GNB make batteries with good energy density and price/performance ratio. This LiHV 1850mAh may give a little more top speed when fully charged but voltage sag towards the end of the pack tends to be slightly more than a traditional top quality LiPo.

Difficult to find in retailers right now. This has all the hallmarks of a Halo product made from the very best cells available (similar to a top binned CPU/GPU). Incredible performance but it remains to be seen whether Bonka are able to make lots of these!

These are High Volt packs that charge to 4.35V/cell. They have the best energy density for long flight times and deliver decent burst performance and minimal voltage sag.

DOGCOM are consistently among the highest performing batteries in each size class. This 1850mAh 150C pack has got the juice for multiple high speed runs and fits neatly into the HS5 battery bay.

This pack is at the top of the Ovonic Range. It lives up to it's rating providing enormous power and great energy density. Hard to find right now but a great performing pack.

TheFPV are the house brand of Unmanned Tech in the UK. These batteries have no right being this good for the price.

The Tattu R-Line V5.0 batteries are exceptionally high performing packs. The 1800mAh will fit perfectly in the HS5 and give you great flight time as well as plenty of power for multiple high speed runs in a single pack.

A larger pack with excellent burst performance and good energy density but a little on the heavier side. DOGCOM have good results in my testing so this is another solid option from them.

Where battery performance is critical Tattu R-Line packs have a good reputation for delivering more power at a lighter weight. You pay a little more for the extra performance.
