The Australian Financial Press (AFP) has just released its battery ranking, and its findings show that a combination of lithium-ion and lithium-air batteries (in the form of lithium ion) is the best way to go.
Weighing in at 4.3kg and 3.4kg respectively, the batteries are still a little light on the tallies.
We think it’s because lithium ion batteries are more expensive, so you’re looking at a premium over the range batteries that are available.
If you want the best battery, though, we recommend the high-voltage Li-ion battery, which is a lot cheaper, and delivers up to 400Wh.
There are two different batteries in the battery rankings, and both of them can deliver around 400Wh of energy per kilogram, making them the two cheapest choices.
The second battery, the lithium-cadmium-polymer battery, has the best energy density of the three, but has a higher price tag.
In fact, we’d say the Li-cab batteries are the cheapest in terms of price.
The batteries that we tested are from the US and Europe, with some US-made batteries also being found.
The battery prices have been calculated using an average price of US$15 per kilowatt-hour (kWh) and US$18 per kilawatt-hours (kW).
The cost of the batteries we tested range from $1.70 to $2.50 per kWh, depending on the size of the battery, weight, and capacity.
