GensAce batteries have been proven within the Radio Control community to deliver reliable and consistent performance for all modelers alike. All GensAce batteries offer superior cell matching at the factory, and are extremely consistent in selecting matched cells after each and every batch produced. Additionally, low internal resistance (IR), offers modelers stable voltage output through the whole duration of the battery.
Cell Count: 6S
Discharge Rate: 60C
Charge Rate: 2C
Dimensions: 167 x 44 x 45 mm(LxWxH)
Balance Tap: JST-XH
My first impression was that they are really small and light for their size. The 5000mah ones are the same size as Pulse 4500s. I did a couple of conditioning cycles using my Pro Lab 8 and started running them in my Logo 700/Scorpion 4525/Tribunus esc/VTX 717 blades.
On that combination, when I charge, I get cells balanced to within .006 volts and final voltages topping out at 4.185 volts. If I place them on an accurate charge method, I end up with a final charge of 4.198v. When I use them, I have both a timer and a discharge monitor on my ESC that gives me my MAH out. I typically see 2600-2900 mah out and after run voltages from 3.82 per cell with a cell balance of less than .006 between highest and lowest cells. I weighed a Gens Ace and a Thunder Power 5000mah 6s 70c and the Gens Ace weighed 746g complete with EC5 connector, while the Thunder Power weighed 850g with the same connector.
I can't speak with assurance to long term cycle life, but as of now, I find them to be great, and at least equal in power output to my TP, and Pulse packs.
The size and weight factors also compare favorably in their 3300mah packs.
