BYD has sold this compact EV with different battery and motor packages across markets, while later Atto 2 EV offers add larger-battery choices. The version name alone is not enough. Link battery capacity, motor output, charge hardware and software to one production record. The useful outcome is a documented decision that another person can review, not a confident-sounding conclusion detached from the vehicle.
Short answer
Link battery capacity, motor output, charge hardware and software to one production record. State the battery identity in the sales file and retain a photo or diagnostic record that supports it.
Assuming the newest export-market Atto 2 specification applies to an earlier China-market Yuan Up creates a false quotation. Instead, rank confirmed facts, seller-stated claims and open items separately so price comparison does not hide technical uncertainty.
01Decode the China-market trim+
Begin by fixing the evidence boundary. Decode the China-market trim. For this identify decision, retain the source, date, VIN or candidate reference and the conditions under which the observation was made. Seller wording should remain distinguishable from independently observed evidence.
Link battery capacity, motor output, charge hardware and software to one production record. If the evidence conflicts, pause the comparison and request a clearer record rather than averaging incompatible claims. This matters because state the battery identity in the sales file and retain a photo or diagnostic record that supports it.
02Check export-market Active, Boost or Comfort naming+
Next, compare the record with the physical vehicle. Check export-market Active, Boost or Comfort naming. For this identify decision, retain the source, date, VIN or candidate reference and the conditions under which the observation was made. Seller wording should remain distinguishable from independently observed evidence.
Link battery capacity, motor output, charge hardware and software to one production record. If the evidence conflicts, pause the comparison and request a clearer record rather than averaging incompatible claims. This matters because state the battery identity in the sales file and retain a photo or diagnostic record that supports it.
03Separate usable range from battery capacity+
Treat uncertainty as a line item, not a reason to guess. Separate usable range from battery capacity. For this identify decision, retain the source, date, VIN or candidate reference and the conditions under which the observation was made. Seller wording should remain distinguishable from independently observed evidence.
Link battery capacity, motor output, charge hardware and software to one production record. If the evidence conflicts, pause the comparison and request a clearer record rather than averaging incompatible claims. This matters because state the battery identity in the sales file and retain a photo or diagnostic record that supports it.
04Verify AC and DC hardware+
Test the result against the buyer's actual daily use. Verify AC and DC hardware. For this identify decision, retain the source, date, VIN or candidate reference and the conditions under which the observation was made. Seller wording should remain distinguishable from independently observed evidence.
Link battery capacity, motor output, charge hardware and software to one production record. If the evidence conflicts, pause the comparison and request a clearer record rather than averaging incompatible claims. This matters because state the battery identity in the sales file and retain a photo or diagnostic record that supports it.
05Record production-date changes+
Close this check before the commercial file moves forward. Record production-date changes. For this identify decision, retain the source, date, VIN or candidate reference and the conditions under which the observation was made. Seller wording should remain distinguishable from independently observed evidence.
Link battery capacity, motor output, charge hardware and software to one production record. If the evidence conflicts, pause the comparison and request a clearer record rather than averaging incompatible claims. This matters because state the battery identity in the sales file and retain a photo or diagnostic record that supports it.
Primary reference points
Official material is a starting reference, not a substitute for candidate verification.
Close the file with visible open items.
State the battery identity in the sales file and retain a photo or diagnostic record that supports it. Record who will resolve every outstanding item and whether it affects purchase, shipping, arrival or later ownership. A replacement candidate receives a new review even when the colour and advertised trim are identical.

Buyer questions
What should be confirmed first for How Do Yuan Up and Atto 2 Battery Versions Differ?+
Link battery capacity, motor output, charge hardware and software to one production record. The answer must remain tied to one VIN, market version and destination rather than a generic listing.
Can a seller statement replace inspection evidence?+
No. A seller statement can identify a claim, but condition, charging and installed equipment should be supported by dated records or direct observation where practical.
Does this guide guarantee destination registration?+
No. State the battery identity in the sales file and retain a photo or diagnostic record that supports it. Current customs, tax, registration and electrical requirements must be confirmed with competent destination advisers.
