14.4V 10Ah IP68 Underwater Scooter Battery Pack — 800–1000W High-Current Thruster Supply | OEM Factory Direct

Q1: The Yamaha Jet Pod Pro OEM battery is rated 14.8V. How do 14.4V and 14.8V relate electrically, and what needs to be confirmed before ordering?

Both ratings describe a 4-cell series Li-ion pack operating across the same charge and discharge voltage window — fully charged at approximately 16.8V, discharge cutoff around 12V. The 14.4V and 14.8V figures reflect different conventions for stating the nominal resting voltage of the same cell configuration: neither figure represents a meaningful electrical difference in operating behavior. What does require confirmation before ordering are the two platform-specific physical parameters: battery bay outer dimensions and connector interface type and pin assignment. These are fixed by the Jet Pod Pro chassis and cannot be assumed from voltage alone. Send us the battery bay drawing or the OEM battery dimensions and connector spec at inquiry stage, and we confirm fit against our tooling before prototype commitment. We can also configure the pack to 14.8V nominal if your platform documentation or downstream certification requires an exact nominal voltage match.

Q2: What is the actual sustained run time at 800–1000W motor load, and how does this compare at different water temperatures?

At 25°C and 50A continuous discharge, the 144Wh pack delivers approximately 12 minutes at 700W average draw, or roughly 8–9 minutes at the 1000W end of the range — figures consistent with the operational profile of large sea scooter platforms where battery swaps are factored into dive planning. At 10°C ambient water temperature, available capacity at the 50A discharge rate typically reduces by 12–18% depending on cell internal resistance at temperature, resulting in proportionally shorter run times. The BMS cutoff calibration on this pack is adjusted for low-temperature voltage depression to minimize premature cutoff, recovering 3–5 minutes of run time compared to a standard 25°C-calibrated BMS in cold-water conditions. For operations at consistent low temperature, specify your typical water temperature at inquiry stage so we can confirm the calibration is appropriate and advise on capacity expectation.

Q3: What is the minimum order quantity, and can the voltage be adjusted to 14.8V to match the Yamaha Jet Pod Pro OEM specification exactly?

Prototype validation orders using existing enclosure tooling proceed at 10 to 20 units. Voltage adjustment to 14.8V nominal is available — this involves a BMS firmware parameter change to align cutoff thresholds with the revised nominal and is standard practice for platform-matched OEM programs. Full customization scope covers voltage, capacity, declared waterproof depth and duration, enclosure outer dimensions, connector type and pin assignment, and BMS communication protocol. Projects requiring new enclosure tooling for a non-standard bay geometry involve a tooling cost and lead time discussion at the proposal stage. Submit your application specification — including platform bay drawing if available — and we return a technical proposal with pricing and lead time within 48 hours.

Q4: How does the enclosure dimensional consistency hold across production batches, and what tolerance is maintained on the critical fit dimensions?

Enclosure critical dimensions — outer housing length, width, height, and O-ring groove depth and width — are held to machined tolerance in the CNC program and verified by first-article inspection with go/no-go gauging at the start of each production run. The inspection record for each run identifies the gauging result and confirms pass before production continues. Any dimension reading outside tolerance stops production and triggers a tooling offset correction before further units are made. This is a production control step, not a visual check — it means that the dimensional consistency you validated on your prototype order is the same consistency maintained through every subsequent replenishment batch.

Q5: What pre-shipment waterproof testing does each unit go through, and how is the 60-meter depth rating verified?

Every unit completes two stages before release. First stage: bench air-pressure integrity test — the sealed enclosure is pressurized to a defined threshold and held for a fixed duration while a gauge monitors for pressure decay. Any unit showing decay outside the pass band is rejected and returned for seal inspection before water contact. Second stage: water immersion at depth equivalent to the declared 60-meter rating, with soak time logged. Both stages generate a record — test pressure value, hold time, immersion depth, soak duration, pass/fail result, and production batch reference. These records are included in the documentation package shipped with OEM orders, providing unit-traceable waterproof test evidence for your product certification and technical file requirements.

Q6: What freight certifications are included, and how do they cover air shipment of a 144Wh battery?

UN38.3 transport certification is included as standard and covers all required testing for lithium battery classification under IATA Dangerous Goods Regulations, IMDG Code for sea freight, and ADR/RID for road and rail transport. For air freight specifically, a 144Wh Li-ion cell pack exceeds the 100Wh per-cell threshold for Section II treatment under IATA PI 965/966/967, meaning shipments require Class 9 dangerous goods documentation and carrier pre-approval — the UN38.3 certificate is the primary document your freight forwarder needs to initiate that process. We provide the certificate and can supply the battery Safety Data Sheet and material declaration documentation required by carriers on request. CE and RoHS certification are available for European market product registration.
