A missing charger is a parts-identification problem before it is a shopping problem. The battery’s name, revision and charging connection all matter. A plug that appears to fit is not evidence that the charger has the electrical specification or charging behavior required by that battery. Resolve the identity before ordering a replacement or trying a borrowed unit.
Two similar listings can mean different parts
Bixpy’s two-pin charger listing identifies PP-333 and PP-378 batteries with a two-pin charging port and says it is not for other battery or power-bank models. Its separate three-pin charger listing addresses outboard batteries with the other charging connection. Both pages tell buyers to check the actual charging port and warn against using an unrelated charger even when the plug fits.
These are examples of manufacturer-specific identification, not a universal pin-count rule. A description such as Bixpy charger, SUP charger or waterproof connector leaves essential questions unanswered. A later battery name or a replacement housing can require fresh confirmation rather than an assumption based on the original purchase year.
Send a useful identification set
While the battery is safely out of use, collect clear photographs of its full label and charging-port identification. If the old charger is available, include its label too. Do not dismantle a connector or open a sealed pack to create this record. Ask the manufacturer which external details it needs if a label is damaged or unclear.
- Record the battery’s complete model and revision, and any externally visible serial or product code.
- Distinguish the charging port from the motor output and auxiliary ports.
- Record the proposed charger’s exact manufacturer part number, not just a reseller’s photograph.
- Ask for written compatibility confirmation linking that charger to that battery version.
Keep the intended power source in the question as well. The mains input information, plug arrangement and local electrical requirements must be checked for the actual charger supplied. A travel plug adapter does not establish that an electrically different charger is suitable. Solar and vehicle charging options, where offered, need their own documented approved configuration rather than a chain of improvised adapters.
Finish the selection before following charging instructions
Once the correct part is established, obtain the matching operating instructions and the manufacturer’s environmental and supervision requirements. A replacement-parts guide cannot safely invent a charging procedure for an unidentified pack. If the battery has visible damage or its condition is uncertain, seek the maker’s advice before choosing a charger as a way to test it.
See the TRIMIX SUP compatibility checklist for the separate board interface. To ask about availability and compatibility, provide the board, fin-box, thruster and adapter models, and identify the battery and charger separately. TRIMIX has no current public SUP-motor listing. Preparing an inquiry does not place an order or establish that a replacement is supplied.
