Power your portable printing and scanning fleet with the ASOL 18650-2S4P — a purpose-built 7.4V 8000mAh 59.2Wh Cylindrical Li-ion rechargeable battery pack in a 2-series 4-parallel configuration. Engineered first and foremost for portable thermal printers, this pack delivers the high voltage, massive capacity, and all-day runtime that mobile receipt, label, and ticket printers demand in the field.
Why This Battery?
| Problem | 18650-2S4P Solves It |
|---|---|
| Portable thermal printer dies mid-shift during peak orders? | 8000mAh / 59.2Wh — prints hundreds of receipts/labels on a single charge |
| Single-cell 3.7V can’t power thermal print heads and motors? | 7.4V native output — cleanly drives print head heating elements and paper-feed motors |
| Barcode scanner or industrial PDA runs out before end of shift? | 8-12 hour continuous operation — covers full warehouse and logistics shifts |
| Device needs reliable field power with zero downtime? | 2S4P load-balanced architecture — redundant parallel cells prevent single-point failure |
| Bulk supplier with inconsistent quality for commercial fleets? | ASOL factory-direct — batch traceable, GB 31241-2022 certified cells |

Features
- 7.4V Native Output — Directly drives thermal print head heating elements and paper-feed stepper motors without voltage conversion losses. Clean power rail for MCU + Bluetooth/Wi-Fi module + motor driver on one supply
- 8000mAh All-Day Capacity — 59.2Wh energy reserve means a single charge covers 8-12 hour shifts for printers, scanners, and PDAs. Eliminates mid-shift battery swaps and charging station bottlenecks
- 2S4P Load-Balanced Architecture — Four parallel cell groups share discharge current evenly, reducing per-cell stress and heat buildup. Redundant design means one weak cell won’t kill the pack — critical for business-critical mobile equipment
- Cylindrical Li-ion Construction — Built with 18650 cylindrical cells for stable structure, predictable pack layout, and reliable integration into printer and scanner battery compartments
- Built-in Multi-Layer PCM — Factory-installed protection against overcharge, over-discharge, over-current, short-circuit, and temperature extremes. Safe enough for devices carried and operated by end-users all day
- GB 31241-2022 Certified — Compliant with China’s latest safety standard for portable lithium-ion cells and batteries. Export-ready certification recognized by international buyers
- Customizable Build — Choose connector type (XT30, XT60, JST, Molex, bare leads), wire gauge, packaging, and PCM trip thresholds to match your device’s power input requirements exactly
