I have not found anything like this, so here is my problem. I have 2 6S 3700mAh zippy lipo packs. I want to discharge them in parallel. For the charging i want a simple solution to charge them individually. I don’t want to parallel charge the packs as it is not really recommended. (BMS is not a option, as i don’t have the space) So now i either have to open up the enclosure and get them out of it, or i try something like this. The idea is that i can control wich pack i’m charging with the switches. It wont arc because there is no power running when the loop key is removed. I know that i need big siwtches but thats okay. i got some.
Anyone got any idea’s? I still have to make my enclosure. I want to keep it stealthy so no food storage container for me If i make an enclosure that is easy to open, the problem is solved as well. Still have not found anything useful. I do have access to a 3d printer (ultimaker 2 and 3) so if anyone has a enclosure that i cant print and is easy to open, please let me know.
If it is save to parallel charge, why and how does it work exactly? i’m really skeptic about it because the charger has to balance 2 packs at the same time.
Thanks in advance
I found some motivation and dedicated my entire day to designing an enclosure that is printable on most printers. Here are some screen caps as a proof of concept. Screencaps
If this is fully designed and tested i will upload the files and make a new thread in the mechanical sub.
For the mounting of the 2 shell parts i will just use glue or epoxy. For the baseplate i will mount an aluminium plate to the bottom. This prevents the plastic getting damaged by the little rocks that smash against it while riding. I’m not sure how i will mount it, but i will come up with something.
The baseplate is removable from the shell using M5 Thumbscrews on 6 location along the structure. inside the shell are hexagon holes big enough to press fit a m5 Lock Nut in. this will ensure that the thumbscrews won’t come lose while riding. i left the front flat so if anyone that wants to add a screen is able to do so.
rough dimensions : Height 55mm , length 370, width 170. Everything is at least 5mm thick to ensure stiffness,
let me know what you think or how this may be improved!
