Fromeco Badger Switch

econpatric

70cc twin V2
So I bought my 71" Slick a new switch and battery pack from Fromeco, and have been very excited to put the pair to work. I do have a couple of questions for those of you using the Badger. Can/should I leave my battery plugged into the switch? I assume this is a "no no" but it seems like it would be fine for a short period of time?

Also I have the 7.4v 2600mah Relion pack. I am curious about what voltage you would re-charge at. I realize that this should be checked under load, but I am just looking for a safe number to look for when I'm out at the field. Thanks! :thumbup:

Patric, you can leave the switch plugged into the battery for a little while. Monthly draw is minimal.

For recharging a relion, I think Fromeco recommends .5C, but allows up to 1C. Don't forget to set the charger to Li-Ion
I let Fromeco know of your questions, and believe they'll reply to this thread.

Really!? So if I charge it to full capacity and leave it plugged in (switch off) I could check it once a month a be fine?

Thanks for the charging info Gary. I am wondering how low - in terms of voltage - is safe for flight. Where would you cut the battery off and recharge?

Hi econpatric, you can leave your Badger switch plugged in for a couple of months. The draw caused by the switch to hold the switch in the off position is very small. I would recommend unplugging them for winter, or if you know there will be a prolonged storage time.

You need to recharge the packs at 7.0VDC under a 1amp load. This should only done with a 1amp load, trying to attempt without a load will most likely end badly at some point.

Hope that helps.

Gyro, good feed back, however we want to ensure people use the Li-PO settings on chargers. I know, I know, confusing. But ensure you use the Lipo setting, 7.4VDC up to 1C charge rate.
2600mA -1C=2.6amps
5200mA -1C=5.2amps

Thanks to all for the information so far, although I think I need to make my question more clear. I did read through the instructions and understand that I need to recharge as you stated in your post.

What I am wondering is what would be the minimal voltage I could fly at without having to use a load checker at this point? I don't plan to fly the pack down to the absolute bottom, is there a safe range for low voltage without putting the battery under load? Eventually I will spring for an '8 Ball' but for now I just need to know what is safe without this check.

It is too dangerous to give you an answer on this. You were clear. However you don't want to do this. A dead Lithium Ion can show a voltage of 7.2. The load check is not really optional, when it comes to measuring for recharge.
The other way to do this is discharge the packs all the way down on a discharger, ensure you have full capacity.
Charge it back up. Then go out and fly 1 normal flight. Record the amount of mA replaced and then fly accordingly.
