Battery Types

What types of battery are there?

There are many types of batteries - some heavier and cheaper, others lighter and with more capacity, but higher cost.  Read more...

The most commonly used in electric bikes is Lithium Manganese Oxide (LiMnO2).  Krys uses this type of battery on some of its lower cost vehicles.  It has a lower cost and is suitable for most bikes...however it has recently been made obsolete by Lithium Nano Phosphate and Lithium Iron Phosphate - read more below.

A better formulation than the common LiMnO2 is Lithium Iron Phosphate (LiFePO4, or LFP) and Lithium Nano Phosphate as used by Krys in its high performance vehicles.  A battery with LiFePO4 can have twice the life of LiMnO2 and up to 5 to 10 times that of lead acid batteries (up to 2000 charges).  Many Krys vehicles come with a LiFePO4 battery, even though they are about 20% higher cost than LiMnO2.

Nano batteries are capable of much faster recharge times, in the order of seconds or minutes instead of hours.

A new and still emerging technology is capacitance batteries.  These are a giant capacitor about the same size and weight as a lithium battery and also holding about the same energy density but can be very rapid charging.  The disadvantages of these are the requirement for a specialised charging station and much higher cost.  Krys will likely adopt capacitance batteries when the technology has been developed and refined further to remove all the safety issues with such a high power capacity.
