Sublue Vapor Battery — Overview
The Sublue Vapor Battery is the removable lithium-ion power pack for the Sublue Vapor underwater scooter. With 13 000 mAh capacity and 384.8 Wh of energy, it delivers up to 60 minutes of continuous diving — long enough for a full scuba or freedive session.
Keep one on the boat as a spare for back-to-back guest dives, or use this listing to replace a worn pack on an existing Vapor. Sublue’s Super-Fast Charging technology refills the battery from 0 % to 85 % in 1 hour and from 85 % to 100 % in 0.5 hours with the Fast Charger.
13 000 mAh · 384.8 Wh
The largest battery in the Sublue diving lineup — 38.4 % larger than typical scuba scooter batteries and the reason the Vapor reaches 10 km/h with 21 kg of thrust.
BMS Multi-Protection
Integrated Battery Management System protects against overcharge, over-discharge, over-current, short-circuit and discharge faults — essential for safe lithium-ion use underwater.
Super-Fast Charging
Fast-Charge to 85 % in 1 hour and to 100 % in 1.5 hours — perfect for charter operators, dive schools and resort fleets running back-to-back guest sessions.
Tool-Free Swap
The battery slides out of the Vapor hull without tools — carry two packs, swap between dives, double your underwater range.

Vapor Battery Use Cases — Spare or Replacement
Two typical use cases for this listing:
- Spare battery — doubles ride time per dive day. Charge one pack on shore while the other is in the water, and swap between dives in under a minute.
- Replacement battery — lithium-ion packs lose capacity over time. Use this listing to replace a worn pack on an existing Vapor and restore full 60 min runtime and 10 km/h top speed.
Who is the Vapor Spare Battery for?
The Vapor battery serves a clearly defined audience:
- Existing Sublue Vapor owners who want a second pack for longer dive days or to replace a worn battery
- Yacht and resort owners who run back-to-back guest dives and need continuous availability without 3-hour charging stops
- Dive schools and rental fleets who keep a rotating set of charged packs in service
- Travelling divers who carry one extra pack for multi-dive day trips
Note: this is only compatible with the Sublue Vapor — not with the Sublue Navbow or Navbow Plus.
FAQ — Compatibility, Charging & Care
Which Sublue scooter is this battery for?
The Vapor battery is compatible only with the Sublue Vapor underwater scooter. The Navbow and Navbow Plus use different battery packs.
How long does the battery last per charge?
Up to 60 minutes of runtime in the Vapor, depending on speed mode, diver weight and water conditions.
How quickly does the battery charge?
With Sublue’s Super-Fast Charger: 0 to 85 % in ~1 hour and 85 to 100 % in ~0.5 hours. The standard charger takes approximately 3 hours from empty.
What protection does the battery have?
The integrated BMS protects against overcharge, over-discharge, over-current, short-circuit and discharge faults — essential safety for lithium-ion underwater use.
Is the battery removable?
Yes — it slides into and out of the Vapor hull without tools.
Can I carry the battery on a plane?
Lithium-ion batteries of this size are typically restricted on commercial flights. Check the airline rules and IATA dangerous-goods regulations before travelling. For yacht and resort use this is rarely an issue.
What is the safe charging temperature?
The battery should be charged at ambient temperatures between 5 °C and 40 °C. Avoid charging in direct sun, in a hot car or in cold (below freezing) conditions.
How heavy is the battery?
The pack weighs 3 kg.
Can I use the battery in salt water?
Yes — the battery is sealed for salt-water use inside the Vapor hull. Rinse the scooter and battery contacts with fresh water after each salt-water dive and let everything dry before storage.
How do I store the battery between trips?
Store lithium-ion packs partially charged (around 40–60 %) in a cool, dry place. Avoid storing at 0 % or 100 % for extended periods to maximise battery life.
How long does a lithium-ion battery typically last before replacement?
Charge cycles, depth of discharge and storage conditions all affect lifespan. Most divers replace packs after 2–3 years of regular use — this listing covers that replacement need.
Can I run the Vapor without a battery?
No — the Vapor is a pure electric scooter and requires the battery to operate.
