When connecting a battery is it positive first?
“Positive first, then negative. When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Connect the new battery in the reverse order, positive then negative.”
What does it mean when a battery gets a spark?
If you had your charging system setup and running to the first string–Connecting the second string could give you a spark too. As well as a spark connecting things like AC inverter DC inputs (charging the capacitors). The sparks are good enough to startle me and starts to burn divots into my battery terminals.
Why does my battery charger not spark when plugged in?
Unlike just about every other electrical device: turn the charger on before plugging it in. That way the plug and socket are near the same voltage and you’ll get no spark. It seems like I had my charger turned on (plugged in), then connected the charger barrel connector to the battery and saw a tiny spark. Maybe a tiny one isn’t a big deal.
What causes a spark on an AC inverter?
It is pretty common to get a good size spark when making connections to the AC inverter (and some other DC loads). There are usually capacitors on the DC input of the typical AC inverter. When you make the first connection, these capacitors take a lot of current to charge.

Why do I get a spark when I charge my inverter?
We all know that when you initially connect an inverter to power you get a spark as the capacitors charge up. For bigger inverters this spark is pretty significant. If the final connection is to your battery it means you get a tiny “weld” on the battery terminal each time you do this.

How to avoid sparks when connecting battery to mutlicopter?
-Connect the BTS555 circuit to the power input leads of your power distibution board -Activate the BTS555 circuit by flipping its switch to the ON position. Your mutlicopter receives now full power from the battery and the spark is avoided.
