Pouch Cell Battery Pack Design

Eliminating the metal enclosure reduces weight but the cell needs support and allowance to expand in the battery compartment.

Pouch cell battery pack design.

The best thing about these lifepo4 lithium batteries is that they can be connected in series and parallel to make a 12 cell pack of 1 2 8v 90ah 4s3p 9 6v 120ah 3s4p or 19 2v 60ah 6s2p to configure your battery pack exactly as you want. The pouch cell makes most efficient use of space and achieves 90 95 percent packaging efficiency the highest among battery packs. See also cell construction. Battery pack design considerations and construction details.

However lifepo4 is considered the most fire safe sometimes found as a starter battery on small aircraft and they also typically last about twice as long as the common nca ncm 18650 cell packs. The 30ah pouch cell is a kind of lifepo4 cell with good power and energy. Packing cells in a tube 3 cells.
