Electric hydrofoil battery pack and charger

$25-50 USD / hour

I am making an electric hydrofoil surfboard. It will be powered by 12s4p Basen 26640 batteries. I need to arrange the batteries as 2 packs of 6s4p to use a 6s charger. I need to arrange the batteries in rows of 4, stacked 12 high. Batteries will be mounted inside a carbon fiber vertical mast which is underwater, so battery walls will be touching carbon fiber, with a thermally and electrically conductive epoxy, so they will be cooled by the water on the outside of the mast. I am a mechanical engineer not electrical, and I need detailed schematics and a parts list on what I need to build this, and what design problems I may have created with this idea.

YOU CANNOT CONNECT ANY KIND OF BATTERIES DIRECTLY IN PARALLEL ! You can make 8 packs of 6 in series. Then you can connect 2 of those packs in series to give you 4 packs of 12 in series. Now you will need some high current electronics that will distribute the current equally from the 4 12s packs to your load. Charging will require balancing circuits for each of the 8 packs and 8 separate charging circuits. Regards, Jim

Good day, I have more than 30 years experience in Electric hydrofoil battery pack and charger designing I can develop schematics with a list of components and Electric hydrofoil battery pack and charger designing in a quality and timely manner. Please share me more details about this project. I would like to have a thorough discussion on this project as there are certain suggestions from my side After dedicating more than 30 years to the electronics design and development, I am passionate in designing the best products Technology wise I have worked on all the latest technologies like GSM, 5G, Lora, Electric Hydrofoil Battery Pack, charger etc. And have worked on more than 20 design tools for designing and simulation purpose Some of the generic queries from my side are: 1. What is the application of this product? 2. What will be the ambient temperature of this product? 3. What are the mechanical constraints to be taken care of? If you are someone who wants to benefit from my experience just message me Hi and I shall be there for you. Regards Hari Mohan Engineering for one is magic for others

HI and good morning, I placed the lowest possible fee and it would have been actually lower because I'm really interested in the project since is quite challenging, so even if you don't choose me I could provide some tips: Beware of having batteries in parallel:even with 2 you never get two exactly equal batteries, this means that in the best case one battery will stay undercharged and the other overcharged; moreover if one battery fails two "lanes" will fail, you need basically what is called "BMS" Have an overload/short circuit/over temperature/overcharge protection in place: those things have the bad habit to burn :) ... Have an automatic disconnection of faulty "lanes", so if something goes wrong, albeit having reduced capacity, you still get a working system. Have a visual or wireless checking system that displays the system status, not only the charge but also alarms. If engaged I would need to get the same batteries, motor etc. you plan to use since I do only test real systems: simulations have the tendency of hiding details that come up at the worst possible time. Let me know, if you're interested we can have a chat, if not have good use of my advises. Cheers, Alex.
