The SONG L EV has become a staple in the Chinese domestic EV market, and as 2025 models begin rolling out of warranty, independent shops and parts distributors are seeing a predictable spike in TPMS service demand. But here’s the catch: the BYD-built SONG L EV doesn’t use the same sensor across all trim levels and production dates, and a bulk order mistake at the B2B level isn’t a one-unit headache—it’s a 50-unit return, a restocking fee, and a burned relationship with a shop that trusted your inventory.
The BL-ST-096 from BH-Sens (Baolong Technology) is positioned as the go-to 433MHz replacement for this platform. Before you commit to a volume order, though, you need to verify three things that most catalogs won’t tell you upfront.
The 433MHz Assumption and the BYD Platform Shift
BYD has been remarkably consistent with 433MHz across its EV lineup for the past several years, which is good news. The SONG L EV uses the same frequency band as the Han, Tang, and Seal models. But “same frequency” doesn’t mean “same sensor.” The physical mounting design, the valve stem length, and the antenna orientation all differ.
The BL-ST-096 is a clamp-in type sensor, pre-programmed with the OE protocol for BYD. It cross-references to OE part number EUEA3609200B and internal code 110964. If you’re stocking sensors for a full BYD service operation, this one SKU covers 34 vehicle applications—which is a solid inventory consolidation play. But for the SONG L EV specifically, you need to check the production date of the vehicle.
Here’s the practical issue: early 2025 SONG L EV units used a slightly different sensor housing than late-2025 production. The BL-ST-096 covers the 2025+ range, but if you’re ordering for a shop that services 2024 models, you’ll need a different SKU. Always ask for the VIN range before confirming a bulk quote.

What to Verify When Ordering Bulk TPMS Units for SONG L EV
If you’ve been in the aftermarket parts game for more than a few quarters, you know the drill: the catalog says “fits,” but the technician on the other end says “doesn’t sync.” Here’s a checklist that separates a smooth restock from a returns nightmare.
1. Production date, not model year. BYD follows a calendar-year production cycle, but export models and domestic models don’t always align. Confirm the vehicle’s build date (printed on the driver’s side B-pillar sticker) falls within the 2025+ window that the BL-ST-096 supports. If you’re stocking for a shop that inventories by VIN, provide them with the full application list upfront.
2. Pre-programmed vs. cloneable. The BL-ST-096 is pre-programmed, which means it arrives with the correct BYD protocol already loaded. This is ideal for shops that don’t want to invest in a TPMS programming tool. But some fleets prefer cloneable sensors that can mimic the original sensor’s ID for certain diagnostic platforms. If your customer uses Autel or Snap-on TPMS tools, the pre-programmed unit works fine—they just need to trigger a relearn. If they’re using a basic OBD-only tool, confirm the relearn procedure matches the SONG L EV’s requirements.
3. Valve stem torque specs. This sounds trivial, but we’ve seen bulk orders fail because the installation torque wasn’t communicated. The SONG L EV uses a metal valve stem on the BL-ST-096. Overtightening distorts the sealing washer. The spec is 4.5 Nm, not “hand tight plus a quarter.” Include this instruction in your packing slip or product listing to reduce callback rates.
4. Battery lifespan expectations. BH-Sens uses a high-temperature rated lithium battery rated for about 5-6 years of typical driving. If you’re selling to a commercial fleet that runs high annual mileage, the lifespan will compress. That’s not a defect—it’s physics. Just make sure your bulk pricing reflects a reasonable replacement cycle. Some distributors bundle a 10% overstock to cover early failures; that’s a smart move for the SONG L EV given the sensor sits close to the brake rotor heat zone.
The Sourcing Advantage and Why Direct-from-China Matters
When you order BL-ST-096 sensors in volume from longweiparts.com, you’re cutting out the mid-tier distributor markup. Baolong Technology manufactures the OE sensors for BYD, and BH-Sens is their aftermarket brand. This means you’re getting the same production line quality, likely the same silicon, without the dealership parts counter markup.
The practical implication for your shop or distribution business: you can price the SONG L EV TPMS service at a point that undercuts the BYD dealership while still maintaining a healthy margin. At the current market rate, a dealership replacement runs $80-120 per sensor plus labor. The aftermarket equivalent, sourced at bulk rates, lands around half that—and the install time is roughly 20 minutes per corner if the tires are already dismounted.
One word of caution: don’t mix brands on the same vehicle. If the SONG L EV still has three factory Baolong sensors and you replace only one with a different brand, the signal timing can drift, causing intermittent loss warnings. Stick with BH-Sens across all four positions, and you’ll have a uniform transmit interval that the BYD receiver handles without complaint.
The other advantage of committing to a single SKU like the BL-ST-096 is inventory simplicity. One part number covers the SONG L EV, the Seagull, the Dolphin, the Han, the Seal, and a dozen more. You’re not tying up cash in ten different SKUs for BYD models—you’re stocking one box that moves across the entire brand family. For a B2B operation, that’s a significant reduction in carrying cost and a much lower risk of dead stock when a particular model gets a mid-cycle refresh.
Final Recommendation
If you’re sourcing TPMS units for the SONG L EV or any 2025+ BYD EV, the BL-ST-096 is the unit to stock. It’s the same hardware family as the OE sensor, pre-programmed, and covers a wide enough application range that you won’t get stuck with obsolete inventory. Verify the production date, communicate the torque spec to your end customer, and price it competitively against the dealer. That’s the whole game.
