I have a Scorpion BUG right now and, with my DS615s, it will brown out if I wiggle the sticks even just a little bit. I'm assuming this will have the same issue?

This looks like a really slick device. I like the self-charging and the auto-arming features, and I was kinda blown away by the fact that there's a mode to discharge it to a storage charge. I'll have to give this a serious look.

Maybe not, as long as your normal voltage is 6V or higher then this one is going to have a little more head-room than the BUG as it arms at a variable voltage, 0.5V below your standard voltage, whereas the BUG is fixed at 5V

The OptiPower Ultra Guard has a continuous current rating of 7A and a peak of 10A. Brown outs are unlikely to be an issue.

Scorpion BUG is also rated for 10A peak, so it seems like a fair question ...

Fair point. Despite being a Scorpion fan, I have never tried or tested their Bug. I have however tested the Ultra Guard with a 7Amp constant load without a problem.

Good point. I run at 6V, which means the UltraGuard would run at 5.5V. A buddy at the field experienced the same issue with his BUG, so I don't think it's a unique issue.

I doubt I'll install the LED. At present, I have a telemetry alarm set up for when receiver voltage drops significantly below 6V, likely meaning the BUG kicked in as a result of losing BEC power and I need to seriously think about landing. I'd use the same setup with the UltraGuard.

I don't think you should be relying on any backup systems if your current radio equipment is browning out your radio gear. I would get a decent RX power source like a Castle BEC or Western Robotics BEC for those power hungry 615's. Then have the Scorpion Bug or Ultra Guard to help out when your primary power source for your BEC fails.

That was testing with only the BUG. I needed to know what it was capable of should my WR SuperBEC fail.

Ah gotcha!

Mine is shipping today!

From pics it looks like the balance port of the lipo connects to the unit. Anyone know which balance tab it supports?

Also anyone know the dimensions of the unit? Shopping around for a lipo for it.

Thanks

It comes with a 430mAh lipo if I'm not mistaken

Just a wild guess but I'd say the same one as is used on this Optipower lipo - Optipower - OPTIPOWER ULTRA Guard 430 Cell only

You can buy the board on its own, but if you don't already have a suitable lipo I have no idea why you would as they are not charging much for the Optipower 430 lipo.
