What will happen if I add two strings (1 string = 16 x 12V 100AH) of 12V 100AH VRLA Maintenance Free batteries as external battery bank to SUVTP30KH4B4S?

Appreciate your earliest feedback.

You must remove the internal batteries if you are going to use larger external batteries.

You will extend your run-time.
However, these batteries will be "unmanaged". There will be no reports that the batteries exist, or don't exist. There will be no reports of battery failures.
Once a run-time calibration has been run the projected run-time will be close to accurate, but, should this string be removed (or fail) the projected run-time will be very inaccurate.

Thanks.. will it afftect the internal 12V 7AH batteries.

There are 3 rows of internal battery packs installed. Will the external 12V 100AH batteries affect the internal batteries?
