Product Description
One-Netbook released the ONEXPLAYER Mini Pro in two distinct hardware generations that share the same battery P/N but are not electrically identical. The Intel Core i7-1195G7 version runs a 3S1P pack: 10455mAh / 40.25Wh at 11.55V, three cells in series. The AMD Ryzen 7 5800U and 6800U versions — the commercially dominant models — use a 3S3P configuration: nine cells total, each rated 4200mAh, delivering 12600mAh / 48.51Wh at 11.55V nominal (13.2V max charge). Both carry the P/N LR386387-3S and use the same connector, which is why the market has conflicting capacity data across listings.
This distinction matters operationally. If you’re sourcing for AMD-variant customers, the 48.51Wh / 12600mAh pack is the correct specification. Intel-variant units take the smaller 40.25Wh version. Ordering the wrong configuration won’t physically damage the device — the connector seats in both — but the BMS will report incorrect charge state, causing early cutoff and customer complaints that look like defective batteries.
The AMD 6800U variant was the high-volume commercial model. At 15W TDP, the 48.51Wh pack delivers approximately 2.5 hours of gaming; at 28W sustained, that drops below 1.5 hours. Units from the 2022 launch cycle are now entering years 3–4 of daily use, which is the window where capacity degradation becomes the leading repair complaint.

Features & Advantages
✅ 🔍 AMD vs Intel — We Clarify What Competitors Don’t
Most LR386387-3S listings show conflicting capacity figures (10455mAh vs 12600mAh) without explaining why. The Intel Mini uses a 3-cell 3S1P pack (40.25Wh); the AMD Mini Pro uses a 9-cell 3S3P pack (48.51Wh, 4200mAh per cell). We supply both configurations clearly labeled, so your repair operation orders the right spec the first time and doesn’t absorb a return cost on a capacity mismatch.
✅ ⚖️ 3S Pack Balance-Tested Before Every Shipment
Series-connected packs have one failure mode parallel packs don’t: cell imbalance. A single weak cell in the string triggers early BMS cutoff and reduces usable capacity across the whole pack. Every LR386387-3S we dispatch is balance-tested — voltage delta across all three series groups verified within spec before the unit leaves production. This step is routinely skipped by re-label suppliers; it’s standard in our process.
✅ 🏭 Factory-Direct, Per-Batch Capacity Verified
We source cells and assemble packs in-house. No intermediary distributors. Wholesale buyers can request batch test records — the AMD version is verified at 12600mAh / 48.51Wh, the Intel version at 10455mAh / 40.25Wh, matching actual label specifications. The 100th unit you receive tests identically to the first.
✅ 🔧 Screw-Secured — Faster Swap Than Adhesive-Bonded Competitors
Unlike the Nintendo Switch Lite which requires IPA adhesive removal, or some sealed handhelds requiring heat gun work, the ONEXPLAYER Mini Pro battery is screwed in place. Standard Phillips driver, back panel off, connector unplug, swap complete. Under 20 minutes per unit for a technician familiar with the teardown. Higher throughput per hour in a repair operation compared to glued-battery devices.
✅ 📦 Tiered Pricing for Recurring Repair Channel Orders
ONEXPLAYER Mini Pro units from the 2022 production cycle are entering years 3–4 of daily use — the natural battery replacement window. Repair demand is widening as the install base ages. Contact our B2B desk with your projected monthly volume for a structured price schedule; we don’t publish fixed wholesale list prices.
✅ ⚙️ 500+ Cycle Rated Life Under IEC 61960 Conditions
Internal cycle testing confirms ≥80% capacity retention at 500 full cycles (1C rate, 25°C ambient). At one to two charge cycles per day, that maps to 18–24 months before noticeable degradation — a predictable reorder cadence for distributors planning inventory around the device’s age profile.

FAQ
Q1: Why do different sellers list conflicting capacities (10455mAh vs 12600mAh) for the LR386387-3S battery?
A: Both are correct — for different hardware variants. The ONEXPLAYER Mini with Intel Core i7-1195G7 uses a 3S1P pack (3 cells): 10455mAh / 40.25Wh. The Mini Pro with AMD Ryzen 7 5800U or 6800U uses a 3S3P pack (9 cells, 4200mAh per cell): 12600mAh / 48.51Wh. Both carry the P/N LR386387-3S and use the same connector, which is why the market has mixed listings. Confirm your device CPU before ordering — check the sticker on the back panel or Windows Device Manager under Processor.
Q2: After installing the LR386387-3S, the ONEXPLAYER Mini Pro shows inaccurate battery percentage. Is this normal?
A: Yes, for the first several cycles. New Li-ion cells require 3–5 full charge/discharge cycles before the BMS calibrates the state-of-charge display accurately. Drain the battery fully, charge to 100%, and repeat. The percentage readout stabilizes as the BMS learns the actual cell capacity. If inaccurate readings persist beyond 5 conditioning cycles, that indicates a genuine BMS communication issue worth investigating.
Q3: What is the realistic gaming runtime on the ONEXPLAYER Mini Pro 6800U with the 48.51Wh battery?
A: At 15W TDP (default performance setting): approximately 2.5 hours. At 28W TDP (maximum supported): under 1.5 hours. Video playback at low TDP (5–8W): 8–10 hours. These figures are consistent with reviewer benchmarks on 6800U hardware. The AMD 6800U power consumption at gaming loads is the primary limiting factor — the 48.51Wh pack is within normal range for a 7-inch Windows handheld.
Q4: Can the Intel version battery (40.25Wh) be used in the AMD version Mini Pro, or vice versa?
A: The connector is physically compatible, but we do not recommend cross-installation. The AMD 6800U BMS is calibrated for the 48.51Wh / 12600mAh spec. Installing the smaller Intel 40.25Wh pack results in incorrect charge percentages and earlier-than-expected cutoff. Always match the battery to the CPU variant of the device being repaired.
Q5: What are your order minimums and lead times for bulk LR386387-3S supply?
A: No fixed MOQ. We supply evaluation sample batches and full production runs. Bulk lead time is 7–15 business days post-confirmation. Sample units typically dispatch within 3–5 business days. For 3S series packs we recommend buyers run a balance-check on received samples — measure individual cell voltages across the string after a full charge cycle before committing to volume.
Q6: What warranty and quality assurance do wholesale accounts receive?
A: 12-month warranty from dispatch date on all wholesale shipments. Every batch undergoes capacity verification and 3S cell balance testing before leaving production. If the DOA rate exceeds the agreed threshold, we issue replacements or credit without a dispute process. Batch test records are provided on request. OEM buyers at qualifying volumes can request custom labeling and compliance documentation for both AMD and Intel variant configurations.
