eFoil batteries store a lot of energy. These basics help you charge, store and handle a lithium-ion battery safely. They do not replace the instructions from your cell, BMS and charger manufacturers. Questions? Email charlie@posterduckcustoms.com.
Charging
- Use a charger made for your battery’s voltage and cell type.
- Charge on a hard surface that will not burn, away from anything flammable.
- Stay nearby while it charges. Do not charge overnight or while you are away.
- Let the battery cool down after a ride before you charge it.
- Do not charge below freezing.
Storage
- If you will not ride for more than a couple of weeks, store the battery at a partial charge, about 40 to 60 percent, not full or empty.
- Keep it somewhere cool and dry, out of direct sun and away from anything flammable. Never leave it in a hot car.
- Check the charge every couple of months and bring it back up to storage level if it has dropped.
Handling and riding
- Check the gasket and seals before every ride. Our enclosures are water resistant, not waterproof, and sealing is up to you.
- Do not drop, crush, puncture or open a battery that is charged.
- After a hard crash or if water got inside, stop using the battery until it has been checked.
Warning signs
Stop using the battery right away and move it outside, away from buildings and anything that can burn, if it:
- Swells, bulges or changes shape
- Gets unusually hot
- Smokes, hisses, leaks or has a strange smell
Only move it if you can do so safely. If a battery catches fire, get everyone away and call 911. Lithium battery fires are hard to put out and can start again after they look finished.
Travel
Airlines strictly limit large lithium batteries, and most eFoil batteries are too big to fly. Check with your airline before you travel.
Disposal
Never put a lithium-ion battery or loose cells in the trash or recycling bin. Take them to a battery recycling drop-off or your county’s household hazardous waste site.
