The Essential Guide to Electric Assist Battery Care and Management

Electric-assist trikes are a game-changer for many riders, offering enhanced mobility, greater endurance, and an extra boost when needed. However, with great power comes the responsibility of proper battery care. Many first-time users have questions about their batteries' maintenance, storage, and charging—especially in extreme weather conditions. This guide provides authoritative advice on best practices to maximize the performance and longevity of your e-assist trike battery.

Battery Storage and Charging Best Practices

1. Charge Regularly but Wisely

   • If the trike is not in use, ensure the battery is charged at least once a month to prevent deep discharge, which can permanently damage the cells.

   • Ideally, maintain a charge level of around 80% for long-term storage, as keeping a battery at full charge for prolonged periods can degrade its lifespan.

   • According to the U.S. Department of Energy, lithium-ion batteries should be stored at a state of charge between 40-80% to maximize lifespan.

2. Safe Charging Locations

   • Always charge on a non-flammable surface to mitigate the risk of fire.

   • Ensure a smoke detector is nearby.

   • Charge your battery in a well-ventilated area and preferably near an exit in case of overheating or smoke.

   • Never leave a charging battery unattended—avoid charging overnight or when leaving the house.

   • The National Fire Protection Association (NFPA) advises against charging lithium-ion batteries near flammable materials due to potential fire risks.

3. Using a Timer for Charging

   • A simple and safe method uses a charging timer after the battery and motor have cooled down post-ride. This feature is built into Falco chargers. 

   • If your charger does not have this functionality, Set the timer so the charging occurs while you are awake and at home, reducing any risk of unattended overheating.

Temperature Considerations: Cold vs. Hot Weather

1. Cold Weather (Winter Storage and Usage)

   • Avoid leaving batteries in cold temperatures (e.g., a garage during winter). Instead, store the battery indoors at room temperature.

   • Cold weather can reduce charge retention—a fully charged battery left in freezing conditions may have a reduced charge (50% or less) when used.

   • Warm the battery to room temperature before use for optimal performance if riding in the cold.

2. Hot Weather (Summer Heat Management)

   • Avoid leaving your battery in a hot car for extended periods. Even a few hours in a vehicle on a sunny day can cause overheating, potentially reducing battery life and performance.

   • If necessary, a short break (such as a lunch stop) is generally acceptable, but try to park in the shade or cover the battery to reduce heat exposure.

   • Heat affects different battery manufacturers differently, so observe how your particular battery reacts over time.

   • Studies by the National Renewable Energy Laboratory (NREL) indicate that exposure to temperatures above 95°F (35°C) accelerates lithium-ion battery degradation.

Riding Habits That Impact Battery Life

1. Throttle Use and Power Consumption

   • The heavier your thumb on the throttle, the less mileage you’ll get per charge.

   • Try using pedal assist with "Torque and Speed" Sesnor selection on Falco eBike System activated instead of full throttle to extend battery life and range.

2. Preventing Overheating and Component Damage

   • Under high demand (steep hills, high speeds, heavy loads), e-assist systems can overheat. If components feel excessively hot, take a break to let the system cool.

   • A prolonged heavy draw on power can cause wire connectors to overheat and even melt, so be mindful of how aggressively you use assist features.

Battery Security and Key Management

1. Battery Key Management

   • If your battery locks into place with a key, permanently remove the key before riding to prevent it from falling out.

   • Store a spare key in a safe place (garage, glove box, or with your trike accessories) to avoid being locked out of your battery system.

2. On-the-Go Security

   • If leaving your trike unattended, consider removing or locking the battery to prevent theft.

   • Keeping the battery out of direct sunlight or cover for longer breaks will help preserve its longevity.

Final Thoughts: Learning Your Battery’s Quirks

Every e-assist system and battery model is different. While general guidelines apply, real-world experience is the best teacher. Factors such as:

• Manufacturer differences

• Personal riding style

• Local climate conditions

• Individual system quirks

All of these affect how your battery will perform and last over time. Take advice from experienced riders with a grain of salt, as each e-assist setup is unique. The key is to be observant, follow best practices, and adjust your habits accordingly.

By following these best practices, you can maximize the lifespan, safety, and performance of your e-assist trike’s battery, ensuring a smooth and reliable ride for years.
