Spark and pop.....normal?

[ScarabChris]

When plugging a 6s Lipo into a 180 amp ESC is it normal to get a pop and spark?

mine has a brutal spark with 4s, it gets me every time

Normal... means your caps are still good...lol....Chris the higher the voltage you are running the larger the spark... you should see 12s!! POP!!!! there are ways around the "spark" as it can be hard on the esc's, look around on here and you will find what some do to "pre charge" the caps... heres a good thread to check out

12S2P sounds like a firecracker and over time melts away connectors.

On my 8s setup there is a "spark reducer"(?) that i plug in first that connects the circuit very mildly.......the motor and servo then work, but then you must plug in the bullet to get and amp flow.

and yes, there is a big pop on my 6s setups.

Interesting! I thought there was something wrong. This is the first time I am messing with such high voltage in a "toy". I about crapped myself the first time I plugged it in...LOL.

Lol. It's a sign you are playing with real power now!

Yeah no doubt, now if I can just get the drive hight dialed in and find the right props I can unleash that power.

Yup thats a sign its not totally just a toy anymore :) don't try this at home could be said right after the Connection process... lmao... JK.. just make sure you are thinking straight when you are doing the "hook up" ...... are you running bullets or EC connectors? if bullets be extra careful for obvious reasons...

[ScarabChris]

Yeah 5.5 bullets on everything. I have positives shrink wrapped in red but even then I can see messing up. Especially with a 4 battery pack setup.

I have a "lazy man" spark arrestor method--

I run 2x2S1p (4S1P) config. At first, I just connect a single 2S pack which charges up the capacitors on the ESC (which is why you get the big spark-- the caps suck up the juice), and with just a 2S pack there isn't that much of a spark.

Then I unplug one lead of the 2S pack from the ESC, and hook it to the other 2S pack, then reconnect the newly created 4S1P pack to the ESC-- since the caps are already charged, there is virtually no spark.

I figured this out when I noticed that on my first run, hooking up a 4S1P pack resulted in a big spark, but on my second run with a new pack, the spark was significally diminished-- the caps remain partially charged while changing out the packs!
