2s-life-700-mah-zippy-5c-battery

The 2S 6.6V 700 mAh Zippy Flightmax LiFe batteries are intended for use as a receiver battery packs in remote control models using nitro engines, but they can also be used as a main battery in other remote control cars and other RC models. The Zippy brand is used by one of the largest Chinese online stores for radio controlled models and is considered to offer good quality at a good price, but as with other cheaper Chinese lithium-based rechargeable batteries we are expecting to get results a bit lower than advertised, but let us see if we might be pleasantly surprised this time…

We have started the tests with a 1C discharge rate (0.7A) for the 2S 6.6V 700 mAh Zippy Flightmax LiFe battery and we’ve managed to get 653 mAh as a maximum capacity, a value that is a bit shorter than the official rating of the battery of 700 mAh. So the battery should’ve been labeled 650 mAh instead of 700 mAh as apparently it cannot provide 700 mAh at 1C discharge rate, but the interesting thing is that this battery can provide the same capacity with a discharge rate of up to 3C and going to the maximum rating of 5C as a constant discharge rate we are seeing a bit of a decrease in the useable capacity where we got 599 mAh. So the discharge rating is Ok, the capacity however is labeled with 50 mAh more than it should’ve been, in the end these batteries are handling pretty well, so if a 650 mAh LiFePo4 battery is what you need at a good price, then you might consider getting these Zippy Flightmax batteries.

The performance of the 2S 6.6V 700 mAh Zippy Flightmax LiFe Battery in our tests:

– 653 mAh at 0.7A load (1.0C)
– 653 mAh at 1.4A load (2.0C)
– 653 mAh at 2.1A load (3.0C)
– 599 mAh at 3.5A load (5.0C)

What you should have in mind here as well as with other small batteries that use thin cables passing higher current such as 10A (the burst load rating of this battery) or even higher as a constant load is not a good idea as they will get hot and may melt and short the battery, and that is definitely something you don’t want!

1-5v-aa-xcell-alkaline-battery

The 1.5V AA Xcell Alkaline batteries don’t seem as something special, but we’ve decided to give them a try and see how good will they be able to perform in our tests. The batteries we’ve used for testing were with an expiration date of just the year 2017, no specific month, so they should be with either 4 or 5 years of shelf life.


1-5v-aa-xcell-alkaline-battery-capacity

Starting our test of the 1.5V AA Xcell Alkaline batteries as we usually do with a low constant current discharge rate of 0.1A we have managed to get 2063 mAh as capacity. With that capacity they do not manage to get into our top 10 of best AA-size Alkaline batteries, though the level of capacity they offer is still more than decent if the price is right. Increasing the level of constant current load that we are testing with to 0.2A we still get a decent useable capacity, but past that the performance gets even worse, so better not use these batteries for higher power drain applications.

The performance of the 1.5V AA Xcell Alkaline batteries in our tests:

– 2063 mAh at 0.1A load
– 1586 mAh at 0.2A load
– 761 mAh at 0.5A load
– 267 mAh at 1.0A load

– 2.521 Wh at 0.1A load
– 1.858 Wh at 0.2A load
– 0.859 Wh at 0.5A load
– 0.293 Wh at 1.0A load

1-5v-aaa-panasonic-pro-power-alkaline-battery

The 1.5V AAA Panasonic Pro Power Alkaline are supposed to offer premium energy for personal appliances and should be ideal for high and medium drain appliances according to Panasonic. They are almost the highest-end Alkaline batteries that the company offers, the only supposedly better option are the ones in the Evolta range. The Panasonic Pro Power Alkaline batteries we tested here were with an expiration date of 01-2018 meaning that they should be offering at least 5 years shelf life.


1-5v-aaa-panasonic-pro-power-alkaline-battery-capacity

Starting our test as we usually do with a low constant current discharge rate of 0.1A we have managed to get 794 mAh as capacity from the 1.5V AAA Panasonic Pro Power Alkaline batteries, or a it disappointing result placing them more in the mid-range among the AAA size Alkaline batteries we have tested so far. At 0.2A and 0.3A constant current discharge rates the batteries still perform quite well, though at a level of 0.5A there is a more significant drop in the usable capacity you can get, meaning that these batteries are not going to be handling well in devices that have quite high power requirements and are using AAA-size batteries.

The performance of the 1.5V AAA Panasonic Pro Power Alkaline batteries in our tests:

– 794 mAh at 0.1A load
– 593 mAh at 0.2A load
– 492 mAh at 0.3A load
– 159 mAh at 0.5A load

– 0.964 Wh at 0.1A load
– 0.707 Wh at 0.2A load
– 0.568 Wh at 0.3A load
– 0.173 Wh at 0.5A load
