FAQ
-
Is this battery suitable for marine use? Yes. The BPE-U1-1240 features a sealed ABS casing with an IP65 waterproof rating. This makes it highly resistant to splashes, rain, and salt spray, making it an excellent choice for trolling motors, kayaks, and small boats.
-
Do you offer wholesale or bulk pricing? Absolutely. We are the manufacturer and specialize in B2B supply. We offer tiered pricing for bulk orders, distributors, and OEM partners. Please contact our sales team for a custom quote based on your volume.
-
Can I customize the label or brand? Yes, we support OEM/ODM services. If you are a distributor or brand owner, we can customize the battery label, packaging, and even the casing color to match your brand identity (MOQ applies).
-
How waterproof is “IP65”? IP65 means the battery is totally protected against dust ingress and protected against low-pressure water jets from any direction. It is safe for rain and splashes but should not be completely submerged underwater for extended periods.
-
Can I replace my lead-acid battery directly? Yes, this is a “drop-in” replacement. It follows the standard BCI Group U1 size (approx. 198x130x185mm) and uses standard M8 terminals, so it fits perfectly in most existing battery boxes for scooters, mowers, and carts.
-
What is the lead time for large orders? For standard stock items, we ship immediately. For large wholesale or custom OEM orders, production typically takes 15-25 days depending on the quantity. We ensure fast turnaround times direct from the factory.
