Budget 4S Battery Test!

I have been wanting to do this for awhile. A 4S budget battery test.
Our Traxxas X-Maxx, with it's big size and weight puts a heavy load on the batteries. When we first got it, we ran Traxxas batteries - and puffed them quickly!

Over time, we have run multiple brands of batteries in this truck - with varying results. Some batteries will literally puff on the first use depending on how hard we use them during that run!

I was able to pick up 3 sets of budget-minded batteries to test. All cost less than $100 for a pair!
YouMe 6500mah, 60C: https://rover.ebay.com/rover/1/711-53200-19255-0/1?ff3=4&toolid=11800&pub=5575476760&campid=5338469288&mpre=https%3A%2F%2Fwww.ebay.com%2Fitm%2F2pcs-Youme-4S-6500mAh-14-8V-60C-LiPO-Battery-T-plug-for-RC-Drone-Car-Truck%2F362938939783%3Fhash%3Ditem5480d8b987%3Ag%3AvTcAAOSwtjlcyqrj

Ovonic 4S 6500mah, 50C (exact spec not available at this moment): https://rover.ebay.com/rover/1/711-53200-19255-0/1?ff3=4&toolid=11800&pub=5575476760&campid=5338469288&mpre=https%3A%2F%2Fwww.ebay.com%2Fitm%2F2X-OVONIC-6500mAh-14-8V-50C-Lipo-4S-Battery-with-Deans-T-Plug-for-RC-Traxxas%2F183335598797%3Fhash%3Ditem2aafa73acd%3Ag%3AqEwAAOSwwPlc3GLm

Goldbat 5000mah, 50C: https://rover.ebay.com/rover/1/711-53200-19255-0/1?ff3=4&toolid=11800&pub=5575476760&campid=5338469288&mpre=https%3A%2F%2Fwww.ebay.com%2Fitm%2FGOLDBAT-5000mAh-4S-LiPo-Battery-14-8V-50C-Deans-Plug-for-RC-Helicopter-Truck-Car%2F193206904940%3Fhash%3Ditem2cfc07686c%3Ag%3AA~sAAOSwOxZc5Buf

To test these batteries, we did 3 things:
1) a voltage hold test where we charged the batteries and measured how much voltage drop there was over 24hrs.
2) run time and voltage drain test. We ran the batteries as hard as possible to see (a) how long they ran, time, (b) did they puff, and (c) how evenly did all of the cells drain.
3) driving feel - could I, as the driver, tell any difference in power level or performance.

Test 1 starts at 1:20
Test 2 starts at 4:06 for the GoldBat, 7:15 for Ovonic, and 9:08 for YouMe
Test 3 starts at 11:51
Final results are shown at 12:26
