Tattu 1800mAh 75C 4S RC lipo battery Testing

I was sent one of the new Tattu 1800mah 75C 4S batteries to do a bit of testing. I’ve been flying it for a week or so and I have spent some time gathering data. Here is what I’ve found so far.

To give a bit of background, I am a multirotor pilot, and am primarily interested in miniquads. That being said the testing I’ve done applies universally. These high C rated batteries are useful beyond the bounds of multirotors into the world of 3D flying, and high performance aircraft.

Physical Characteristics

As with the Gens ace 2200mah I reviewed last month, my first impressions of this RC lipo battery are very positive. Gens ace/Tattu seem to use the same build techniques in both their lower discharge and higher discharge batteries. It has the same aluminum support that covers the battery and adds additional protection to the top and bottom of the battery. After a bit more research I have found that this actually provides compression during high discharge and according to research can significantly extend the life of the battery. Again, where the high current lines enter the battery casing they are re-enforced with additional heat shrink. The balance leads also come out the opposite side of the casing rather than the same side as the high current lines. In addition this battery has a plastic cover that extends over the balance lead cables, preventing stress on the cables when plugging and unplugging the balance cable. I will point out that on some chargers this can prevent the balance leads from fitting properly. Unlike the 2200mah, this battery came with XT60 connectors, which means no soldering for me. Battery dimensions actually exactly the same as the 2200mah 2S battery, and are accurate to the product description on the sellers website. The wight is just over 200g and the physical size is 105mm x 35mm x 25.4mm. Because of the aluminum plates the size is very consistent.

Tattu 1800mAh 75C 4S1P lipo battery pack with XT60 plug

Brand: Tattu
Capacity: 1800mAh
Voltage: 14.8V
Discharge Rate: 75C
Max Burst Discharge Rate: 150C
Configuration: 4S1P
Size: 105mm*35mm*25.4mm
Connector Type: XT-60
Balancer Connector Type: JST-XHR

Features:

1. Stable automatic stacking technology enables single cell capacities of 1800mAh.
2. The most strict single cell capacity, voltage, resistance, discharge curve matching process.
3. Superior Japan and Korea Lithium Polymer raw materials.

Tattu batteries provide high quality, reliable power for LRC Freestyle V1(270-296), CX Pro Quadcopter(228), ortex, Super Mini H Quad Power Train, drone and FPV etc.

Conclusions

My initial impressions of these batteries both in build quality and performance are very positive. Because of the very high C rating, it is hard to get an accurate picture of whether or not this battery can full fill a 75C (135A) current load, but given very few people have a setup that can draw that type of constant load, that’s not something we can easily gauge. Since I haven’t found a reliable method for testing internal resistance It’s hard to get an objective measurement of true C rating. I will post an update as soon as I can test these on a more reliable tester. I can say up to 65A loads this battery performs excellently. I was also very impressed with how well it recovered from first time abuse.

The battery provides both solid performance and the extras in the build such as the reinforced cables and aluminum compression plates add up to a very nice battery. For those interested, the battery is available here:

The use and maintenance of the FPV battery

Now FPV all use Lipo battery, and there are many pilots that they all used 3s/4s battery in the FPV racing competition.

The so-called 3s is composed of three layers lithium cells in series that shows each cell voltage is 3.7 volts, each lithium chip actual voltage is in the range of 2.75 to 4.2 volts. The capacitance marked on lithium is that the energy was getting when 4.2 volts discharge to 2.7 volts. The FPV lithium voltage must be kept at the range of 2.75 volts to 4.2 volts for use. If the battery voltage is lower than 2.75 volts, it is excessive discharge, lithium battery will expand and the chemical liquid will crystallize. The crystallization may pierce the internal structure that cause battery short circuit, even changes voltage charge into zero. The remote model airplane voltage is higher than 4.2 volts, it is overdischarge, the internal chemical reaction is too excessive and the lithium will expand, if voltage keeps charging, the RC lipo battery will expand and burn.

No matter overdischarge or overcharge, both can cause a lot of damages to remote control model airplane battery.

Because FPV battery almost use for violent flight, so must pay attention to the skills about the use and maintenance of FPV battery.

1.The charge voltage should not exceed specified limited voltage (each battery chip is 4.2 volts), 4.25 volts is the highest limitation of each charge voltage. Charge current should not be too large (like the TATTU brand charger of 1500mAh 2 cell lipo battery should be set at 1.5 amperes to 2.5 amperes to charge)

2.Connect battery positive and negative electrodes correctly. If the anode and cathode of battery swap the cell’s poles over will not accept a charge. Reverse charge will make battery damage, cause heating, explosion, leaking and burn.

3.Overdischarge will make battery damage. When the battery discharges, monomer battery voltage should not be less than 3.6 volts (When single cell is 3.8 volts, the plane should almost begin to descend.)

4.The battery should be kept at a cool environment. When store the battery for a long time (over 3 weeks), suggest to put in the environment that temperature keeps at 10 to 25 degree Celsius, low temperature and non-corrosive gas. Battery needs to charge and discharge once three months to keep battery activity, and ensure every chip voltage in the range of 3.7 to 3.9 volts.

5.A good battery should have a good charger. Don’t use no-name charger.

6.FPV must choose the brand batteries, don’t use no-brand-name batteries. Single cell voltage has big difference.

7.When fly in the hot weather, try to choose the moments that before sunrise or after sunset that the temperature is not that high. Pay attention to the heat dissipation of the battery and the electronic speed controller. If can hang the batteries and electronic speed controller outside of the plane, try to dissipate heat outside.

To model airplane pilots:do you really know RC lipo battery?

The batteries is basic of electric model, especially for the model plane. More than 20 years have passed, power battery has a big development,NIMI battery, LIPO battery have also enter the stage of model airplane. Gens ace that has more than 10 years of battery industry to share the RC lipo battery development brief history.

1.what is the power battery

As the engine model by motor is called electric model,and the battery for make the motor work is power battery. They have great different with the other uses of the battery,it is very important for model airplanes’ performance.

2.The type of the power battery and the development profiles

There are many kinds of batteries for using the electric model airplane, such as solar batteries, silver-zinc batteries, lithium batteries, nickel-cadmium batteries, NI-MH batteries and so on. For the solar battery output current is small, so must have done large area to make the electric model plane fly, and cost expensive, thus few takers. Silver-Zinc battery has high specific energy, large current discharge ability is very strong, but the battery lifespan is short, and expensive, easy leakage, don’t fall, so nobody cares. At present, the use popular batteries are nickel serial batteries and new type lithium batteries on model airplane.

In 1970, the electric model plane has became popular in the Europe and United States countries, the mainly due to the NI-cd battery that have strong and repeated charge and discharge has been into practical application promotion and mass production stage at that time. However, in the early 21st century, NI-MH battery performance is better than Ni-cd battery, with it has small memory effect, less pollution to environment, it has been widely used in model aircraft power,became one of the mainstream varieties.

Lithium battery is used as a disposable batteries at early, it doesn’t discharge, and has high specific energy, but it has big internal resistance, therefore unable to provide a big current to make the electric model plane fly. But by the end of last century, we have been able to provide a rechargeable lithium battery, but at that time, lithium battery is more expensive, and the ability of discharge is only barely make the model plane level flight.

At early stage, the study lithium battery is mainly for military, and later in the civil aspect, people gave more attention to its and investment under the huge economic interest. So at the end of 20th century and the early of 21st century has make the breakthrough progress. At present, lithium battery has been used in area such as cellphones, cameras, laptop computers eliminated NI-Cd battery and Ni-Mh battery. The lithium battery used in RC model plane promotion still in recent years. At first, the hobbyist try to use lithium battery of mobile phone put on RC plane to make fly, and obtained the flight time is longer than the NI-Cd battery. Then, it has attracted the battery and model of two industries manufactures. After the lithium battery and model together soon, the lipo battery in the large current discharge ability showed a stronger, more suitable for the aviation model, thus the lipo battery grow into the mainstream variety in RC model aircraft. According to the long term development, model aircraft power battery from now on will be quite a long period of time of RC lipo battery.
