan Hoppt Light Technology Co., Ltd. (HOPPT Battery) was established in 2017. Our core technical and project team has been engaged in lithium battery R&D and engineering applications since 2005.
Supported by production bases in Dongguan and Huizhou, we provide integrated services covering cell selection, BMS development, PACK design, thermal management, communication integration, testing, manufacturing and project delivery.
Testing and certification requirements are evaluated according to the specific product model, application, target market and applicable standards.
We start with the customer's actual equipment conditions and define the battery architecture around real project requirements.
Cell, BMS, electrical architecture, PACK, thermal management and communication are evaluated as one complete system.
Engineering samples, testing, equipment integration, pilot production and volume delivery are managed through a project-based process.
CELL-LEVEL REFERENCE DATA
Historical cell test curves show the type of evidence used in a battery review. Each graph applies to its stated cell and test conditions; it does not establish the performance of every custom battery pack. Request the relevant model report before design approval.

SYSTEM INTEGRATION
These archived 29.3 V / 60 A charger images illustrate one integration component. Charger selection, connector, protocol and protection settings must match the final pack design.
PUBLISHED APPLICATION EXAMPLES
These examples are drawn from HOPPT’s published product catalog. They identify an application and listed configuration; no customer outcome or independent certification is implied. Requirements and final specifications are confirmed project by project.
Published configuration for a biomimetic four-legged robot operating in a low-temperature environment.
72 V · 30 Ah · 2.16 kWh · ternary lithium-ion
Motor peak current, vibration, cold discharge, pack mounting and BMS limits need checking against the duty cycle.
Published configuration for an unmanned forklift; the source lists a low-temperature application.
150 V · 24 Ah · 3.6 kWh · LiFePO4
High-voltage isolation, charging interface, thermal conditions and any hazardous-area approval must be verified for the installation.
Published configuration for a pipe-corridor inspection robot with RS485 communication.
25.6 V · 20 Ah · 512 Wh · LiFePO4
Runtime, communication protocol, enclosure protection and charging access depend on the robot platform.

A useful first discussion connects the battery to the machine and its operating conditions. Share the information you have; open points can be identified during technical review.
Target voltage range, continuous and peak current, duty cycle, charging source, and required backup or runtime.
Available space, weight target, mounting method, connectors, and whether the pack must be removable.
Temperature range, vibration or impact exposure, storage conditions, and expected service pattern.
Applicable standards, test method, documentation needs, and the exact product configuration to be reviewed.
No. The application images show design directions; electrical ratings, dimensions, safety testing and documentation scope are confirmed for each specific project.
A target voltage range, load profile, required runtime or backup time, available space, operating environment, interface requirements, and expected project volume are a useful starting point.
Compatibility depends on the load, enclosure, controls, charging method, and safety requirements of each platform. A design should be reviewed against the actual application.
