4S Battery Testing
Here you'll find a summary of all my 4S battery testing data as well as links to the best performing products in my testing (affiliate policy). Access to the full database of test data is available to my Patreons.
Test Results
Best on Test
GNB 850mAh 120C LiHv
A great performing pack for 4S 3" or 3.5" drones. Energy density, power density and voltage sag are all excellent. The larger 850mAh capacity will extend flight times compared to a typical 650mAh pack but is a little heavier, of course.
TATTU R-Line 750mAh
Tattu packs are expensive but you can't fault the performance. Strong burst performance and good energy density with minimal voltage sag. Similar performance to the 550mAh but scaled up!
Dogcom 560mAh 150C
Excellent performance across the board make this DOGCOM battery an easy recommendation. Energy density, power density and voltage sag all at or close to the top of the charts.
CODDAR 650mAh 120C LiHV
A great performing pack for 4S 3" or 3.5" drones. Energy density, power density and voltage sag are all excellent. Identical to the GNB 650mAh 120C LiHV in terms of weight and performance (likely made on the same production line from the same cells) so buy whichever is cheaper!
TATTU R-Line 550mAh
Tattu packs are expensive but you can't fault the performance. Strong burst performance and good energy density with minimal voltage sag.
GNB 650mAh 120C LiHV
A great performing pack for 4S 3" or 3.5" drones. Energy density, power density and voltage sag are all excellent. Identical to the CODDAR 650mAh 120C LiHV in terms of weight and performance (likely made on the same production line from the same cells) so buy whichever is cheaper!
Dogcom 650mAh 150C
Perfect for a Sub250g AOS 3.5. Excellent performance across the board make this DOGCOM battery an easy recommendation. Great energy density, power density and voltage sag in a slightly larger size!
