Product Code: 1507-41383-331348 Category:


The KS-SB210 is a 12V 210Ah high capacity deep cycle lithium leisure battery that has been specifically manufactured to easily fit under the front drivers, or passengers seat of a Sevel s.p.a X250 or X290 commercial vehicle. The van chassis favoured by the majority of coachbuilders and generically used since 2007 by Fiat’s Ducato, Peugeot’s Boxer and Citroen’s Jumper & Relay vans. The battery case is constructed from rugged powder coated steel and features floor fixing brackets (removable) for mounting security. Internally the battery features our renown high current, low temperature charge protected BMS with Bluetooth communication to our KS Energy Android/Apple app. The battery with its integral carry handle weighs in just under 24Kg and any number may be paralleled.

Built using Galvanised Steel
