Thermal Printer Heating-Head Current Pulses (2S 7.4V)
Printing dense black QR codes and receipts on a 58mm or 80mm thermal line head pulls 3 A–6 A pulse bursts; 2S1P 18650 (2550mAh–3200mAh) cells prevent voltage resets mid-receipt.
1S1P / 1S2P (3.6V) vs 2S1P (7.2V) Handle Cavity Geometry
Pistol-grip barcode scanners and handheld POS terminals house 1 or 2 cylindrical 18650 cells inside the ergonomic grip or rear snap-in battery door.
10kΩ / 47kΩ NTC Thermistor & Gold Spring-Blade Contacts
Handheld terminals use 3-pad or 4-pad gold-plated spring-finger contacts (B+, NTC/ID, B-) or JST 3-pin wire harnesses for drop-in cradle charging.

TECHNICAL REFERENCE
POS Terminals, Barcode Scanners & Handheld PDAs Battery Engineering FAQs
Why do POS terminals with built-in thermal receipt printers use 2S (7.4V) 18650 packs instead of 1S (3.7V)?
Thermal printheads require 7.2V–8.4V to heat the platen dots rapidly at high print speeds (70–100 mm/s); a 2S1P EVE 18650 26V (2550mAh) or 29V (2850mAh) pack drives the printhead directly without boost-converter losses.
Which 18650 cell maximizes shift runtime for cold-chain warehouse barcode scanners?
EVE 18650 33V (3200mAh) and 35V (3500mAh) provide maximum Wh inside a standard 18×65 mm cylinder for 12-hour warehouse scanning shifts.
Can you supply bare 18650 cells as well as custom shrink-wrapped 1S/2S POS packs?
Yes. We supply factory-sorted bare EVE 18650 (26V/29V/33V/35V) cells by the carton as well as custom 1S/2S packs with NTC thermistors and PCB protection.
How do I match the NTC thermistor value for an existing POS charging cradle?
Specify whether your terminal mainboard expects a 10kΩ (B=3435K/3950K) or 47kΩ NTC resistor on the center contact pad when submitting your custom pack inquiry.
