I thought about this solution when I started but a friend told me that having the receiver in a metal box could make problems as it will act as a faraday cage. Fid you try it? Or did you put the receiver in the batteries box instead of the alu one for the esc?
I also use the “everything in one box” solution and so have the esc very close to one battery. And I don’t know if the heat from the esc (even if I have it watercooled) was the reason but I had problems with the battery close to the esc (the voltage was getting low very fast). Now I have put a slice of foam between them to isolate and everything is fine.
Somebody told me that it’s really not good for the batteries to have an important difference in temperature on one side only (warm or cool).

Thanks Jezza…good idea. I also have the batteries secured snugly together with those two white frames. I wonder if that creates a hazard if they swell. This is just my test box for short rides. Eventually I will build the box or boxes into the board.
Yes, that could be a problem, didn’t test it yet. Maybe I need to place the antenna outside. I wouldn’t want to separate ESC and receiver as the receiver gets power from the inbuilt BEC of the ESC.

i would put a 5mm light foam between the battery and a metal plate over the esc

HEllo, What type of foam would you put to insulate the batteries from the ESC? I am looking for some sort of insulating foam with good fire/heat resistant properties.
Thanks

Has anyone found a cheap alternative in France to the expensive Pelican case ? The Seahorse-300 cheaper alternative in the US is three time that price in Amazon France…
That one maybe or is that too small ( 30cm x 23 cm x 13 cm) ? https://www.amazon.fr/TecTake-Etanche-Appareil-Protection-Universel/dp/B07D78R4JY/ref=pd_sbs_421_2/258-4836698-8307608?_encoding=UTF8&pd_rd_i=B07D78R4JY&pd_rd_r=4dac9e2f-7a63-11e9-befd-7173e4d2ac77&pd_rd_w=rPadJ&pd_rd_wg=0iJWM&pf_rd_p=ce0bf35d-908d-4dcb-a083-3a6e21394b79&pf_rd_r=SZVJEQF91RRY3TEBC41M&psc=1&refRID=SZVJEQF91RRY3TEBC41M
I’m going with this case…
Nanuk 910 Waterproof Hard Case… Amazon.ca Something Went Wrong / Quelque chose s'est mal passé
Less expensive than Pelican and decent build quality.
I use the 910 and it’s perfect! I have 120 cells inside, water cooling, ESC, water pump, receiver, and it works great!
In the picture you can see the self circulating water tank. I now use water coming from mast so that gave me more room back. I also added a breaker and voltage meter. Batteries are plastidipped although you can see it’s been coming off.

Are you using a closed water-cooling system? How long can you ride for with that?
Like I said above, I was using a closed water-cooling system but not anymore.
How long did you manage to ride with the closed cooling when you did use it?
I was still in the experimental stage so I never pushed the limits. But judging from how hot the water is being ejected out of the case now I’d say the internal system wouldn’t have been a good long term solution. At least not with the batteries and ESC in the same vicinity. I only used it for a few days while I was waiting on these bulk-head barbs to come in.
Tight fit, nicely packaged. I wondering what your cell setup is, did you manage to fit a row of 12 18650 in the W9.2" width of the case? I looks that you have a 12x5 (2x) cell setup.
- Interior Dimensions L13.2" x W9.2" x H4.1" | Exterior Dimensions L14.3" x W11.1" x H4.7" | Includes a 1 layer cubed foam insert with base pad and lid foam
Yes it’s 12s5p (per pack)
I can also confirm that two of the Turnigy 6s 20ah batteries also fit with tons of room to spare.
Oh I’m sure it’s possible but I’m glad I finally have a proper in-and-out water pump system
Now you make me wonder about having a closed loop inside some aluminium box instead of acrylic box, working as a cooling plate in contact with the outside world…
TCS make a radiator for a closed cooling system. I’m not sure how it would work for our demands though.
