Simply add an additional connector in parallel with both your source battery and charger such that both the battery and charger each have two connectors. Add a 5-10 Ohm, 1 watt resistor in series with this second connector. The second connector will be connected first and will limit current while the capacitors charge. After a few seconds, simply plug in your EC5 connector and you're good to go.

I must say that while the one that Mark shows works well, the one that Tyler linked to is pretty compact and simple and chances are, that by the time you buy the resistor, wires and plugs, you may very well have spent the $10 that the Jeti unit costs. I may buy one of the Jeti units the next time I need a spark arrester. I really like the way it looks and works.

Im checking with esprit now on the max voltage. Otherwise the 10 ohm resister sounds very simple.

Thanks guys.

New charger on the way.

Yes, the in-line resistor is simple but it requires another step in connecting. You must connect the resistor plug first and then the main power plug. You must also disconnect both plugs when finished. On the Jeti unit, it is one step. Once you unplug the Jeti plug the power is off. Also, with the in-line resistor, you must make sure that you don't forget to attach the main plug before you start charging or you can burn out the resistor. Not trying to dissuade you, just adding some info.

Esprit says that theoretically there is not a voltage limit on these spark arrestor bullet connections. They do have suggest Amperage limits, and the 5.5mm is rated at 150A. Since the iCharger has a maximum input limit of 65A I believe these will be fine.

Anyone disagree or have a word of caution?

Junsi, How large are the capacitors inside the 4010Duo that must be charged by the spark arrestor capacitors during the connection? Knowing the number and size of the internal iCharger capacitors would better help us determine if the 5.5mm connector is enough. Esprit says they make up to an 8mm connector with more capacitors built in. These larger units can handle 300A, but more importantly they gather and pass through a larger volume of energy to the internal charger capacitors.

These connectors were designed to load the caps in ESC's, but I bet there is more capacity bank inside the iCharger.

The connector is a two part unit. The first thing the bullet touches is a ring that is separated from the female connector by a resistor. As soon as the bullet touches a charge is sent to caps in the charger. It only takes a moment for the caps to charge enough to stop the spark. Once the plug is inserted the rest of the way, the resistor is shorted out and no longer in the circuit. Those 5.5mm plugs will handle way more than you will be drawing with that charger.

Note that the parallel connector can be a very small (and cheap) connector since it carries very little load. JST connectors can be had for pennies. The resistors are pennies as well. An extremely effective parallel spark arrest connector can be assembled for well less than $1.

Seems like this should have been incorporated into the charger

The capacitors inside the 4010Duo are 7*220u/63V.

Have you upgraded to the latest version beta 4?

No. What if it fails?

But what if the attempt bricks the charger?

And what is the rollover function?
