I looked into it.  The TP batteries are  50% off.  And shipping is free on orders over $200.  However the battery charger I want is not covered by the 50% off.  However right now it is listed at 30% off.  I am looking at the 4 battery charger at $189.  It is listed at $134.  Through in a few batteries at 50% off and you get free shipping!  What a great deal.  I think Santa has found my Christmas gift. 

Thanks for the heads up! Got a couple of 6s 2800’s on the way.

Cobra makes a 2820, and a 3520, but no 3020 that i know if. If it's a bigger plane,  I'm guessing you will be using the 3520.

Well Mrs. Clause has approved my request for a battery charger and batteries.  So I will get:

1 each THUNDER POWER RC QUAD 4 X 100W AC/DC CHARGER (TP4X610HV)
4 each  TP2800-4SPX25

Life is good!   

I have had an order from thunderpower that has been " Pending Fulfillment" for about a week now.  Is that normal for them?  Are they just catching up on assembling batteries after their sale ?Fulfillment

It can take a while for them to get caught up.  I had the same thing happen last year at this time.  If you call they are very nice on the phone.  I pulled the trigger on 8 batteries myself and showing pending fulfillment.
