HRB 2packs 4S Lipo Battery 7200mAh EC5 14.8V 120C Hardcase RC Lipo Battery Compatible with RC Car Airplane Helicopter Truck Boat

Great battery! Much better than the angry snail company I was using.

I'm a retired electronics technician. I have built an electronics bench to design, build and test all things electronic. I also have a high end RC "addiction". I have a need for serious high end Lipo's that can produce lots of power for a long period of time. These are exactly that!. I put these on the test bench and checked them out. Not only were they balanced, but the internal resistance was a bit lower than some of my other Lipo's. You get 7200mah's at 14.8 volts. Technically, these will put out over 7 amps of current for over an hour. That's an amazingly powerful little "brick". Of course you don't ever get that in real life applications. Everything from temperature to how much current you're pulling from them are the most important factors that effect that. I put these on the bench here and the stats showed that they could definitely get close to that. The only way to really tell for sure would be to drain them dead, which would damage them. At $70 a piece, you will want to take care of these. That means STORING them at around 70% capacity, not fully charged, and never let them get down to less than 20% of capacity when using them. It also means that if you have the time, charge them at the lowest charging rate your Lipo charger puts out. So keep them at 80%, then the day you want to use them, top them off and go have fun! I give these five stars and I recommend these if you can afford them.

So far these have been great batteries I haven't had any problems out of them and have used them quite a bit. They have a good runtime about like my other batteries that have the same voltage an mah. I'd definitely recommend these batteries cause the work great and they won't break the bank.

HRB is becoming one of my favorite brands of RC batteries. Especially high performance batteries like this set. These batteries have some of the highest performance features of any RC batteries I have or any of my friends have.These two batteries are configured as 4S1P, which means the batteries have four cells lined in parallel. They come with a whopping 7200mAh of reserved power. That’s a lot of power in one battery. They are also 120C batteries. The C value indicates how safely the energy in a battery can discharge, or leave the battery, to power an RC car for example. This equates to a more powerful and higher performance car. Not all cars can handle 4S batteries so check the ability of your car before trying these out. If not, you may end up with a burned out motor or ESC.This set of 4S batteries are quite large, but that’s how 4S 7200 mAh batteries come. See photos. They come with the EC5 discharge plug, which is the blue plug in my photo. The Balance plug is the smaller white plug in the same photo. I always balance my new batteries before charging or preparing for storage.If nice 4S batteries are what your car needs, then look no further. These are awesome and I highly recommend them.

The media could not be loaded. I can't give these a 5 star because after a balance charge and use the number 3 cell was consistently higher than all the other cells. I'll be honest I have grown to love HRB LIPO packs but when you get a cell like this it kinda makes you question the pack.For those that don't understand LIPO packs, that 1 cell having waymore resistance than the other cells and 1 having way less resistance than the other cells is going to become a problem in the future if you're not continuously balanced charging them.

This is my new go-to brand, without a doubt. I'm so impressed with the consistent and reliable power, with no overheating or charging issues. I utilize an adapter to pair this with a Traxxas Rustler with upgraded motor and this thing will wheelie for days with this battery. So much power and a great capacity for an amazing price. Can't go wrong with this at all!! Highly recommended.

This is my 2nd set of batteries from this brand and I haven't been disappointed yet. These batteries perform well and make a big difference for racing. I put one in my boat and it was a bit much, so I'm going to stick with trucks, but I am very happy with these batteries

This is being used for an electric skateboard... and in series with the 3 cell one of same make and capacity it makes the 7s1p I need but at significantly higher capacity and load than OEM this gives me way way longer ride times and the freshly charged battery punch is there the whole ride.I suspect this will last a long long time but as it's new to me it will.take months to know for sure.
