For me my motor and vesc have never gone above 60C. The battery never above 30C (this is a 10ah 5s Turnigy battery).
How did your testing go?
It doesnât really matter, 90% of it is for ease of build. Once P group nickel is welded, this is most of the stiffness⌠Youâre just gluing PVC wrappers together⌠If the pack is getting bent to the point that PVC wrappers is what is holding it together, your nickel strip welds are probably already destroyed or will be soonâŚ
Based on experience the final shrink wrap over the whole pack is the main structural component, my flat pack with folded nickel was as bendy as a limp dong before wrapping, currently it holds shape when held by the last cell group (5 cells long)
k thank you got some silicone glue that i will use
Make sure the silicone doesnât smell of vinegar.
You should use a neutral cure silicone.
What if it smells of burnt toast? fa ]sf
Will check what one it is
At what max current do the balancers work at? Like china BMS, DieBieMS or other smart BMS? Anyone know off the top of their head?
edit: To answer my own question. It seems to be < 100ma
Yep @bigben I have the vinegar one
Where can I get half decent proper silicone glue from in U.K.
Also is it worth going hot glue or is silicone better
Hot glue should be fine for your application.
If you want silicone, Screwfix or Toolstation are taking orders online. Look for a neutral cure version.
K thanks
I actually ran out of hot glue and have been to lazy to replenish my glue sticks
Maybe will do that now
Just finished up my printed battery so I thought Iâd post the last few pics here
Stuck it in my street board and took it for a ride yesterday. All seems good.
both melt at least 120+c if your cells get that hot, you have a much bigger problem then loose cells, also your cells are hold with the welds on the nickel, which is way stronger than hot glue / sillicone, they are in place just to hold the cells while welding
how do you like those 3d printed spacers? I guess you donât have many miles with them, but do they hold well?
I am thinking about going with something similar for every future battery I will ever build. No fishpaper between groups and each cell can breathe.
I dint test this partucalar design yet, but I am worry only about this ears
Not my first 3d-printed battery case. The all hold well.
I was thinking more like just spacers, not whole case. To long printing time and unnecessary weight. But your case looks nice!
