Config: 2S5P · Energy: 148Wh · Discharge: −20°C to 60°C · Cycle life: 300+
An electric bicycle brand needed a high-capacity, lightweight battery to extend per-charge range without increasing frame weight. HIMAX assembled 21700 cells in a 2S5P layout, delivering 7.4V nominal voltage and 20Ah capacity (148Wh). The five-parallel configuration reduces per-cell stress and voltage sag under load, supporting the motor’s peak current demand during acceleration. Max charge and discharge currents are both 3A per cell, with a working temperature range of −20°C to 60°C for year-round reliability. The slim cylindrical pack is sized to fit within the bike’s down tube housing with custom connector and wire length.
Model: HLIGB02-0005-1447 · Energy: 36Wh · Dimensions: H23.5×D22×L153mm · Weight: 140g
A logistics equipment supplier needed a reliable, long-shift battery for handheld barcode scanners used in warehouse environments. HIMAX supplied an INR21700-50E 2S1P pack at 7.2V / 5Ah (36Wh), weighing just 140g and measuring 153mm — engineered to fit inside the scanner’s grip handle. The three-level overcharge and over-discharge PCM ensures safe operation across a full 8-hour shift. Max continuous discharge is 3A; the −20°C to 60°C operating range handles both cold-storage warehouses and outdoor dock areas. Certified to GB/T18287-2013, UL1642, and CE61960.
Model: 36-4BP · Cell: Samsung INR21700-40T · Energy: 14.4Wh · Dimensions: D22×H75.6mm
A consumer electronics OEM required a high-drain single-cell pack for a regulated vaping mod demanding instantaneous high current. HIMAX supplied a Samsung INR21700-40T 1S1P pack at 3.6V / 4000mAh (14.4Wh), with a max continuous discharge of 4A and an internal impedance of ≤15mΩ — minimising voltage drop at peak draw. The compact D22×75.6mm form factor is a direct fit for standard 21700 mod tube housings. The PCM provides overcharge protection (4.28V cutoff) and over-current protection (8–16A trip). Certified to GB/T18287-2013, UL1642, and CE61960.
