I have just bought a BlackJack 26 from ebay. The motor looks like the original <font size="2" face="Verdana"><font size="2" face="Verdana">A3630-1500 Brushless Motor</font></font> but it has been upgraded with an 80A ESC, Octura 442 prop, and red alloy prop supports. There is only one deans connector so I think I can only plug in one battery.

What battery would you suggest is best for overall speed and reasonable endurance?

Also do I need to program the ESC? If so how!?

Thanks for your help as I am new to this so please dont be too technical on replies.

YOU CAN BUY BATTERY AN THE PROGRAM FROM[ WWW.TOWERHOBBIES.COM] THE BHEST BATTERY FROM[WWW.MAXAMP.COM]

You will need a series connector like this

and some Turnigy 25c 5000mah batteries will work great and they are cheap

Thanks, I will get those sorted. How many cells should each battery be?

2 cells

Thank you and this is most helpful. SoI should get two7.2V 5000 mah 25C 2S?
Could I use ones that are a higher voltage 11.1 or 14.4 or would this burn our the ESC or Motor?

this boat is setup to run 4s total
so two 2s packs in series will make for 4s
if you go higher than 4s and I have run 5s in my SV (it flippin ripps!) then you need an rx pack for the esc and disconect the red wire on the esc
but stick with 4s total and have lots of fun with this boat
you could also run two 4s packs in parallel...
like two 4s 4000mah 20c packs that will give longer runtimes and a little better performance

Great Thanks again. I understand how a series connector works by following your earlierlink. What is the difference between series and parrallel and how would I connect the batteries.

Hi,
My new Turnigy batteries have arrived! They are 5000mah, 20C-30C, 4S. I am going to put two of them in parallel in my Blackjack (with upgrade 80amp ESC prop etc). When I go to charge them my charger only goes up to 4A. Does this mean that I wont get the full power out of the battery or that it will just take a long time to charge?

I am also trying to figure out what the numbers on batteries mean.

I know that S means cell and each cell give 3.7V

What does 20-30C discharge mean?

I know that 5000 mah means milliamps but what does this actually mean? Longer runtime? More power?

Thanks
