Tattu R-Line V6 hardcore cycle tests
Welcome reader to the most informative commercial pages for LiPo cells for your FPV racing / freestyle drones!
This is our second article in English version! You are here to read how much can you torture your new high Amp discharge LiPo packs for competiton FPV drones – the Tattu R-Line V6.0 packs! Links to other articles from the LiPo.si Academy are in Slovenian language, but then can be translated quite well with Google translate.
Ta prispevek je spisan v angleškem jeziku, saj bodo paketi poželi veliko interesa v tujini. Svetujemo Google translate oziroma povprašajte v komentarjih če vas kaj zanima. Ostali prispevki so v slovenskem jeziku.
When new type of Gens Ace / Tattu battery shows up, we first do initial IR tests to see where they belong. If IR is higher (room temperature), we do some cycles and see how they behave heated up.
But to fully understand how the battery will behave under load and over the lifespan we need to do cycle testing. We started cycle testing long time ago, when we have found out that Gens Ace / Tattu LiPo packs can be charged 10C or above. Most people doubted us, so we proved that fast (field) charging not only saves time, but saves on your expense of owning multiple packs. You need fast charger (with field battery). In most cases two packs are enough. One on the charger, other in the model. When you are done flying, the other battery is already waiting for you fully charged (and heated up). You exchange the packs and off you go. We have proven 30, 40 or even 50 cycles per day are no problem for Gens Ace / Tattu packs!
Before we deep dive into our cycle tests, let us explain some of more common questions:

What is very good to know before reading our testing
We are quite sure that most of the readers will get much of the new information reading these tests. Before we deep dive into this matter we need to clarify few well tested and proven facts of the Genspow made packs.
Tattu Gives You Wins, but you need to know:
We have excellent reputation of giving the best information to our customers. Combine that with the excellent quality of Grepow packs we have almost no RMA. Many customers report 100s of cycles over the years, we even have 13 year old packs with 1000+ cycles still in use (yes, those legendary 25C series!)

Most FPV racers use 1C charge and use dozens of packs.
But with high performance >25C Gens Ace packs it is no problem to charge 5C (already in 2010!), 10C, 20C even 33C for some >95C packs!
Fast charging heats up the pack thus lowering its internal resistance and preparing it for high Amp discharge at higher voltage – i.e. higher power!
No, fast charging at 10C doesn’t hurt performance nor cycle life. No, you won’t blow up your Tattu R-Line packs this way!
Yes, you can slowly charge the pack, but it won’t delivery the same power you will get from heated up (40°C) pack after quick fast charge. However the Tattu engineers are doing extremely good job of creating high discharge packs even at room temperatures. We are so getting used to 10C charging that 1C charge is not only waste of your precious time, but having a dozen batteries is putting a lot of charging work and is not exactly kind to your wallet 🙂
The most important thing is to be sure, that after the charging is complete (which is only 2-5 minutes!) you need to begin discharging the pack as fast as possible. Otherwise fast charging makes no point.

Here is an example of extremely high C rate charging, probably the highest on Youtube as of 2025 😀
Tattu packs handle this with no problem also no problem to get couple of 100 of such charging cycles 🙂 – please see our testing!
For field fast charging we have LFP packs with our chargers for attractive price. Remember we offer full support before and after the buy:
C rating nowadays (and already 15 years ago) is only label number and good for marketing. It can be very misleading for typical consumer.
It is not possible to compare different packs after C rating label. So real tests are needed. Even we have much problems explaining why some Gens Ace packs of only 60C outperform those at 140C!
While some youtube influencers are trying hard to compare packs, they are usually using only 1C charge, which is doesn’t provide good performance for high discharge. External heating of the packs is just too complicated. We recommend fast charging your Tattu packs right before the run.
We suggest temperature of 35 – 40°C before the run. Use fast charging to heat up the pack or if this is not possible at least your own body temperature. Running at below 25°C at high Amp discharge is “hurting performance” of your Tattu packs!
Also please do not overdischarge (disharge at max 90% of the rated capacity!) for good cycle life ( at least 2 years, 300 – 400 cycles).
Yes, we have proven many times, that Tattu LiPo packs can be LiHV charged, i.e. 4,35V or even 4,4V/cell.
The “trick” here is to fast charge the packs (5 to 10C) and immediately (few minutes at most!) discharge them after the charge. This way you will not hurt their performance – test proven!
But you will decrease performance and capacity if you slowly charge them to LiHV (1C) and leave them fully charge for longer than 10 minutes. They will puff badly or even burst if left fully charged at 4.3V/cell for longer periods of time, so beware!
Below is the video of 36C charging Non-HV packs to HV:
Internal resistance numbers can be quite good factor when comparing the current performance of different packs, but they are not everything. When comparing discharge curves we wneed to mention
We measured IR as low as 0.7 mOhm/cell when at 40°C in the first 50 cycles, but can be as high as 2-3mOhm/cell resting at room temperature when >300 cycles old.. Why is this? Well you need low IR when needed for discharge, but for long cycle life you need packs at high IR when storing. V6 R-Line chemistry is really impresive. As soon as some decent load is applied to the pack, the IR drops dramatically if at lower than 25°C temps. But having the pack ready at 40°C it can deliver more power instantly. Nevertheless keep your wires short and your XT60 connectors as clean/new as they can be to extract maximum power!
We have proven that Tattu R-Line V5 150C can do 1000 cycles. Funfly 500 cycles and even then some! How will V6 behave? Lets read on!

First cycles
Our proven “recipe” for long lasting Gens Ace & Tattu LiPo packs is to start quite gentle in the first 5 cycles. We are using proven Junsi iCharger chargers we also sell.
- 5 cycles at 2A charge till 4.1V/cell (Li-Ion) in discharging at ca 2-5C till 3.7V/cell. The photo below is just a sample photo from testing larger capacity pack:

Test equipment
We trust our Junsi iChargers connected via USB cable to a PC running DataExplorer software. We use multiple Quantenergo 100Ah LFP pack as a source and then discharge the tested pack via synchronous regenerative discharging to achieve maximal currents (1 kW , 40-46A ).
How we tested:
- Charging at 16 Amps (10C charge, 4.23V/cell)
- Discharging at 1kW (40-46Amps, first cell to reach 3,65V/cell)
- Initially 50 cycles/day till 290 cycles
- 30 cycles per day from 290 till 500
- Passive cooling only (top+bottom metal cases), no time between cycles
Impressive low IR numbers!
The cells have very low IR numbers up to about 100 cycles.
After 350 cycles
Battery began swelling.
500 cycles done!
- IR around 1.1-1.4 mΩ/cell (new: 0,8 mΩ/cell)
- Max. difference between individual cells: up to 16 mV
- Capacity: 8th cycle 1292 mAh, 500th cycle 1105 mAh (−14.5%)
- Delivered energy: 8th cycle 28.9 Wh, 500th cycle 24.7 Wh (−14,5%)
- Pack swelling: 40 mm new, 45.5 mm at 500th cycle (+14%)
Swollen battery needs more cycles to “come to full capacity”
Interesing observation, which got worst and worst and worst after 300 cycles. Above are cycles from 471 to 500. The battery needed whole 7-8 cycles to come to “full capacity”. Then it the discharged capacity is almost constant which is good indicatior that the pack is not overloaded.
Conclusion
Tattu V6 R-Line 160C are THE BEASTS! Ultra low IR, high energy density, >10C charge (LiHV possible), very high voltage under load… well this is the recipe for the champions! And it is already proven.
LiPo.si proved, that the packs can do 500 cycles under extreme hardcore conditions – 30 to 50 cycles per day on 10C charge (16 A – this is what your Gens Ace D300 does!) and 1kW constant power discharge are no problems at all.
Please keep your wires short and XT60 connectors clean as this will be your main concerns 🙂
At LiPo.si we suggest using fast field charging to keep your battery count to minimum 🙂
