3.7 V 4.6 Ah Split‑Cell Li‑ion Pack (1S2P of 18500‑2300 mAh Cells)
1. True Split‑Module Design: Two independent 18500 cells set 40 mm apart for ultra‑flexible mounting in narrow or irregular spaces.
2. Dedicated Protection Circuit: Each module ties into a unified PCB offering 4.2 V charge cut‑off and 3.6 V constant‑voltage discharge for safe, balanced operation.
3. Multi‑Port Connectivity: Three PH‑2P sockets let you power separate subsystems or daisy‑chain modules without extra wiring.
4. Color‑Coded Leads: 60 mm of redack color‑coded wiring (excluding plug) ensures error‑proof hookups.
5. Compact Footprint: Combined dimensions of 52 × 18.5 × 27 mm (per module) deliver 4.6 Ah capacity in a slim, lightweight form.
6. Storage Charge Option: Can be shipped at 30 % state‑of‑charge to maximize shelf‑life.
7. Environmental Compliance: Manufactured in an ISO 9001 facility, REACH‑compliant materials.
Custom Engineering & 100 % QC
At Himax we offer free DFM reviews and style‑guide mockups before you sign off. Each module undergoes 5‑step testing (voltage, IR, balance, charge/discharge curve, mechanical inspection) so you receive perfectly matched split‑cell assemblies every time—plus on‑demand prototyping and small‑batch runs.

Frequently Asked Questions
Lithium ion battery pack answers, if you do not find the answer you are looking for, please contact us.
We’ll get back to you within 24 hours.
1. What are the dimensions and capacity of this split‑cell pack?
It’s two 18500 2300 mAh cells (1S2P) spaced 40 mm apart for a combined 3.7 V 4.6 Ah, with each module measuring 52 × 18.5 × 27 mm.
2. Why choose a “split‑cell pack” over a traditional single‑module design?
Himax’s design lets you contour‑fit power into narrow or curved enclosures common in industrial and medical equipment.
3. What protection features are integrated into the PCB?
The PCB provides 4.2 V over‑charge cut‑off, 3.6 V constant‑voltage discharge, cell‑balancing bleed resistors, and an NTC thermistor check—each validated in Himax’s 5‑step QC process.
4. Is this industrial battery pack suitable for high‑volume OEM orders?
Yes—you can purchase factory‑direct bulk quantities with Himax’s tiered pricing, full DFM reviews, and on‑demand prototyping.
5. How does Himax handle quality control on split‑cell assemblies?
Each module passes voltage, internal resistance, balance, capacity and mechanical inspections. Himax’s ISO 9001 facility keeps full traceability from cell lot to final pack.
