I have tried just about every other battery on the market for my 500/600 heli's - these are the best by far.

These are a great battery with only one flaw. Let’s go over the good first:

1250 mah tested, it weighs 212g as advertised.

The bad:

Battery lead could be shorter from factory to save weight (easy fix, cut lead and make it shorter) still deserves 5 stars.

Fast service, came with EC5 connector which wasn't expected, saved me time. Arrived at storage charge, performing as expected.

I think the title says it all.
All around great experience from placing the order to receiving it it great condition.
Pulse batteries are the only choice for my electric and giant scale gas aircraft.
Thank you pulse for a awesome product
Kindest regards

I have always been very satisfied with the quality and service of this product

Love the longer flight time in my trex 470lm

I love the Quality of those bateries, small package, dependable, never a problem with them

Excellent upgrade for my trex 450. After a 6 minute 3D flight, pack is still at 30% and barely warm.

I will say these are great batteries. I use these in my F5J 4 meter sailplanes. With the 450’s I get 1 run of 30 sec or less and 200 meters. If I need it. Early mornings with no thermal activity I use the 450’s as they are the lightest batteries I can safely use to get altitude to make the 10 minute flight. I pull between 37 and 48 amps at full power depnding on the prop setup.

With the active air I switch to the 650 batteries as they give me enough power to search then punch it to get altitude is I don’t see any air worth starting low and climbing to a desirable altitude.

I abuse bot( of these batteries and have nothing but praise. I balanced charge at the end of the day and they are very rarely out of balance. Great quality. I’m a repeat customer and will continue using them for competition

I ordered two of these for a new build. "Moka Gravity 3" with Brother Hobby 1407/4100kV HQ 3x4x3 props.
All I can say is WOW! Point it, Punch it and it's held on going!
Not enough flight cycles to comment on durability but will be getting more.

Pulse makes some of the finest lipo's on the market today. The punch and power they provide in unmatched. There is no other lipo that can compare.

Thanks.

These are high quality, solder-able, shiny plugs that are completely coated in a gold-looking material. They came in a black and red set.
For my requirement of soldering these banana plugs onto the ends of a PSU cable, a 10AWG wire did not fit/insert into its barrel. It measures about 3.14mm I.D. Maybe with some filing down of wire strands. Instead, I opted for a ring type connector.
This banana plug's maximum wire gauge allowed is not mentioned. I tried 14AWG and it fits somewhat loose. I did not have on-hand 12AWG size wire to try.
These plugs are keepers. Some time in the future they will be needed.

My first Graphene purchase. So far I'm getting better flight times than base RDQ line.
Not enough flight cycles to comment on durability, but they seem to be well constructed.

My only disappointment (lol) was no included stickers or strap.

I like the product, good price and fast shipping. Thank you!

I like how light and how well these batteries seem to last. This will be the third plAne I have built using pulse.

Ive ran this battery in my Rc carfor 4 years. This is the only battery I have for it. I also used this battery as a power bank for my isdt charger when I go out flying fpv. Gets me about 3 or 4 1550's recharged very fast. Ive always charged this around 13amps and it just now degraded badly on me. 4 years of heavy heavy use. Really can't beat that. Thanks pulse. Will be buying 2 more very soon

Awesome product! Received my order very quickly, appreciate the great support!

Using it in my Goblin 500. Lots of power.

It’s not my first battery from Pulse, are excellent product and very durable, thanks Pulse Batteries.

Perfect for the JTA Innovations 32-33” Yak, Gamebird and MXS. Getting over 3 min flight times.

My friend introduced me to these batteries. I had to order a couple.

Can’t wait to install on my bird for the back up. Still setting everything up.

I have To pay 53$ extra for shipping in Canada no deal for me

The order was processed as promised, and packaging and delivery was done perfectly!
This is my favorite battery, and this is a product and a brand that I recommend 100%!!

Great value for the dollar. Second purchase same batteries. I like them.

This battery rocks! It only weighs about 250grams according to my digital scale and it makes my timber x an exceptional vertical climber. Very pleased with this battery!

I have used many different batterys looking for this brand I found what I was looking for with the pulse great performance awesome reliability no puff complete confidence in these batteries

I have not tried this device in flight, and hope I never need to. I have tested it by unplugging my receiver battery while Pulse defender was standing by, and it seems like it will work. The switch over seemed instant, and the warning lights (LEDS) are nice and bright. As soon as I plugged my receiver battery back in, the warning lights turned off, and I was back on my receiver battery again. Just keep it unplugged when not in use, as not to drain the small 7.4v lipo. Have it charged fully before use, and long term storage at about 50% charge.

I use two of these 2550 mah 2S batteries for my 120cc Extra 300 to provide power for receiver, servos and ignition. With fully charged, I get about 8 flights with crazy 3D, or about 10 flights IMAC style, and they are still have about 40% left . These batteries are light, reliable, and seems to hold more charges than other brands with the same capacity. They run cool, and they don't puff easily as other brands. I definitely will buy Pulse batteries again.

Order 100% handled with perfection. Batteries arrived as requested. Packaging materials was correct. No delays! Well done!

Battery fits well and works great.

Great Batteries. I put them on my digital scale and show weight is 187g. Lightweight battery for the size! Awesome

Always quality always on time What can I say I mean I keep buying from them and as long as the quality of their shipping is like they say I continue to keep buying from them so far I’ve been impressed not every day you find somebody who knows how to run a business nothing wrong with making a buck back that buck put your money where your mouth is that’s how you keep them coming back do what you say say what you do and I should never be a question about a companies integrity
