eFoil Storage: The Complete Off-Season Guide

When the season winds down and your eFoil is heading into a few months of rest, how you store it decides what condition it's in when you pull it back out of the bag come spring. Moisture, leftover salt, and a battery stored at the wrong charge are the three things that do the most damage to a high-quality eFoil over winter. A handful of clear steps keeps all three in check.

eFoil storage is the process of cleaning, drying, and safely stowing your board, mast, wings, and battery whenever the eFoil sits unused for more than about four weeks. Board, mast, wings, remote, and battery each have their own requirements once they're going into a long rest. This guide walks through every one of them: the final rinse, the right way to dry everything off, and the correct storage charge for the battery. Get these right, and you'll get through any off-season without corrosion, standing damage, or an unpleasant surprise in spring.

Key Takeaways

• Always disassemble and dry before storing: board, mast, and wings come apart completely, get rinsed with fresh water, and are wiped dry with a lint-free cloth before going into the carry bags.
• Store the battery separately from the board: it never belongs in the battery compartment. Keep it somewhere cool and dry, with the red protective caps on.
• Set the storage charge to 30-60%: for storage lasting several weeks, the battery's charge level should sit between 30% and 60%, not full, not empty.
• Check the charge level every four weeks: a battery slowly loses charge even in standby, and a monthly check prevents damaging deep discharge.
• Dryness is non-negotiable: no component, and especially not the battery, should be exposed to direct moisture or condensation during storage.

Why Proper Storage Decides Your eFoil's Lifespan

An eFoil combines carbon, sensitive electronics, and a powerful battery into a device that reacts badly to a long standstill under the wrong conditions. The off-season is exactly the phase where most avoidable damage happens, simply because the eFoil sits unattended for weeks at a time.

Two factors matter most: residual moisture, which attacks metal parts and connectors over time when combined with leftover salt, and a battery that ages faster when it's stored at the wrong charge. Both risks shrink dramatically with the right preparation. On top of that, a simple rule applies: an eFoil that's disassembled and protected in its carry bags during storage won't pick up pressure marks or transport damage either.

We build our eFoils around deliberate corrosion protection and a jet drive fully integrated into the mast, a system with no exposed propeller, built to hold up. That quality only pays off in full if storage plays along. A few minutes of care at the end of the season keep your eFoil flying like day one, season after season.

In short: most storage damage comes from residual moisture and leftover salt, or a battery stored at the wrong charge. Both risks shrink with the right preparation, and a disassembled, dry eFoil in its carry bags stays protected from transport and pressure damage too.

Step 1: Preparing Board, Mast, and Wings for Storage

Before you store your eFoil, take it fully apart. Board, mast, front wing, and stabilizer, along with the remote, get separated so every part dries completely and takes no damage sitting in the carry bags.

Rinse every component thoroughly with fresh water before storing, whether your last session was in fresh or saltwater. Don't forget the drive unit. The jet drive needs a freshwater rinse too. If the board and its components are already clean from the last session, you can skip this step.

When cleaning, one rule matters most: never use harsh or abrasive cleaners like cold cleaners or rim cleaners, and never use compressed air or a pressure washer, both damage paint and seals. A clean, lint-free cloth is the right tool. Use it to wipe the board, mast, wings, the cavities in the battery compartment, and every sealing surface dry.

For long-term storage, dryness is the single most important factor. Pay particular attention to the deck pad and the cavities in the board being completely dry before everything goes into the supplied carry bags. Trapped residual moisture is the most common cause of corrosion over the course of several weeks. Store the bags afterward so nothing rests weight on them, which protects the board and foil from additional pressure marks.

Thorough cleaning after every session, especially after saltwater use, is the foundation of good storage. If you pack your eFoil away clean and dry, you've already taken the most important step toward protecting its value.

Step 2: Storing the Battery Correctly

The battery is the most sensitive component in storage, and the battery storage charge follows an entirely different set of rules than short-term use. Three things matter: separate storage, the right charge level, and absolute dryness. How much care a battery needs over the off-season also depends on its size. Aerofoils offers different battery and charger variants depending on the range you need.

Always store the battery separately from the board, never in the eFoil's battery compartment. Make sure the red protective caps are on the power contacts before you put it away. Clean the contacts themselves only with a dry, clean cloth. If the housing is dirty, a lightly dampened soft cloth helps. A jet of water, compressed air, or a pressure washer are all off-limits.

The most important difference from short-term storage is the storage charge. For storage lasting several weeks, the ideal charge level sits between 30% and 60%. Two lit LEDs after pressing the function button give you a rough indication, that reading is an approximation, not an exact measurement, so check the current manual if you're unsure. A battery stored fully charged or fully drained ages noticeably faster over a long standstill.

Build in a regular check too: ideally inspect the charge level every four weeks and top it up if needed. That avoids damaging deep discharge over the off-season. Store the remote with a partial charge as well, not fully charged. Where it lives depends on the model: the classic handheld controller has its spot in the drive unit bag, while the Hyperbar travels with the board in the board bag.

Battery storage is a topic of its own, from setting the exact storage charge to safe handling. You'll find every detail in our Battery Care and Safety Guide.

A lithium-ion battery also needs a safe storage spot: somewhere fire-resistant and away from easily flammable materials. Never charge or store a battery that's visibly damaged or swollen. Contact Aerofoils service instead.

What does the battery actually need during storage? Separate storage with the red protective caps on, a 30-60% charge, and a check every four weeks to avoid deep discharge. Keep it away from moisture and store it somewhere fire-resistant, away from flammable materials. Never charge a damaged battery.

Where to Store Your eFoil Over the Off-Season

The right storage location matters equally for the board, foil, and battery, though their requirements overlap, the battery is what actually sets the limits in the details.

Choose somewhere cool and dry, protected from damage and unauthorized access, and out of direct sunlight. According to our Battery Care and Safety Guide, the ideal storage temperature for the battery is between 18 and 23 °C at humidity below 65%. Staying in exactly that range slows cell aging the most.

Never store multiple batteries together in a way that lets them short-circuit against each other or any other conductive material, so don't just toss them loose into a box or drawer. And regardless of whether it's short- or long-term storage, no battery should ever be exposed to direct moisture, whether that's rain, snow, or condensation. Condensation tends to form after sharp temperature swings, so let your eFoil and battery acclimate after moving between cold and warm before you pack them away or use them again.

An unheated garage or a damp basement is often unsuitable for exactly this reason. A dry indoor space with stable temperature is the safer choice. For the battery itself, a padded, water-resistant battery backpack gives it a protected spot for the entire storage period. The board is more robust but still benefits from the same dry, frost-free conditions.

Climate matters here too. If you ride at the coast, the air around your storage spot is naturally more humid than it would be further inland, which makes a sealed, climate-stable room more important, not less. A heated basement utility room, a spare closet indoors, or a climate-controlled storage unit all beat an unheated garden shed or a garage that swings between hot afternoons and cold nights. If your only option is a garage, a dehumidifier and a thermometer are a worthwhile investment for the off-season, so you know the conditions your board and battery are actually sitting in, rather than guessing.

The Most Common Storage Mistakes, and How to Avoid Them

Most storage damage traces back to a handful of recurring mistakes, and almost all of them come from skipping a step you'd normally take without thinking twice: the quick rinse, the dry wipe-down, the charge check before you close the garage door for the season. None of them take more than a few minutes on their own. In our experience, the battery charge check is the step that gets skipped most often, simply because the eFoil looks fine sitting in the corner. The problem only shows up months later, as corrosion at a connector or a battery that's aged faster than it should have. Knowing them makes them easy to avoid. The table below summarizes the most critical ones.

Getting Your eFoil Out of Storage: Starting the New Season

A clean off-season storage routine makes the start of the season simple. Still, a quick check before your first session back on the water is worth it.

First, charge the battery fully again and check that the protective caps and contacts are clean and dry. Then look over the mast, wings, and sealing surfaces: anything that spent the winter in storage should be free of moisture, corrosion, or damage. Take a close look at the seals on the battery compartment and the mast, do they sit cleanly and undamaged before you reassemble your eFoil as usual?

If you're taking your board with you right after the off-season, see our eFoil transport guide for the right bags, car loading, and the battery rules that apply on the road. Air travel in particular comes with its own regulations for lithium-ion batteries. Browse our current eFoil models if your season check turns up a component worth upgrading.

Conclusion: Store It Right, Rest Easy

Storing an eFoil correctly isn't rocket science, it's a matter of care: disassemble, rinse with fresh water, wipe dry, and store the battery separately at a 30-60% charge. Follow these steps at the end of the season, and you'll pull an eFoil out of the bag in spring that looks and rides like it did on the last day of the season.
