Both of those packs are built from soft poly cells = less weight then hard cased cylinder or prismatic cells but more easily damaged (protect your pack, don't let it take a physical hit with poly packs !!!).

The first product you linked too is duct-tape/shrink-wrapped pack and thus very-difficult/impossible to repair. When the pack goes the whole thing goes, all or nothing.

The second product you linked too uses the soft cells inside a hard sealed case that can apparently be opened with a screw-driver. That pack may be repairable since it may be possible to access individual cells. Obtaining replacement cells to match could be an issue and it is an unknown as to whether they are glued, taped, etc . . . together inside the case or not. Could be a repairable pack but maybe not. The hard shell case probably offers better protection then just duct-tape/shrink-wrap in a bag like the first pack you linked too.


Price is excellent and lower then a Ping battery which is the usually "go to" for a soft poly LiFePO4 poly pack for an e-bike. Price is even lower then building a pack up from the prismatic cell solar power packs like I do (unlike Ping with is more expensive then that) but won't be a repairable pack like I get with using prismatic cells.
