Pulse Lipo Batteries

Great batteries.
I needed smaller batteries for balance purposes.
These 2250 2 cell 7.4v Rx batteries were perfect.

Perfect fit for Trex 700X

Going to use this to power my Ikon HD FBL. This battery fits perfectly in the right side of the front frame. I'm going to change the EC3 to XT30 since I like the XT30 better.

Great Batteries In A Compact package

I received my batteries as ordered and on time.
I have used Pulse batteries for many years...and have never been disappointed.
Great batteries and great service from Helidirect.
I Will not hesitate to order again!


I have not got my batteries I ordered them on November 26 2020 and today is December 7 2020

Rc pack

Great packs.


These batteries are excellent. Price is very good also.

Product Good, Order Experience AWFUL

Within just a week or so of ordering, I received part of my order. This was unexpected, so I emailed, didn't get a response, and then called and was told this is normal when an item is backordered and I'd receive the rest of my order (all Pulse LiPo's) as soon as stock was available. Numerous times during the MONTHS I had to wait for the rest of my order to arrive, I kept seeing one or more of the items I had paid for showing 'In Stock' on the HeliDirect web site, but no sign of a shipment to me. Finally, I called about this out of pure aggravation and was promised that the In Stock portion of my order would be shipped forthwith. More weeks went by, and I saw that not only was one of the items I paid for showing 'In Stock' again, but another of the items had been discontinued and replaced with a different item than the one I orderd originally that HeliDirect *could* have sent when it was in stock, but sold to someone else instead after verbally promising me that it would be shipped and AFTER I HAD ALREADY PAID FOR IT. Of course, I called and had to ask if I could please have my items, including the one that had been discontinued/replaced shipped to me now that both were in stock. I didn't get a free one, or a discount, or a coupon, or even a sincere apology. I wonder if I'd still be waiting for my batteries if I hadn't called? I don't know where else to get Pulse batteries, so I am not really looking forward to when I may need more of this seriously awesome product.




Very Fast shipping

Great battery

I use 3 of these in a Timber 110. 1 for the ignition and 2 for the Rx. Even with 9 servos I can fly for a couple days and not have to worry about the batteries going dead. The quality is very high and they look really nice too. I did replace the EC3's with xt 60's though.
