£ 269.66 - £ 649.95


The MLS series is designed to be extremely easy to install without any additional components. All the models comprise of a tough waterproof plastic case. This makes it a straight-forward replacement for most existing lead-acid batteries.The MLS series comes with an integrated safety switch, this saves installation and commissioning time. For higher capacity, multiple MLS batteries can easily be connected in parallel.

The MLS batteries are suited for many different applications where capacity up to 90 Ah is needed. Its compactness and low weight plus the fact that it is mountable in multiple orientations, make it ideal for portable applications such as mobile communications. The MLS is also often used for (UPS) backup power. Applications range from small boats and vehicles to security systems and industrial applications.
