Q: Can this battery replace a standard lead-acid Group 24?
A: Yes — it’s designed for drop-in replacement, with much greater usable capacity and far lighter weight.
Q: Can I connect multiple batteries for higher voltage or capacity?
A: Absolutely — connect up to 4 in series for a 48 V system, or up to 16 in parallel for up to ~20.5 kWh of storage. :contentReference[oaicite:7]{index=7}
Q: Is it safe to use in cold weather?
A: Yes — the battery has cold-charge cut-off at 0 °C (32 °F) and discharge ratings down to -20 °C, designed for challenging environments. :contentReference[oaicite:8]{index=8}
Q: Does it need maintenance?
A: No watering or acid top-ups. It’s fully maintenance-free thanks to advanced chemistry and BMS protection.
Q: How much weight do I save versus lead-acid?
A: Approximate weight is 21 lb vs traditional 35-50 lb lead-acid of similar capacity—a big win when weight matters (boats, RVs, vans).

Depending on your choice of variant and speed, you can expect between 1.5 hours at wide-open throttle to over 5 hours at trolling speeds. Both options offer exceptional range.
Absolutely. The sea eagle fishskiff completely deflates and rolls up, while the electric outboard motor features a quick-release battery and foldable design, eliminating the need for a trailer.
This varies heavily by country and region. While electric outboard setups often bypass strict gas engine regulations, many locations still require a basic watercraft registration for any motorized sea eagle boat.
Absolutely. The sea eagle boat features a high-pressure 1000 Denier drop-stitch hull that inflates up to 15 psi, making the deck as rock-solid as a rigid fiberglass platform so you can cast with total confidence.
Yes, both the sea eagle fishskiff and the epropulsion motor are fully engineered for harsh marine environments. The motor features high-quality anodized aluminum and powder coating to resist corrosion, though we always recommend a quick freshwater rinse after a salt run.
You can go from a completely packed car trunk to floating on the water in roughly 12 to 15 minutes using an electric pump, completely eliminating the need for boat ramps or storage fees.
Yes! The integrated lithium battery supports on-the-go charging via compatible solar panels, allowing you to seamlessly extend your range on sunny days while running your epropulsion motor.
