Robustness of Victron Lithium batteries?

Hi, I'm putting a solar system into a 4x4 overland vehicle and I was wondering how robust the Lithium Smart batteries are in regards to vehicle vibrations for off-road use and on badly corrugated roads. Would heavy duty AGMs be better suited?

Lithium cells are probably more robust than lead cells.

But cell interconnects are a problem with both types.

Physical cell encapsulation is also needed for both types to prevent swelling/movement.

Build your own battery? (I did).

@klim8skeptic did you make any notes when you built your own?

Its not hard to bolt 4 cells together ;).

Actually they vary and it depends on the battery construction, there are a number of ways of constructing a lithium battery. In general, pouch cell construction is the worst followed by prismatic, then cylindrical. Regarding cylindrical, the smaller the cells the more robust but cylindrical size is a trade off between manufacturing costs and size.

Hello, The lithium are quite equal to AGM, but be aware that extreme socks and vibration can cause failure on both chemistries.

Also consider viability of replacement in remote locations (if you're going to remote locations), and whether the remainder of your system can handle less than desirable replacement chemistries.
