Lithium Ion is by far the most commonly used battery today, is available both as prismatic and cylindrical.
The perfect match between performance, reliability, price, cyclelife and energydensity. Cells starts at approx 1000mAh and goes up to 8000mAh – which gives you endless possibilities.
Li-ion batteries are well suited for big batterypacks with many cells.
Lithium Polymer has very high energy density and is available in very small sizes.
Availbale in every prismatic size you desire. Produced in China and are a very cheap alternative to the other lithium technologies. Cells starts at approx. 50mAh and goes up to approx. 5000mAh.
Li-Po batteries are well suited for 1S1P packs.
Lithium Iron Phosphate has extremely long cyclelife and comes as prismatic pouch cells.
Pricewise roughly right in between Li-Ion and Li-Po. Wide temperature range for discharge allow these cells to be used for multiple purposes. Has low energydensity so cells are bigger and heavier than the other lithium technologies. Cells starts at approx. 6000mAh and up to 30000mAh.
LiFePO4 batteries are very well suited for big batterypacks with many cells.
