Why do we like Li-Ion cells

When we do not recommend to use Li-Ion cells

• Because Li-Ion from large companies are very reliable

• When our customer askes for very high currents.  The Li-Ion has relatively high Internal Resistance and therefor drops voltage in high currents

• Because Li-Ion cells are available.  Most of the brands are easy to purchase.

• When our customer has complex volume and wants max capacity.  Li-Ion is common in a few basic dimensions.  Most of the times can’t reach 100% volume usage.

• Because  Li-Ion has also very reliable and cost effective brands.

• When our customer wants minimum weight.  OUR LiPo is better than Li-Ion

• Because the majority of Li-Ion (from large companies) have all the certifications needed

• When our customer has a high temperature  problem (again, that IR)
