Battery life is often one of the first things people think about when buying an eFoil. How long can you ride on a single battery, how long does it take to recharge, and will it randomly die and leave you stuck in the middle of the ocean?
These are all fair questions! Often, the advertised range only tells you part of the story. Lift eFoil battery specs vary by setup, and your actual ride time changes depending on factors like rider weight, wing setup, and the amount of power being used, along with the propulsion unit you are on.
Once you’ve read through this guide, you’ll have a better understanding of what each battery’s purpose is, giving you confidence that you’re riding with a reliable setup under your feet.
Key Takeaways
- The Gen5 Full Range battery has a 2.2 kWh capacity and provides up to 90 minutes of powered ride time with LIFT5 and LIFT5 F boards.
- LIFTX uses a smaller 1.0 kWh battery with up to 45 minutes of powered ride time to support its lighter setup and powered/unpowered riding style.
- The LIFTX Light battery is a 0.5 kWh option that is lighter than the 1.0 kWh battery, providing lower swing weight and more maneuverability on the board, albeit with less powered ride time. This setup is ideal for downwinders and experienced foilers who spend a lot of time riding unpowered.
- LIFTX batteries can be used in LIFT5 and LIFT5 F boards when paired with the LIFTX battery adapter. This provides a lighter total weight and optimizes the boards for use with the 55mm prop.
- Batteries should be dry and cool before charging, and used with the correct Lift charger in a dry, ventilated area.
- For long-term storage, we recommend keeping Gen5 and LIFTX batteries at around 30 to 50 percent charge and checking them at least once every 90 days.
- Heat, prolonged low charge, and charging a battery while it is still wet or hot from riding can all affect long-term lithium-ion battery health.
How Long Does an eFoil Battery Last During a Session?
The Gen5 Full Range battery offers up to 90 minutes of powered ride time. The “up to” caveat matters, as battery range can vary noticeably depending on how the eFoil is being ridden. For example, a heavier rider generally asks more from the propulsion unit than a lighter rider. Other factors that can affect range include foil configuration and how much throttle is used. Once you add all of these variables together, two riders using the same battery can leave the water with very different amounts of charge remaining.
Our Full Range battery is a 2.2 kWh platform used with the LIFT5 and LIFT5 F. The 90-minute maximum is useful as a reference point, but it shouldn’t be read as the ride time every rider will get.
LIFTX uses a smaller 1.0 kWh battery with up to 45 minutes of powered ride time. That difference makes sense when you look at how the LIFTX is meant to be ridden (combining powered foiling with periods of unpowered glide). Once you’re riding a wave, wake, or swell, you can let off the throttle entirely, then power back up only when you need it again. The smaller battery is part of a lighter overall setup built for a mix of powered and unpowered riding, but the same range variables still apply as with the Full Range battery. Rider weight, speed, foil setup, and how much time you spend using the motor will all affect how much powered ride time you actually get from a charge.
Battery Size Changes How the eFoil Rides
More battery capacity gives you more stored energy and greater potential range, but the size and weight of the battery also contribute to the overall weight of the eFoil, which can affect performance and maneuverability. This is particularly noticeable with the LIFTX. Its smaller battery is part of what makes the complete setup much lighter and more high-performance than the LIFT5, and suits the powered/unpowered riding style the board is intended for. You still have power when you need it, but don’t have to deal with the weight of the Full Range battery used by the LIFT5 and LIFT5 F.
If you’ve been using or researching our batteries for a while, you may have come across information about the Full Range Battery Gen4 and other earlier battery options. Our battery systems have changed alongside the eFoils themselves, so make sure the capacity, compatibility, and charging information you’re looking at applies to your specific eFoil generation.
How Does eFoil Battery Charging Work?
Charging itself is pretty straightforward. After a session, let the battery dry and cool before you connect it to the charger. Once it is completely dry and cool, charge it in a dry, ventilated area using the correct Lift charger.
A battery that has just finished a hard session can still be warm internally, even if the outside does not feel especially hot. Giving it an hour or so to cool before you connect the charger is part of proper battery care.
Battery charge time depends on the battery and charger you’re using, so check the specifications for your setup. Always use the correct charging equipment instead of adapting chargers, cables, or a data cable from another device.
How Is a Lift eFoil Battery Built?
Our Gen5 batteries are lithium-ion batteries built specifically for the current LIFT5 platform. The battery is fully potted, double-walled, and IP68-rated, which means the internal components are sealed and protected against water ingress during normal use. Gen5 batteries also communicate wirelessly with the eFoil, so there is no external data cable between the battery and board. Once installed, the battery supplies power to the propulsion system while communicating with the rest of the eFoil electronically.
That sealed construction shouldn’t change how you treat the battery after a session. It still needs to be rinsed, dried, cooled, and inspected before charging. We recommend checking the battery and its connections regularly for signs of damage or corrosion.
How Do You Make an eFoil Battery Last Longer?
Battery lifespan has a lot to do with what happens when you are not riding. For Gen5 and LIFTX batteries, we recommend long-term storage at around 30 to 50 percent charge. Store the battery somewhere cool and dry, and check its charge at least once every 90 days.
Do not leave the battery depleted for an extended period of time. During storage, the battery should show two or three out of five LED indicators when tested. If it falls below 30 percent charge, connect it to the charger until it gets back up to around 50 percent. You should also try to avoid heat, especially during charging and storage. Lithium-ion cells age over time, and repeated exposure to high temperatures or extreme states of charge can accelerate that process. That is why charging a hot battery straight after riding or leaving it sitting empty for months is not a good idea.
eFoil Battery FAQs
How much ride time does a Lift eFoil battery provide?
The Gen5 Full Range battery offers up to 90 minutes of powered riding, while the LIFTX 1.0 kWH battery provides up to 45 minutes of powered riding. Actual ride time depends on factors including rider weight, wing setup, throttle use, and propulsion unit configuration.
What is the capacity of the Lift Full Range battery?
The Gen5 Full Range battery is 2.2 kWh and is useful for longer LIFT5 and LIFT5 F sessions with the 68mm propeller.
Should I charge my battery immediately after riding?
No. Let the battery cool first. Also make sure it is dry before charging it with the correct Lift charger in a dry, ventilated area.
How should I store my Lift eFoil battery?
For longer periods of storage, we recommend keeping Gen5 and LIFTX batteries at around 30 to 50 percent charge in a cool, dry place. Check the charge at least once every 90 days. Never leave the battery connected to the charger during long-term storage.
What helps an eFoil battery maintain peak performance?
Avoid excessive heat, let it cool before charging, do not leave the battery fully depleted for long periods of time, and follow our recommended storage range. Those habits help reduce unnecessary stress on the lithium-ion cells.
Understand the Battery Before You Buy the Board
Battery performance makes a lot more sense once you understand the factors that contribute to the maximum range (e.g. “up to 90 minutes”).
A LIFT5 rider looking for a long powered session and a LIFTX rider only using power to get up onto foil before downwinding are asking different things from the batteries under their feet. That is why our eFoil batteries come in different platforms, rather than forcing the same pack into every setup.
If you are comparing boards, start by thinking about the kind of riding you want to do, then consider the battery that supports it.
