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

Great price, charge rate and very punchy.
Will buy again.

Just what I needed !

Great lipo but needs to come with EC5 plug already installed.

Had a hard time finding battery that was the specific size I needed in battery compartment on my RC airplane. Pulse had the exact size I needed.

I love these 1800 packs I use them in my chase 360. Tight fit but it works.fast delivery,Quality Quality Quality can’t say it enough the only battery’s I will ever use

IF you fly 700 size helicopters this is a must have!!!!!, instant power and lots of it!!!,
Excellent fast service from PULSE Battery !

instant power! will buy more,

This Rx Pack is the best. Put a few hours on it and it's still holding 7.5V without charging it yet.

Excellent lipo!! Charges and balances perfectly! Couldn't be happier with Pulse Lipos!.

Great product!! It definitely adds piece of mind while charging. So much I have 3 now. Can't believe I went so long without them. Highly recommended!!. Happy Charging.

I use this size battery in a 4m Eagle (F5J).

These batteries are great so far. They are a little heavier because of the hard case. But when used in series or parallel for larger aircraft they seem to do a great job & the price was great also! Only after long time usage the quality will tell!

Charger works perfect. I have put all my batteries back to storage level. Won’t get a chance to fly again till next spring. The charger has all the features and more for my needs along with a price I could afford.

I like this little charger shop much I have two. The display format & touchscreen make it very easy to use & also monitor battery input, voltage, e.t.c.

Great product, and prompt service

Finally the Pulse Defender arrived here in Germany! Immediately opened the mail pouch and was pleasantly surprised with small size of the unit. Naturally, I had to give it a quick bench test. Attached the lipo to the defender, turned my power on to my heli and plugged the Defender into a vacant slot in my VBar FBL receiver. Located the tiny on/off button on the unit, pressed it once to activate and voila- armed and ready! As indicated in the instructions (online) it started flashing once every 4 seconds indicating all ok! Now the test, unplugged the main power, Defender immediately started rapidly flashing to indicate power failure, and... the FBL still maintained control. This gives you a great feeling to enable a quick landing.
I do have a suggestion, why not enclose the main board in a clear shrink tube that would protect the contacts, electronics from being corroded or shorted out? I would also like the idea of placing the board in a plastic box, e.g. as all receivers are today, and extending the plug in connectors as the VBar does. Maybe eventually available as an upgrade?
One other question, what effect does a 1000 or 1500mA lipo have on the unit instead of a 500mA? Does it still maintain a full charge or would the charge be limited to a 500 capacity? Just a word to others ordering from USA, have patience if the delivery must clear customs; mine took 3 weeks.
