Appearance

The new Dinogy Platinum Graphene 2.0 V2.0 batteries are delivered in a small cardboard box with the usual Dinogy design printed on the outside. Inside you find the battery packed in bubble wrap for safe transport. All the important technical data (charge voltage, cut-off voltage, etc) are printed on the back of the pack. That is something we have commended Dinogy* on again and again. If you are flying different battery brands it is vital to have all the important info about your battery where your battery is (and not on some small sheet of paper back home).

Dinogy Platinum Graphene 2.0 4S 1850 mAh 130 C V2.0 - Box
Dinogy Platinum Graphene 2.0 4S 1850 mAh 130 C V2.0 - Bubble Wrap

The new Dinogy Platinum Graphene 2.0 V2.0 packs are the first batteries from Dinogy receiving a 130 C rating. The V2.0 of the Platinum series now has a white shrink wrapping. The red honeycomb-style plates on the sides still is here. The pack also claims to squeeze in 50 mAh bonus capacity compared to other 1800 mAh batteries.

The overall built-quality is very good – nothing to worry about. The complete 4S line up only differs in width regarding the total dimensions as you can see in the picture below.

Technical Design

The Dinogy Platinum Graphene 2.0 1850 mAh 130 C V2.0 battery is a standard 4S1P config flight pack for high power use. It utilises the newest generation of Graphene 2.0 cell chemistry. Charge rates up to 3C enable you to fill the pack up quick, if you ever have the need to. We still favour to stick with 1C charging for our tests.

Build Quality: Very good. The pack feels very well made on the outside. Connection terminal looks solid. The white shrink wrap is really tight. There should be no puffing. It looks like there is a spacer between cell 2 and 3 to allow better ventilation.

Plugs: The L&E Battery pack comes with standard XT60 connectors* equipped.

Cables: Stefans Lipo Shop uses 12 AWG wires* on this packs. The high flexible silicon layer is rated up to 200°C. Cable length is about 7 centimetres.

Balancing plugs: Standard XT-system. Balancer wires* are very short (1.8 cm), which is a benefit in terms of getting them out of the prop-range on the aircraft. Still 1.8 cm are a little too short for comfortable handling when charging. Main power wires connect to the top, the balancer cable is connected at the bottom of the pack.

Break-in documentation

The battery followed the standard break-in-process: The pack is charged at a rate of 1C until CV-phase ends with current of 1/10C. The break-in phase consists of four charging cycles at 1C and four corresponding discharges at 1 C / 4C / 10C and 20 C.

Anomalies: No anomalies during break-in.

CV-Phase is short on this cell type. Balancing in normal mode took 0:59 min. Cell drift during charge was unobtrusive. This is for 1C charge (1.8 A).

Load Testing

The main part of this battery test will consists of different load test settings showing the battery performance. Constant load testing is used to judge the advertised C-ratings as well as look at cell drift under high loads. We also check on internal resistance once more. Next up is the dynamic current test, which simulates a „real“ flight with changing (=dynamic) loads. For test methodology please check the dedicated methodology page!

Constant Load Testing

Constant load testing follows a certain load pattern of different constant currents. Base load is 10 C. Current pulses at 50 C, 35 C, 20 C and 30 C are maintained for time intervals between 10 and 20 seconds. For more details please refer to the test methodology page.

Capacity Usage

During this test the pack delivered 1372 mAh. This is 74.3 % of nominal capacity. A very good result.

Average cell voltages

The following table lists the average voltages per cell, of the total pack, as well as the averaged value per cell as fraction of total voltage during phase of active load.

Cell 1Cell 2Cell 3Cell 4TotalAverage per cell
Avg. Voltages3.771 V3.772 V3.775 V3.770 V15.088 V3.772 V

Looking at average values the Dinogy pack performs very well. All cells stayed far above 3,7 V on average. An average value above 3,74 V / cell can be considered very good. The Dinogy Platinum Graphene 2.0 4S 1850 mAh V2.0 managed to score an average of 3.772 V / cell, which is nice!

Focus Voltages

Exceptionally interesting when testing a battery under a constant load for a longer period of time: the lowest voltage per cell just before load impulse is disabled. On top, you should have look at voltage recovery rate, that is: how fast do cell voltages rise again once load impulse is cut.

PhaseCell 1Cell 2Cell 3Cell 4Total
End of 50 C3.612 V3.630 V3.641 V3.663 V14.544 V
End of 35 C3.553 V3.564 V3.573 V3.583 V14.273 V
End of 20 C3.312 V 3.278 V 3.310 V 3.293 V 13.192 V
End of 30 C-----

Voltage sag is very low on the Dinogy Platinum V2.0 1850 mAh pack. It becomes visible that even the 50C phase brings no real trouble to the 1850-mAh-pack. No cell went below 3.60 V on the high load phase. Keep in mind, we are talking 92,5 A over a couple of seconds at 50C here.

Average voltage recovery per second

Those values are specific to the test setting and not valid for the pack in general! Still they allow an estimated guess about how fast voltages rise again after current spikes.

Cell 1Cell 2Cell 3Cell 4Total
Avg. Recovery0.167 V / s0.0156 V / s0.0146 / s0.0012 V / s0.059 V /s

As voltage sag in overall is very load (even on amp spikes), voltage recovers very quick accordingly. Nothing to complain here.

IR-Measurement

IR measurement is conducted using the four current pulses. Resistance for each cell is calculated in all four discharge phases. Shown values are averaged to cancel out different temperature points due to different discharge states during measurements.

Cell1234Total
Resistance [mΩ]2.192.012.152.188.53

Interpretation: The internal resistance of 2.13 mΩ average per cell indicates a „true“ C-rating of around  39 C (72.2 A). This is on the conservative side and represents a current draw that will make the pack last for a long time. This estimation falls in line with the nice voltage stability of the pack. This value is good result. Only the SLS NOC Race 1800 mAh 2N is still a few Cs stronger.

Dynamic Load Testing

The dynamic load testing setting consists of two separate discharge scenarios that have been developed of two different real-life FPV flights. Pattern one represents a high speed low proximity flight around the open field with some hovering to the end. Average load is around 22 A. Second pattern is a free-style flight around trees in the park with some current spikes near 70 A. Average load on this flight is around 13 A due to longer floating periods.

The last chart of this review sums up the usable capacity during all four load scenarios. Please note that this is only the capacity consumed by the electronic load! There are losses due to heating of the pack, which could be approximated (see testing methodology page). All four tests are cut when any cell goes below cut-off voltage of 3,3 V (or pack goes above 58 °C on any of the three probes). If you would push further and go down to 3,0 V/cell you will be able to squeeze out some mAh more, but at the cost of excessive heat generation and shortening of pack life-span. This value will most likely differ from what you get when flying on a quad as most people don’t monitor voltage on a per cell basis and therefore don’t even notice if voltage drops below 3,3 V/cell during punsh-outs (what’s not necessarily a good thing, though). For comparison, used capacity until 3,3 V/cell is reached is the base line in all battery reviews on Drone-Zone.de.

Conclusion

The new Dinogy Platinum Graphene 2.0 4S 1850 mAh 130 C V2.0 battery is a small sized pack with a capacity to weight ratio of 8.45 mAh/g. This value represents the typical higher weight for graphene batteries and falls in line with all the other graphene packs we have tested so far. Build quality of this battery is excellent.

The pack is rectangular shaped and keeps it shape under every load situation – no puffing what so ever! Voltage stability is very good. Cut-off should be chosen at 3,45 V / cell minimum.

Usable battery capacity is very good. The cell matching on our samples is almost perfect as well, absolutely nothing to complain about here.

In terms of performance we would rate this pack at astonishing 39 C continuous. This allows you to pull around 72.2 A without having to worry about the packs health too much. The performance of the new Platinum V2.0 series beats the old the Dinogy Ultra Graphene 2.0 series by a few Cs. It can’t catch up with the SLS NOC 1800 mAh 2N pack, though.

Unfortunately Dinogy also is trapped in the marketing race for high C-Ratings (to keep up with the often dishonest product brandings of the competition). Don’t let yourself fool by extreme C-ratings: Dinogy* still stands for highest performance batteries as this review shows once more – no matter the number on the battery label.

All in all, you get more than enough buffer for even the most demanding drone racers. As you can see in the dynamic load test, higher current spikes are handled very well. The battery almost seems to be a little bored even at highest loads.

The heating of the pack stays within the normal temperature range. High continuous draws will get the pack up to just a little higher temps to the end of the discharge cycle. Mounted on the racer the airflow will take care of more than sufficient cooling, though.

In the end 41.99 US-$ (MSRP) are well invested, if you are looking for a 1800 mAh FPV battery that will keep up with rising power demands.

For Dinogy fans who are looking to upgrade their battery collection the new Dinogy Platinum Graphene 2.0 V2.0 series is the way to go*. For folks new to the Dinogy universe: Buckle up, it’s going to be fun (once again)!
