 Safety

  • The upper part of the cell is over-insulated with a ring-shaped dielectric      material.

  • The entire cell block is surrounded by a multi-layers shield with mechanical      strength and dielectric insulated, outside-reinforced with an aluminized      film used in the spacecraft industry. All covering materials provide a      high sealing, improve thermal performance and contribute to the robustness      of the battery pack.

  • The battery pack is externally wrapped in a hard (Black & Blue) PVC      film.

36V 7.8Ah/8.7Ah /10.4Ah /10.5Ah/11.6Ah/14Ah(0.5C2A discharge) can be customized as your request.

 

Li-Ion (Lithium-Ion) is the most common cell for mobile applications – Ranging from mobile phones to usage of space applications.  These cells are very easy to come-by, the problem is assembling them correctly, with the proper electronics & control and verifying their performance.

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)

 

Basic features

  • Easy to assemble – short proto-type time.

  • Environmentally  Friendly – No cadmium, mercury or other heavy metals.

  • High Energy Density – ~210 Wh/Kg

  • Discharge currents: 2C max

  • Long Cycle Life – Charge and discharge can be repeated over 500 times (and >800 in most times) with stable discharge voltage during normal  operation.
