Ultra-Compact 52g Carbon-Nylon Frame: Designed for seamless anatomical embedding inside forearm sockets without spatial pinch or thermal discomfort.
10A Instant Peak Burst Output: Powering multi-joint micro-servos simultaneously to execute rapid, high-torque grip and pinch maneuvers without voltage sag.
1% High-Precision I2C Fuel Gauge: Integrated TI BQ27441 chip providing real-time SOC tracking and sub-10μA standby power to prevent unexpected power loss.
In upper-limb prosthetics, every millimeter and gram dictates user fatigue and long-term wearability. Built upon two 3.7V HIMAX LP-603048 soft-pack cells in a 2S1P configuration, this 7.4V 1200mAh (8.88Wh) battery features an ultra-thin 13.5mm profile and weighs just 52 grams. Encapsulated within flame-retardant PVC and a 3D-printed carbon-nylon skeletal skeleton, it fits smoothly into narrow forearm sockets without compromising internal physical layout. Engineered in alignment with ISO9001 cytotoxicity non-toxic evaluation standards and CE-MDR directives, it eliminates skin irritation risks while providing clean, reliable energy for daily prosthetic operation.
⚡ Section 2: High-Torque Servo Response & Intelligent Power Management
Driving multi-finger myoelectric hands requires rapid energy discharge to support simultaneous micro-servo motor actuation during heavy gripping. Our medical-grade ultra-thin LiPo chemistry delivers up to 10.0A peak discharge (1 second) and 5.0A continuous current without suffering internal impedance voltage sags. To completely eradicate wearer battery anxiety, the pack incorporates a Texas Instruments BQ27441 coulomb counter IC communicating via I2C / SMBus through a JST-PH-4P micro locking connector. This system delivers State-of-Charge (SOC) tracking accurate to 1% while consuming under 10μA in standby. Batch-verified through 1.5m 21-angle drop impacts and nail penetration puncture testing, this pack is fully UN38.3 transport certified and produced in an ISO9001 certified environment.

Frequently Asked Questions
Engineering next-generation myoelectric bionic hands requires solving tough trade-offs between physical spatial constraints, surge release for servo motors, and absolute wearing safety. Below are technical answers to the most common questions raised by prosthetic design engineers and clinical equipment sourcing teams.
How does this 7.4V battery handle sudden current spikes during multi-finger power gripping?
Our LP-603048 cell features ultralow internal resistance (≤15mΩ per cell) and high-rate LiPo chemistry, allowing the 2S1P pack to deliver 10.0A peak discharge bursts (1 second) and 5.0A continuous output without severe voltage drops, ensuring smooth multi-servo execution.
Is this battery safe for direct integration into skin-contact wearable forearm sockets?
Absolutely. The pack is enclosed in flame-retardant PVC and a 3D-printed carbon-nylon skeletal frame. It is manufactured to pass ISO 10993 cytotoxicity biocompatibility evaluation and CE-MDR wearable standards, preventing skin irritation and minimizing heat conduction.
How accurately can users track remaining battery life to avoid sudden shutdown?
The pack integrates a Texas Instruments BQ27441 fuel gauge IC communicating via I2C / SMBus, reporting State-of-Charge with up to 1% precision. It operates with sub-10μA standby current to preserve runtime during idle storage.
What official transport and safety test certifications accompany this product?
The product holds official UN38.3 transportation certification and is manufactured in ISO9001 certified facilities. Additionally, it is tested to comply with IEC 62133-2, CE-MDR, RoHS 2.0, REACH, and undergoes 1.5m drop and nail penetration safety verification.
Can HiMAXBATT customize dimensions, cable lengths, or connectors for our OEM prosthetic project?
Yes. HiMAXBATT offers complete OEM/ODM engineering support. We can adapt cell capacity, adjust wire length, modify connectors (e.g., Molex, Hirose, JST), or redesign the carbon-nylon skeletal frame to match your exact socket geometry.
