Engineered with 50G shock resistance, IP68 sealing, and I2C power monitoring for next-gen pet trackers
🛡️ Field-Tested Ruggedness: Solving Severe Physical Impact & Water Ingress in Pet Electronics
Outdoor pet training collars and hound trackers face extreme mechanical stress—from violent running impacts and intense biting to continuous submersion in rainy mud. Standard shrink-wrapped battery packs frequently suffer from cell puncturing, internal weld fractures, or moisture-induced short circuits. To overcome these industry vulnerabilities, HiMAXBATT engineered a custom dual-color PC+ABS plastic hard-shell casing measuring 54.0mm x 38.0mm x 12.5mm and weighing just 42.0g. Inside the enclosure, precision-cut EVA shock-absorbing foam fully cushions the 1S1P lithium polymer core against sudden acceleration. Integrated screw mounting slots guarantee rigid mechanical locking within the main device body. Proven by rigorous laboratory validation, this assembly survives 50G mechanical shocks, 2-meter drop tests on concrete across 12 contact faces, and high-pressure IP68 water sealing tests. Equipped with a strain-relieved JST-XHP 2.54mm 3-Pin connector, it guarantees absolute operational integrity for high-end hunting and working dog collars.
⚡ Intelligent Telemetry & High-Density Performance: Eliminating Sudden Power Shutdowns
Reliable tracking relies on intelligent battery management. Standard batteries often trigger premature voltage cutoffs when high-current accessories—such as vibration motors, high-decibel buzzers, and cellular GPS chips—fire simultaneously. The HiMAXBATT battery pack utilizes the highly mature LP103450 prismatic LiPo cell (10mm x 34mm x 50mm), delivering 3.7V nominal voltage and an expansive 1800mAh (6.66Wh) capacity. Operating within a discharge cutoff range of 2.75V to a 4.2V fully charged state, it supports up to 1.8A (1.0C) continuous discharge to sustain multi-module power spikes without severe voltage sag. Crucially, the embedded protection circuit incorporates SMBus and I2C smart communication protocols alongside a 10k NTC thermistor. This enables the collar host MCU to query real-time State of Charge (SoC), State of Health (SoH), and cell temperature. Operating reliably across -20°C to 60°C discharge temperatures, charged safely via 0.9A (0.5C) standard current, and built to exceed 500 charge cycles at over 80% capacity retention, this unit fully aligns with UN38.3, CE, FCC, IEC 62133, and UL2054 standards

Frequently Asked Questions
Engineering custom power solutions for intelligent pet devices requires balancing mechanical durability, chemical stability, and telemetry accuracy. Below are answers to frequent technical questions from product engineers and procurement managers regarding our 3.7V 1800mAh smart collar battery solution.
Why use a dual-injection PC+ABS hard shell instead of standard PVC shrink film for pet collar batteries?
Pets, especially medium-to-large breeds and hunting dogs, subject tracking collars to severe biting, clawing, and impacts against outdoor terrain . Standard PVC shrink film offers no structural protection, risking mechanical punctures to the soft pouch cell that cause internal short circuits or fires. Our PC+ABS hard shell with internal EVA foam absorbs up to 50G mechanical shock and survives 2m concrete drops, protecting the internal LP103450 cell while providing screw mounting points for seamless enclosure integration.
How does the SMBus / I2C communication protocol prevent sudden pet tracker power failures?
Traditional voltage-based battery indicators miscalculate charge levels when high-power components (GPS cellular transmission, vibration motors) cause temporary voltage dips . The embedded fuel gauge IC in our battery pack uses SMBus/I2C communication to stream real-time State of Charge (SoC), State of Health (SoH), and temperature data directly to the device MCU . This enables smart low-power algorithms to manage cellular ping rates before critical depletion occurs.
Is the LP103450 1800mAh LiPo battery capable of sustaining continuous power bursts without thermal throttling?
Yes. Built on the industrial-grade LP103450 prismatic platform, this 1S1P configuration supports a maximum continuous discharge current of 1.8A (1.0C), which far exceeds the typical combined load (~0.5A – 1.2A) of high-power vibration motors, bright warning LEDs, and GPS telemetry modules . The internal 10k NTC thermistor continuously monitors internal temperature, enabling the protection board to safeguard the cell across discharge temperatures from -20°C to 60°C.
What international compliance and safety certifications does this battery pack meet?
The battery pack is manufactured in strict accordance with ISO9001 quality systems and complies with global regulatory standards including UN38.3 (transport safety), CE, FCC, IEC 62133 (portable lithium safety), and UL2054 (household and commercial battery safety) . All materials meet RoHS and REACH environmental standards for safe international distribution.
Can HiMAXBATT customize the output connector, cable length, or thermistor parameters for our proprietary PCB?
Absolutely. While our standard design utilizes a JST-XHP 2.54mm 3-Pin connector with a 10k NTC thermistor , HiMAXBATT provides complete OEM/ODM engineering support. We can adapt cable lengths, wire gauges, thermistor B-values, and connector brands (e.g., Molex, Hirose, JST) to match your custom mainboard layout.
