When I review niche products like this Tattu R-Line 4s HV LiPo battery, it is very hard to find an exciting introduction. I already rewrote the first sentence three times and still didn’t find something satisfying…

In nutshell, LiHV batteries are like nitro for racing cars. While standard LiPo packs can be charged with up to 4.2V/cell, the Tattu R-Line HV LiPo allows you to charge it up to 4.35V per cell safely. Consequently a standard fully charged 4s LiPo has 16.8V and a HVLi has 17.4V. Furthermore, theoretically, LiHV can store more energy than LiPo per unit of weight.

In addition to the higher voltage, the Tattu 4S1P High Voltage Lipo Battery Pack comes with ultra high discharge rate of 100C.

Tattu R-line 100C, 4S, High Voltage Li-Po battery review

Disclosure: I received this HV LiPo pack as part of a product review collaboration with Gens Ace. Although the battery was offered for free, all opinions in this article remain my own and I was in no way influenced by the partner.

As usual for Gens Ace, battery comes well packed with charging plug protector and safety instruction. At first look, no visual difference between the standard 95C and the HV 100C LiPo pack.

Battery pack measures around 75 x 35.5 x 33 mm (L, W, H) and weights 163 grams. Size and weight is comparable to other LIPOs with same capacity.

Core features and technical specs

• Designed for professional racing drones;
• Higher max voltage than standard LiPo packs (4.35v/cell instead of 4.2/cell);
• Better storage capacity than comparable size packs;
• No memory effect;
• Minimum of 1300 mAh storage capacity;
• 4 cells of 3.8v. Total voltage of 15.2V;
• Ultra high discharge rate of 100C;
• Max Burst discharge Rate: 200C;
• JST-XH charging plug;
• XT60 discharge (drone) plug;
• Net Weight: 163 grams (±20g);
• Dimensions: 75 x 35.5 x 33 mm (L, W, H).

You might wonder to over-charge a normal LiPo to higher voltage like this Tattu 100C HV allows. My suggestion would be DON’T even try it! It would dramatically shorten your LiPo’s life or even cause fire.

If you are using mixed type of LIPOs (normal and HVLi), also keep in mind to always check the charger’s end voltage. It needs to be manually set according to your LIPO battery type. Chargers are unable to detect whether you have plugged in high voltage or regular LiPo.

Tattu High Voltage Li-Po battery review: Test

Prior to my test, I performed a Break-in procedure, which is recommended for new LIPOs. This?consists in 5 gentle charging/discharge cycles.

Recently, I received a QUAD PORT RC charger for review, which is not just compatible with HV LIPOs, but also can charge simultaneously 4 types of battery. I also ordered a thermal probe, which allowed me to monitor the LiHV battery’s temperature during charging/discharging.

As you can see in the comparison table bellow, the HV 100C finished the charging process with higher storing capacity. The end voltage was also higher with 0.6 volt compared to standard LiPo. Both batteries remained?cold (~21 °C) during the charge.

For the real world test, I used my FuriBee GT 215 drone, which can be powered from 4s to 6s LIPOs. Due to the poor weather conditions I managed to have only two short test flight (one with each type of LiPo). Frankly, I found only a slight difference between regular and the LiHV. Performance increase was negligible, at least for me. If you really need higher speed, it is smarter to switch from 4s to 5s (of course if your drone accepts it).

Those who need advantages of a high voltage LiPo battery, this one can be ordered with 15% off from here (delivery from both, US and EU, is available).

Pros

• Higher voltage than regular LiPo;
• 100C, ultra high discharge rate;
• More power on same weight.

Cons

• Needs dedicated charger.

Today we’re going to find out how long it takes to charge the Tattu 4s 1800mah 75c and what the real world flight time is, in comparison to 1300 mAh batteries which are more common for racing drones.

When it comes to racing quadcopters, flight time is not as important as it is in the case of cruising drones. More important is the take-off weight and you need to keep it as low as possible. More weight means less agility and lower speed.

By comparison, the Tattu 4s 1800mah 75c has 193 grams and the Tattu R-Line 4s 1300mAh has only 165 grams. I’m very curious to find out if the extra capacity (500 mAh) will counteract the increased weight.

Review of the Tattu 4s 1800 mAh 75C Li-Po battery

Although I received the Li-Po about a month ago, only now I had the time and mood to review it. You know, battery testing/review is pretty time consuming.

Battery comes well packed with charging plug protector and safety instruction. At first look it seems very well made with good quality terminals.

Battery pack measures around 90 x 33 x 30 mm (L, W, H). Due to the aluminium envelope, the Tattu 1800 mAh weights a bit more than other 4s Li-Po batteries with same capacity. After a bit of research I found out that this producing technique provides not just better heat dissipation and impact resistance, but also compression, in order to minimize puffing during high discharge.

Tattu 4s 1800 mAh 75C battery technical specs

- Suitable for FPV racing drones;
- Minimum of 1800 mAh storage capacity;
- 4 cells of 3.7v. Total voltage of 14.8V;
- Total power of ~ 26.64 Wh;
- Up to 5C charging rate (do not exceed this value!);
- High discharge rate (75C);
- Max Cont Current of 135 A;
- Maximum burst discharge rate of 150C;
- Max Burst Current of 270 A;
- JST-XH charging plug;
- XT60 discharge (drone) plug;
- Net Weight: 198 grams;
- Dimensions: 90.30 x 33.27 x 29.90 mm (L W H).

Battery came about half charged (48%), which is recommended for storing. I measured 15.34V on the XT60 plug. Cell 1 – 3.83V, Cell 2 – 3.845, Cell 3 – 3.83V and Cell 4 – 3.83V.

Is it worth to upgrade from 1300mAh to 1800mAh?

In order to make a fair compassion I used same charger (SkyRC iMAX B6 Mini) with same settings. Both batteries I used for the test had less than 10 charging cycles.

Firstly, I fully discharged both batteries, rest them for 1 hour, then charged them up at 0.5 A. As you can see in the comparison table bellow, the R-Line 95C finished the discharge process more balanced. At the end of charging, both batteries were well balanced. The two batteries remained cold during the charge.

In order to test how these two behave in the real world I used my Kopis 1 racing drone. I tried to fly them with similar amount of throttle in order to get the most accurate results.

As I'm not a Pro racing pilot, I haven't noticed significant performance dropping from 95C to 75C while flying at top speed. Also, the extra weight doesn't seem to be an issue for the 2450KV brush-less motors. Frankly, it's hard to get an objective measurement of true "C" rating without professional tools.

I ended my test flights when OSD shown 14 volts (~ 3.5V/cell). While my flight with the 1300 mAh LiPo lasted about 5 minutes, the one with the Tattu 4s 1800 mah ended after almost 7 minutes. Unfortunately, I forgot home my infrared thermometer and I can’t confirm if motors and ESCs became hotter after the longer flight.

Those who need extra flight time for their FPV racing drone, this Tattu 1800 mAh LiPo can be ordered from EU and USA (delivery from both, EU and US, is available). Now genstattu Black Friday Sale coming soon. Begins 22nd and ends 30st Nov. Don’t miss! More the biggest sale is HERE

Gens Ace and the Tattu brand has a strong reputation in high-performance batteries. Recently, they expanded into speed controllers with the Tattu 30A BLHeli_S ESC, and sent us a set to review.

What's Included

An ESC is a basic component, and often sold in nothing more than a static bag. These Tattu ESCs aim for a higher standard and are supplied in a sleek black box. Inside are the ESCs, of course, as well as a printed manual. This was a nice change from many products we've seen recently that should come with documentation, but don't. You might not think an ESC requires a manual, but it actually provides a lot of useful information on what the startup tones actually mean and what the various settings do.

Electronics

Each ESC appears to be well built with good soldering; components are placed with care and give the ESC a level profile across the top and bottom. Having a level profile prevents extra stress to raised components, which can be especially important in a crash. To connect to the motors, solder pads are provided which can be used from both the top and the bottom of the board. We like solder pads because they're easier to work with than connecting bare wires together and more reliable than bullet connectors. The pads are generously spaced, so accidental bridging is all but impossible. This does leave you with a set of exposed connectors, so it's important to protect them with some kind of sealant, glue, heat shrink, or even electrical tape work fine, if you ever fly in wet conditions. Signal wire and battery leads are soldered on at the factory before shrink wrapping.

Lead wires have silicon insulation and are very generous in length. The power leads appear to be 20-gauge, and the signal wires 26-gauge. The signal wire is wrapped with its own separate ground wire—a plus for electrical noise reduction. It's nice that the power leads are pre-tinned and the signal wire is crimped to a servo header, but on today's tight race builds it's likely that both sets of wires will need trimmed down.

One feature you won't find is a BEC. Many newer builds use a PDB with a regulator included, and many FC boards, cameras, and VTx parts now connect directly to battery voltage. We built these up on a DYS F4 Pro and the BEC would have just added unnecessary weight.

Software

These ESCs run BLHeli_S, which allows easy access to settings through the BLHeli Configurator. According to Tattu, they support regular 1–2ms pulse width input, Oneshot125, Oneshot42, Multshot, DShot150, DShot300 and DShot600; all of which are automatically detected by the ESC at boot.

With Betaflight 3.1, setup is easier than ever. I literally soldered these in without regard for which motor wires should go where. I booted BLHeli Configurator and corrected the motor direction where appropriate. After that, I selected DShot600 in Betaflight Configurator, and then it was props on and ready to fly. There's no need to even calibrate with DShot.

The choice of BLHeli_S is a little curious for what's aiming to be a high-end product. After all, products with BLHeli_32 are already on the market and support DShot1200—a digital communication protocol that finally beats out the best that analog could offer. These Tattu ESCs top out with Multishot or DShot600. After flying them, though, I challenge anyone to tell the difference in a blind test.

Performance

While I couldn't get a 5S on them, I did punch out and fly hard on RaceKraft 5051s on 4S, putting in the best lap times for our informal track day. That's a pretty steep current draw, but the ESCs handled it without issue. After the flight they were a little warm, but nothing concerning. The flight itself was smooth, clean, and responsive at all speeds. In short, these ESCs did their job in every possible way.

Conclusion

There's almost nothing to complain about here: performance, cooling, layout, components, software are all solid. You'll miss out on a BEC and DShot1200, but most builds today have separate voltage regulators and the improvement from DShot600 is largely academic—your system almost certainly has greater lag elsewhere. This kind of no-compromise performance and quality means you'll pay a premium at nearly twice the cost of budget ESCs. Tattu appears to have put a lot of thought and effort into this product, and it shows. We expect the Tattu brand's reputation will carry over from their batteries to these ESCs without any hesitation.
