Why did by battery go kaput?


#1

Yesterday I finally got my last part and was able to hook up all my parts, but when I did, my spacecell battery would no longer turn on. I’m using 2x 230kv Motors (http://diyelectricskateboard.com/product/electric-skateboard-motor-6355-230kv-2650w/ ) and a dual VESC with the space cell. I can’t imagine what could’ve caused the battery to stop working, as I didn’t even have the remote controller turned on, so I couldn’t have demanded too much energy from the system or anything.


#2

Damn man that’s tough but we’ve all gone thru it. The space cell has a fuse built in I’m pretty sure… Did you check that?


#3

I changed the fuse and tried turning it on without having it plugged into the system and that didn’t change anything.


#4

Does it power on breifly while you still have your finger on the button but then power of when you let go? n other words, does the switch stay clicked in to the ON position or does it just pop back out?

Or is something else going on?


#5

Do you have a multimeter? Is there any voltage coming out of the main terminal? I’m pretty sure your cells are fine those things are bullet proof. Might be a bms or power switch issue


#6

could also be a broken solder joint. I just fixed one of those in my custom multistar pack.

more than likely the space cell issue is the switch.

@mcoyle if you want, contact @onloop and see if he can have you send it to me under a warranty repair. He sent me a whole box of spare parts for fixing these things. I have enough space cell parts to fix just about anything that’s wrong with the exception of the individual cells themselves.


#7

nothing lights up whatsoever when I flip the power switch.


#8

i unfortunately do not, but I wouldn’t expect it to be that either because the problem only began when I plugged it into my VESC


#9

dead BMS or broken solder joint somewhere. IT could still be the switch though depending on how it failed. Sometimes a switch like those will fail to close a connection while still feeling as if its latching properly.

let us know what you decide to do. I’ve got plenty of room on my bench right now.

i just contacted @onloop about how to proceed. I’m just dying to get on my board so I’ll do whatever it takes.

On the Enertion website for the 10s3p Spacecell, it states:

Pack rated to peak output of 60AMP, However incorporates a 40A Fuse for protection, this is ample for use on electric skateboards. This pack is for motors of 2400W or less.
DIY’s 230kv motors are rated@2650 per.
I don’t know why this is or what repercussions there would be to this mismatch, but maybe someone can elaborate for all of us. Very curious.
Hey @onloop, what do ya say, mate?
