This is the latest generation of Thunder Power RC, and I think we know this battery already. This battery does not only look like the AMAX inno 1550, it does also perform surprisingly equal.
First the nice feature I would like to see more like on the Thunder Power Adrenalin 1300mAh. This battery has also a very short balance lead, and a small flap made out of the same heat shrink the battery is protected with. So, while flying, the balance lead is always out of the way and can not be damaged. Nice! Come on, I want this feature on more batterys!
This Lipo has quite an unusual form factor. While most of the competitors have a width of around 34-35mm, Thunder Power RC did (like the AMAX) make the pack really wide. This Lipo has a width of 45mm. So check your Quad if this Lipo will fit.
Here are some batteries for comparison (L x W x H):
73mm x 45mm x 30mm (Amax inno 90C 1550mAh)
85mm x 34mm x 33mm (Infinity Race Spec 90C 1500mAh)
75mm x 35mm x 39mm (Tattu R-Line 2.0 HV 1550mAh)
The 176g weight is also interesting, because this is even lighter than the AMAX with the same form. This is because of the shorter cables. The temperature is higher than for example the Infinity or Tattu V2, but this seems to be a effect of the form factor with this wide but smaller height of the pack. This pack will also be monitored how it will perform over time, because of this form factor.
The difference to the AMAX seems to me to be the current production fluctuation at the manufacturer of the lipos.
