Boost Your eFoil Battery Lifespan with Storage and Slow Charging Modes

Long break coming up? Charging on a boat?
If you think plugging in and forgetting is enough, think again. How and where you charge your eFoil battery plays a big role in long-term performance.

SiFly’s latest firmware (v2.3.940) introduces two powerful features built to protect and extend your eFoil battery lifespan:Storage Charge Mode and Slow Charging Mode. Let's break them down.

💡 Storage Charge Mode: Preserve eFoil Battery Health During Off-Season

Most riders unknowingly shorten their eFoil battery lifespan by leaving it fully charged during downtime. But lithium batteries don’t love sitting at 100%. That’s where Storage Charge Mode comes in.

What it does:
Instead of pushing your battery to full, this smart feature automatically stops charging at around 56V — the sweet spot for safe, long-term storage.
✅ Ideal for off-season or travel downtime
✅ Extends eFoil battery health and lifespan
✅ Keeps your board ready for action, even after months off
Whether you're storing your board for winter or just skipping a few sessions, this feature is your battery’s best friend.

⚡ Slow Charging Mode: Safe Power, Anywhere You Go

Charging at the marina? On a boat with limited outlets or a small generator? No problem.
Slow Charging Mode lets you set a maximum current that matches your power setup — so you can charge safely and steadily without overloading your system.

✅ Prevents overheating in low-power environments
✅ Ideal for boats, RVs, and off-grid spots
✅ Smooth, steady power delivery every time
You’re in control, wherever you plug in.

Update & Ride Smarter

Both Storage Charge Mode and Slow Charging Mode are now live with firmware v2.3.940.

👉 Just update your app, and give your eFoil battery the care it deserves.
Whether you ride daily or only on special weekends, protecting your battery means more ride time, better performance, and fewer replacements down the line.
