KS-Energy 12V 200AH Seat Base lithium battery with Bluetooth high power BMS

The KS-SB200B is a high performance 200AH deep cycle lithium battery that has been designed specifically to under the seat base area of the Sevel X250/X290 based chassis. ie. the front seats of the Fiat Ducato, Peugeot Boxer or Citroen Relay chassis base that is favoured by many British and European motorhome / campervan manufacturers.


Main Features

Compact seat base footprint with integral floor fixing brackets (removable), automatic low temperature charge protection, Bluetooth monitoring via the KS Energy free app. Over charge voltage, over current cut out and under voltage cut out makes this battery virtually abuse proof. It may be configured for unlimited parallel configuration and its 330*270*180mm compact size can also make it ideal for other space limited locations.
