Re: [PREORDER] Custom GBZ lipo battery pack

I received my shipping notice for two batteries on July 16th and I'm curious what an estimated time-frame should be for East coast, USA orders? I know they have been taking a while, but I'm wondering if anyone else in the US has received theirs yet from the most recent order of extra stock. Thanks! Also, thanks Dex for all the headaches your going through to make sure we all get awesome battery life on our zeros!

To my knowledge it is usually about 5 weeks for East coast but there is no guarantee.
Don't grow up.
It's a trap.

Was about to flip my lid. Pulled out the multi-meter to verify polarity, checked a known good battery, good to go.
Hooked up the new battery, 000.
Hooked up the second battery 000.
Checked known good battery, 000

Oh, one of the leads was just barely sitting in the meter. DOH!

Reconnect 3.99 (both batteries)

Although on one battery they closed it up pinching the wires in two spots, so much love for assembly over there.

Anyway, have it hooked up to a charger and will run it through a discharge cycle later today and will come back to post the measured capacity.
Testing: Kinexsis KX80 draw at 2.0A
Discharge test (done twice before I check the other battery):
Starting Voltage: 4.2V / 4.2V
Ending voltage: 3.11V / 3.01V
Measured capacity: 4128mAh / 4148mAh
76% of rated capacity

2nd Battery
Starting Voltage: 4.2V / 4.2 V
Ending voltage: 3.11V / 3.01
Measured capacity: 3972mAh / 4102 mAh
76% rated capacity

Testing a 2,500 mAh battery I had here and isn't exactly the newest battery.
Starting Voltage: 4.2V
Ending Voltage: 3.01V
Measured capacity: 2113 mAh
85% of rated capacity

And a 4,000 mAh I picked up for my GBZ build and have had in my build and used a few times
Starting Voltage: 4.2V
Ending Voltage: 3.01V
Measured capacity: 4200mAh (always nice to get more than I paid for)
100%+ of rated

So I really hope someone else can do a test and show I just happened to get bad luck on both the batteries I got. Because brand new batteries only giving 75% of rated capacity. Not cool.

And I want to be clear, I am not blaming Dex, not like he's making these things in their garage. Just giving the results I got.

Just ordered 2! Thanks for doing this :)

I actually also have a question. I'm having my orders sent to California (US), and I want to add tracking to the package(s), but noticed there's only standard shipping w/no tracking?

Is there anyway I can add it? Or is standard with no tracking the only option.

Thanks again!
