Uncompromising Power for Night Trails & Hands-Free Work
Lightweight 16g Form Factor | 1.6A Continuous Output | Integrated NTC Temp Control
⚡ Precision Electrochemistry & Thermal-Aware Power Delivery for High-Lumen Wearables
In wearable illumination engineering, the primary design bottleneck is balancing high peak current demands against severe thermal and dimensional constraints. The HiMAXBATT LP603040 3.7V 800mAh (2.96Wh) soft-pack Lithium Polymer battery pack is engineered specifically to eliminate this compromise. Constructed from high-density 1S1P pouch cells with an internal resistance of ≤130mΩ, this compact unit sustains a continuous discharge current of 1.6A (2.0C). This capability directly supports modern LED driver circuits during high-lumen turbo modes without inducing severe voltage droop. To address LED heat transference inside compact lamp housings, the pack integrates an analog NTC thermistor (10KΩ 1% B3950) alongside positive and negative supply leads. Routed through a JST-PH 2.0mm (or JST-SH 1.0mm) 3-pin connector, this signal line allows the headlamp mainboard MCU to execute real-time thermal throttling, protecting both electrochemistry and driver electronics during prolonged high-output illumination.
Wearable headlamps and camp chest lights operate in harsh environments where perspiration, ambient rain, and accidental impacts are constant threats. Measuring just 6.3mm × 30.5mm × 42.5mm and weighing only 16.0g, the HiMAXBATT battery pack utilizes a custom black PVC heat-shrink sleeve with specialized glue potting at the wire-exit junction. This structural sealing shields the internal PCM circuit board against sweat corrosion and moisture intrusion. Designed in strict compliance with ISO9001 manufacturing protocols and certified under UN38.3, IEC 62133-2:2017, CE-EMC, RoHS, and REACH standards, each batch undergoes exhaustive validation. Factory testing verifies complete structural safety after 1.2-meter six-face drop impacts, full overcharge/overdischarge protection cutoffs, and 50°C high-temperature fully-charged storage tests. The result is an OEM power solution engineered to maintain ≥80% capacity retention over 500 charge cycles, providing outdoor equipment manufacturers with an instantly deployable, trustworthy energy core.

Frequently Asked Questions
Navigating battery selection for wearable LED headlamps requires careful alignment between electrical output, thermal management, and mechanical durability. Below, our engineering team answers five essential technical questions frequently raised by product designers and procurement specialists integrating the HiMAXBATT LP603040 power pack into high-performance portable lighting devices.
How does the integrated 10K NTC thermistor communicate with our headlamp's driver board?
The 3-pin JST output terminal includes dedicated V+, V-, and NTC signal lines. The NTC thermistor (10KΩ ±1%, B3950) changes resistance dynamically based on battery temperature. Your mainboard MCU reads this resistance across an analog input pin, allowing firmware to initiate power foldback if temperatures approach thermal limits, preventing overheating during continuous high-lumen operation.
Can this 800mAh battery support momentary high-power turbo brightness modes above 1.5A?
Yes. The LP603040 electrochemistry features low internal resistance (≤130mΩ) and is rated for 1.6A (2.0C) continuous discharge. It reliably powers driver bursts up to 5.9W output without causing sudden low-voltage cutoff triggers on the PCM protection circuit.
How does the wire lead potting protect the battery pack from sweat and outdoor weather?
Sweat and rain can wick along wire leads into the PCM circuit board, causing shorts or corrosion. HiMAXBATT applies a high-grade moisture-proof potting compound at the wire exit under the PVC shrink sleeve, creating an ingress barrier that passes rigorous humidity and 1.2m drop vibration testing.
What certifications and test reports are available for international customs and shipping?
The LP603040 battery pack complies with UN38.3 transport safety regulations (including thermal, altitude, and shock testing), IEC 62133-2:2017 safety criteria for portable lithium cells, CE-EMC, and RoHS/REACH environmental standards. Full test reports are provided to streamline global compliance approval.
What are the standard lead times and wire/connector customization options for OEM orders?
Because LP603040 is a mature, high-volume standard cell footprint, raw cells are consistently stocked. Standard samples ship in 3–5 days, and mass production lead times average 15–20 days. We offer full customization for lead lengths, insulation sleeving, and terminal connectors (such as JST PH 2.0mm, JST SH 1.0mm, or Molex equivalents).
