3.6 V nominal, 2550 mAh cylindrical lithium-ion cell for compact 3S1P (2.55 Ah) and 3S2P (5.1 Ah) portable money counter and counterfeit detector battery packs.
3.6 V nominal, 4000 mAh high-rate cylindrical lithium-ion cell for 3S1P (10.8 V nominal / 12.6 V max, 4000 mAh) high-speed bill counter and currency sorter packs.
Portable money counters and desktop bill counters use compact internal battery compartments. Measure the maximum internal bay length, width, and thickness in millimeters to allow for outer heat-shrink or ABS housing, end-cap insulation, and BMS protection board clearance.
02
12.6 V Maximum CC/CV Charging Regulation
Standard 3S lithium-ion and lithium-polymer currency counter packs operate with a 10.8 V–11.1 V nominal voltage and a 12.6 V maximum upper charge cutoff (4.20 V per cell). Confirm that the machine's charging circuit regulates to 12.6 V max and does not apply 13.8 V–14.6 V lead-acid or 4S LiFePO4 float voltages.
03
Connector Header Pitch, Polarity & NTC Thermistor
Verify the wire harness length, wire gauge, and PCB header connector type (2-pin power plug or 3-pin plug with 10kΩ NTC temperature sensing) as well as positive (+) and negative (-) pin orientation on the cash counter mainboard.
04
Feed-Roller Motor Inrush & UV/MG/IR Sensor Current
Share your cash counter's continuous wattage (typically 40 W–80 W) and roller motor startup surge current so continuous discharge rating, cell internal resistance (whether polymer, 18650, or 21700), and BMS over-current protection thresholds are matched.

Cash Counter Battery Pack & Cell FAQs
What voltage and capacity battery packs are used in portable money counters and cash counting machines?+
Portable money counters, handheld currency counters, and desktop bill counters typically run on 3S lithium-ion or lithium-polymer battery packs rated at 10.8 V–11.1 V nominal voltage with a 12.6 V maximum charge cutoff, in capacities ranging from 2550 mAh to 5000 mAh (such as our standard 12.6V 4000mAh cash counter battery pack).
Which industry category covers cash counters and currency equipment?+
Cash Counters & Currency Equipment (/industry/consumer-electronics/cash-counters) is organized under 3C & Commercial Electronics (/industry/consumer-electronics) alongside POS terminals, barcode scanners, and commercial handheld instruments.
Can I source both finished battery packs and bare 18650 / 21700 cylindrical cells for currency equipment?+
Yes. Equipment brands and service centers ordering turnkey replacements select our finished 12.6V 4000mAh cash counter battery pack or a custom-harness pack, while pack assemblers can order batch-matched EVE 18650 26V (2550 mAh) or EVE 21700 40P (4000 mAh) cylindrical cells for 3S1P/3S2P assembly.
How does a 12.6 V cash counter battery pack differ from 12.8 V CCTV camera and solar street light packs?+
Cash counter battery packs use a 3S lithium configuration (12.6 V max charge cutoff) for compact indoor currency equipment, whereas our 12.8 V 6Ah–12Ah CCTV camera packs and 12.8 V 12Ah–24Ah solar street light packs use 4S LiFePO4 chemistry (14.6 V charge limit, 10.0 V discharge cutoff). Their chargers must not be interchanged.
How do I confirm battery compartment fit for a portable money counter?+
Provide your currency counter's internal battery bay length, width, and thickness limits in millimeters along with connector pin pitch and polarity. Our engineering team verifies mechanical clearance against our standard 12.6V 4000mAh pack or configures a custom-fit 3S assembly.
What are the delivery lead time and return warranty for cash counter battery packs?+
Standard delivery lead time is 30–60 Days, backed by a 30 days free return warranty and technical support policy. Share your target order quantity and destination country to receive a formal quotation and pack drawing.
Share your portable money counter or desktop bill counter model, battery bay dimensions (L × W × T in mm), 2-pin or 3-pin NTC connector specification, target order quantity, and destination country.
