Everyone's racing into batteries. That's exactly when the corners get cut — and you can't see a skipped test or an old cell from behind a screen.

The Battery Factory Audit App is the on-the-floor checklist a sourcing operator uses to audit a China lithium-battery or energy-storage factory before you pay: cell-maker vs pack-assembler, the UN 38.3 transport file, third-party test reports verified with the issuing body, cell-date-code freshness, the build, the multimeter readings, and the bank-account check. Run it on your iPhone or iPad — offline — score the factory 0–100 with a Proceed / Caution / Walk verdict, and send the report to your boss. One-time $67.

The whole world is running to batteries, and when an industry runs this hot, new factories appear every week — some real, some not, some real but not ready. When everyone is racing to ship, quality is the first thing that quietly slips: a cell that isn't quite what you were promised, a test skipped to save a day, a cheaper part swapped in because the good one was out of stock. You cannot see any of it from behind a screen. And you're about to wire five or six figures to a factory you've only seen in photos.

I audit these factories on the ground. I spend the day on the floor — line by line, meter in hand — for buyers who can't be there. So I put the exact checklist I actually carry into an app. Not a generic form a software company guessed at from an office. The questions I ask, the numbers I meter, the papers I hold, the bank name I check — the discipline that separates a real factory from a story.

• •41 weighted checks across 14 blocks — every question I ask on the floor, scored by how much each one actually matters, so you never miss the one that sinks the order
• •A live 0–100 factory score with a plain-English verdict — Proceed, Caution, or Walk Away — that updates as you tap, so you know exactly where you stand before you leave the building
• •The measurement layer — type your multimeter readings (pack voltage, sensor resistance, isolation to the terminals) straight into the app, and they land in the report as proof, not memory
• •Bilingual 中文 “show-the-manager” cards on 35 items, with pinyin — hold up your phone, the manager reads the exact question in Chinese, no translator and no misunderstanding
• •The excuse layer — on each check, one line on what a factory says to dodge it and what an honest answer actually sounds like, so a smooth “no problem” never fools you
• •Evidence shot-lists + one-tap photo capture — the exact photo to take on each item, saved straight into the report, so your boss sees precisely what you saw
• •One-tap “Send report” to your boss — iMessage, WhatsApp, or email — score, verdict, notes and photos, sent before you walk out the gate
• •Save-as-PDF — a clean, professional report you can attach to a PO, a lender packet, or your own files
• •Runs 100% offline — add it to your Home Screen and it works with zero signal deep inside the plant, and your numbers never leave your phone
• •Audits YOUR order's priorities first — the must-haves from your spec, checked before anything else
• •⚡ 30-minute mode — short on time? It collapses to the highest-weight, deal-breaking checks so you still cover what matters most
• •Pre-visit WeChat questions — what to ask before you ever book the trip, so a dead-end factory disqualifies itself before you fly
• •Optional presence stamp — date, time and GPS location on the report, so there's proof you physically stood in the building
• •A “what remote checking cannot see” list — the app flags what only an in-person visit can catch, so you know exactly where your blind spots are
• •Field-hardened from real audits for demanding Western buyers — see YOUR exact model actually on the line, inspect aged / returned packs for swelling and corrosion, measure the pack dimensions, pin honest capacity + a dated schedule, and get the specs in writing
• •One-time $67. No subscription. Own it and run it on every battery supplier you visit, for years

Want my eyes on it? The Desk Review.

The app gives you the score and the evidence. Sometimes you want a human read on top of it — from someone who's seen a thousand of these. So run the audit, generate your report, and send it to me.

I give you my written assessment — the judgment and the tells I don't put in any app, on your exact supplier — within 2 business days. No call, just the read. That's the Desk Review, $97, and it lives one tap away inside the app.

• ▸My written go / no-go on your scored report
• ▸The tells that only come from being on the floor for 25 years
• ▸Delivered in 2 business days — no call to schedule

Importers, procurement leads, and sourcing agents buying lithium batteries, packs, or energy-storage from China — whether you're flying to the factory yourself or you're already on the ground and want the operator's checklist in your pocket.

"I'll just make my own checklist." You can — and most people do, badly, leaving out the exact lines that cost them: the UN 38.3 report that decides whether it can even ship, the cell maker named on the certificate, the multimeter readings, the bank-name check that stops the most common fraud in this trade. This is the one I actually carry onto the floor, already built and structured the way an operator prices risk, for less than a rounding error on your order.

Built by Cengiz Gündüz — 25 years in cross-border trade, on the ground in Shanghai, inside these factories every single week. He sells industrial goods out of China himself, so there is no supplier to push and no kickback. This is the checklist he runs on his own money, handed to you.

One bad battery order — a cell that fails in the cold, a shipment that can't fly because there's no UN 38.3 file, a wire to the wrong account — costs you five or six figures. This is $67, one time, and you run it on every supplier you ever visit. Cheap insurance on an expensive mistake.

The "Don't Get Burned" Guarantee

Use it on your next order. If it doesn't save you a headache — or a dollar — email me within 7 days and I'll refund you in full. No forms, no hoops. I'm one operator in Shanghai, and I answer every email myself. — Cengiz
