@MikeKC good question. I was thinking about that as well. Will probably put a hole through the box and HDPE. I just need to look closer at where I can put it. This battery is VERY snug in the tray and I certainly don’t want to attempt to remove it. Pictured is an empty identical box I bought for fitting.
I’m not super concerned about water collection as the GEM almost never gets wet other than getting washed or hitting a puddle from sprinkler runoff. It rarely rains in San Diego (I’ll drive my regular car on those handful of days), lives in my garage, and my thinking was that even if a little water got in there, it would evaporate in our dry air within a day or two.
That said, I’m worried about road grime and a potential puddle splash on the BMS. I’m guessing the BMS isn’t terribly weather resistant. Wondering how this plexi worked out? 18kwh 225ah Tesla3 Gem battery sold - #6 by Inwo. Are there any concerns about ventilation and heat if I enclose the box?
