The 1S 3.7V 300 mAh Gens Ace 30C LiPo batteries are designed for use with small scale RC helicopters such as Blade mCPX and other similar models such as WLtoys v922, Turnigy FBL100 and others. These are intended to be used as an alternative to the stock battery and provide higher capacity and higher discharge rates to ensure longer flight time and better performance. We are used seeing very good results from Gens Ace batteries so far and we are having high expectations for these batteries, but let us see how they will perform in our tests.

Official Battery Specifications:

– Capacity: 300mAh
– Voltage: 3.7V
– Max Continuous Discharge: 30C (9A)
– Max Burst Discharge: 60C (18A)
– Weight: 7.8 g
– Dimensions: 42.3×18.83×6.98 mm
– Charge Rate: 1-3C Recommended, 5C Max
– Discharge Plug: E-Flight Ultra Micro

We have started the tests with a 1C discharge rate (0.3A) for the 1S 3.7V 300 mAh Gens Ace 30C LiPo battery and we’ve managed to get 308 mAh as a maximum capacity. This is a bit more than the manufacturer rating for this battery or with other words good start for the battery as we were expecting the Gens Ace meets its capacity rating. However what comes as a not so good surprise is that the constant discharge rate is about 20C maximum and not 30C as the specifications say it should be. Andjust to be sure it is not a problem with a particular unit, we have tested multiple batteries and all of them were not able to show better results. Gens Ace also sell 1S 300 mAh batteries with 15C rating and there could be some mix-up, however the boxes of the four batteries we have tested say that we’ve received the 30C model and not the 15C (we have ordered the one with 30C discharge rate). So a bit of a disappointment from this particular product from Gens Ace, but this just shows that not all of their products may be so good as we expect them to be.

The performance of the 1S 3.7V 300 mAh Gens Ace 30C LiPo battery in our tests:

– 308 mAh at 0.3A load (1C)
– 284 mAh at 1.5A load (5C)
– 280 mAh at 3.0A load (10C)
– 267 mAh at 4.5A load (15C)
– 214 mAh at 6.0A load (20C)
– 20 mAh at 7.5A load (25C)

1S 3.7V 120 mAh Gens Ace 15C LiPo Battery Tests

The 1S 3.7V 120 mAh Gens Ace 15C LiPo batteries with Nine Eagle type plug are used in various small remote controlled helicopters, especially in many of the Chinese brands and not only in Nine Eagle’s models. Gens Ace’s LiPo batteries have so far shown very good results in our tests, so we have high expectations for this battery as well as it could turn out to be a good upgrade option over the original LiPo batteries that may have inflated discharge ratings sold by the companies that make RC helicopters. As you can see this Gens Ace battery does not have a very high discharge rating at only 15C constant and 30C burst, but unlike many other Chinese LiPo batteries we’ve seen Gens Ace’s batteries to actually meet these specs in actual conditions.

Official Battery Specifications:

– Capacity: 120mAh
– Voltage: 3.7V
– Max Continuous Discharge: 15C (1.8A)
– Max Burst Discharge: 30C (3.6A)
– Weight: 3.9 g
– Dimensions: 48.16×12.16×5.08 mm
– Discharge Plug: NINE EAGLE Type
– Charge Rate: 1-3C Recommended, 5C Max

We have started the tests with a 1C discharge rate (0.12A) for the 1S 3.7V 120 mAh Gens Ace 15C LiPo battery and we’ve managed to get 130 mAh as a maximum capacity, a value that is a bit over the rated capacity of 120 mAh and that is definitely a good thing. Increasing the constant current discharge load at 5C, 10C and even 15C and the battery still manages to perform great, meeting the manufacturers specifications. In fact we suspect that even at 20C constant current discharge rate this battery will still manage to handle pretty well judging by the results we are getting from it. So great job with this battery as well for Gens Ace, a company that is continuing to build up a very good reputation for its battery products made for remote controlled models – planes, helicopters, cars, boats etc.

The performance of the 1S 3.7V 120 mAh Gens Ace 15C LiPo Battery in our tests:

– 130 mAh at 0.12A load (1.0C)
– 116 mAh at 0.6A load (5.0C)
– 115 mAh at 1.2A load (10.0C)
– 111 mAh at 1.8A load (15.0C)

2S 7.4V 350 mAh Gens Ace 20C LiPo Battery Tests

The 2S 7.4V 350 mAh Gens Ace 30C LiPo batteries are intended for use mostly in aircraft RC models such as helicopters and planes. These compact LiPo batteries have a pretty high discharge and charge ratings that we need to confirm in our tests. What is important to note is that the maximum discharge rates mentioned in the specifications are for quite high Amps and the small cables and connectors of the battery may not be able to handle them well.

Official Battery Specifications:

– Capacity: 350mAh
– Voltage: 7.4V
– Max Continuous Discharge: 30C (10.5A)
– Max Burst Discharge: 60C (21A)
– Weight: 25g
– Dimensions: 54,2×30,2×7,8 mm
– Balance Plug: JST-PHR
– Discharge Plug: n/a
– Charge Rate: 1-3C Recommended, 5C Max


2s-7-4v-350-mah-gens-ace-30c-lipo-battery-capacity

Starting the tests with a 1C discharge rate (0.35A) for the 2S 7.4V 350 mAh Gens Ace 30C LiPo battery we’ve managed to get 381 mAh as a maximum capacity, a value that is about 9% higher than the official rating of the battery, so definitely a good thing here. Furthermore up to 25C constant current discharge rate the battery still manages to provide 363 mAh, still more than the rated capacity, though at that rate we’ve measured the battery ending up discharged with a temperature of 68 degrees Celsius or a bit high than the 60 degrees safe zone. The more serious problem however became apparent with the 30C constant current discharge rate test where 10.5 Amps need to pass through the small cables of the battery and this makes them very hot – up to 100 degrees and that is dangerous as they or the connector can melt and short the battery!

The performance of the 2S 7.4V 350 mAh Gens Ace 30C LiPo Battery in our tests:

– 381 mAh at 0.35A load (1C)
– 378 mAh at 1.75A load (5C)
– 376 mAh at 3.50A load (10C)
– 375 mAh at 5.25A load (15C)
– 370 mAh at 7.00A load (20C)
– 363 mAh at 8.75A load (25C)
– 287 mAh at 10.5A load (30C)

While the 2S 7.4V 350 mAh Gens Ace 30C LiPo batteries are capable of handling a constant discharge rate of up to 30C as their specifications say the battery cables used are not designed to properly handle the 30C constant discharge rate!
