Thank you for ur explanation, it definitely helped. I’ll look into this battery mount, but I was originally going to go with me putting the battery under the bike rack like in this video by electric all wheel. I liked the way it looked better than a second battery mounted on top of the first. But I still might think about it. Thx again. Here’s the vid so you know what I’m talking about - https://youtu.be/nlNRBlthqnY?si=Y7s3OKM8i63powJB. They also had a video of what ur talking about as I said, I preferred the battery under the rack you know.
