Mixed lipo brand names work?

[Tony]

Hi guys. I have two brand new lipo batts. One is a Thunder Power lipo 5000mAh 2S1P 7.4V 30C/60 Bust (150A/300A). and the other is a ZIPPY Flightmax 5000mAh 2S1P 7.4V 30C/ 40 Bust. So, can i run these packs together in series, or parallel?

No, different internal resistance. I wouldn't recommend it. One of 'em is probably gonna puff up on you!

Accepted wisdom is DO NOT MIX PACKS!
