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.

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:
