Okay, thanks for the explanation. For our competition, we have to charge while we drive with solar panels and a mppt. Do you know how we can use these batteries while doing that? Our mppt says that we would need bms. Is there a different mppt we should consider?

We think we're going to purchase the RacePow! Does anyone have suggestions for a charger and BMS?

We're leaning toward those batteries too. Thanks for the suggestion v85! A hub motor would be awesome! We've never worked with them before but I am sure they would be great for solar cars. Thank you for giving us Luke's information - we'll definitely reach out to him. :thumb:

Thank you so much for your donation! As first-time users of this forum, we are blown away by everyone's generosity. Your donation will be a big help in purchasing these batteries :D We're still in the early stages of building this year, but so far we plan on having two teams - a first for us...

Thanks for the tips. Here is our website and one of the cars we’ve built in the past. We’re in the process of building new cars this year. https://www.carrollsun.org/ Sorry for the confusion but we’ve always been at the minimum weight and we haven’t added anything to make our car weigh more...

Thanks again for helping us figure this out! For more information, the competition is for the high school SunChase competition at FGCU. Here is the latest version of the rules https://drive.google.com/file/d/1CeO3uGCLfs_WwGJdsU14qeGHmW8nziZl/view?usp=sharing It's included in the document above...

Hey everyone, thanks again for your help. Do you think something like this work too? https://www.batteryspace.com/Tattu-Plus-1.0-44.4V-16000mAh-15C-Smart-Battery-Pack.aspx?gclid=Cj0KCQjwwfiaBhC7ARIsAGvcPe7Ve7YzLYWU1aJCf5Wnt0B6IqAQASFyxaKGYsGilOzqxWFpO-Ge01YaAmA3EALw_wcB Or these? Could do 44.4...

We can charge before the race and then we plan on using just a MPPT throughout the race

Thanks for everyone's help and suggestions! I am excited to share your ideas with my team. Here is a screenshot of the rules regarding batteries.

Hi, my team is in a solar car competition and we need help/suggestions with batteries. We need to go 40mph for as long as possible. What would you suggest for batteries? We can use lithium and the rules say we can have a maximum of 720wh (using the nominal voltage eg 12.8v not 12v) We were...
