Dear K. Kitudom krub,
Thank you for your cable information krub.
Please see dimension as per PDF krub.
It seems that the space is enough to install new battery krub.
And we can use battery as 2x100% krub.
By the way, please kindly advice that can you provide the new 2 stage racks for the existing battery (SBL470-2 at 1 stage) and new battery ( UP1L280 at 2 stage ?
If you have any query, please let me know
