Optimizing Electric Surfboard Battery Performance with Smart BMS
Designing Custom Batteries for eFoils: A Step-By-Step Guide
The Role of C-Rating in Lithium-Ion Battery Pack DesignEfoil Battery Pack FAQ
What voltage do you recommend for eFoil batteries?
Recommended voltages for eFoil batteries range from 36V to 58.8V. A higher voltage provides more power to your electric surfboard. Please consult with your dedicated CMB advisor to determine the best voltage for your electric surfboard’s battery pack.
How long will a charged CM electric surfboard battery run for before having to be recharged?
A number of factors influence how long a custom battery pack will run for in an electric surfboard, including battery capacity and engine wattage. When designing your electric surfboard, confirm the specifications of your custom battery pack first to ensure enough space is provided in the electric surfboard’s design for optimal battery performance and safety.
What is the timeline for designing and manufacturing a custom battery pack for an electric surfboard?
Every custom battery pack is uniquely designed and manufactured to suit the needs of the specific electric surfboard it will be giving power to. A standard development and production timeline is below for general reference, but times may vary.
Battery pack design confirmation: 7 business days
Prototype production: 15 business days
Prototype shipment: 4-6 business days
Open mold for battery case: 4-5 weeks
Bulk manufacturing: 25-30 business days
Certificates approval: 25-90 business days
What types of Battery Management Systems (BMS) does CM offer for electric surfboard batteries?
Our electric surfboard batteries include BMS’s with overcharge protection, over-discharge protection, and short circuit protection. We also offer Smart BMS options by incorporating UART or CANBUS communication protocols into the BMS design. Smart BMS’s ensure the battery is operating in the safest and most optimal manner, and may also prolong battery life.
What is the Development time for your Electric Surfboard Battery Pack?
Do electric surfboard batteries need to be waterproof?
Whether or not a battery’s casing needs to be waterproof depends on the design of the specific electric surfboard it’s providing power to. Some of our customers do not require a waterproof battery pack because the design of their surfboard is waterproof and ensures the battery’s protection from the elements. That being said, the recommended choice for optimal safety and battery longevity is to go with a battery case design with a waterproof rating of IP68, which CM offers.
How do I obtain the specs for my CMB custom battery pack?
CM Batteries has designed battery packs for the electric surfboard for international efoil company. Once your OEM electric surfboard battery design is completed, your design consultant will release the specific eFoil battery specs to you.
