If you are reading this then chances are you are the kind of person who demands the best from their marine or RV batteries, and when only the best will do then you are looking for a DCS 12V Lithium Ion Battery. With a 100Ah or 75Ah option plus other sizes and capacities released soon, it is easy to get the right battery for your marine, recreational, mobility, communications or other battery applications.

These are also a direct replacement upgrade of your current AGM, gel or lead-acid battery, making upgrading from your current battery easy.

DCS 12V Lithium Ion Batteries have tremendous advantages in weight, performance, reliability and service life when compared to that of traditional lead acid batteries.

A DCS 12V 100Ah Lithium Ion battery weighs in at a mere 14kg. Compared to a comparative lead acid battery (with the same usable energy) that weighs in at over 6okg! That’s more than 4 times the weight of a DCS 12V Lithium Ion Battery!

There are also the dimensions. Your DCS 12V 100Ah Lithium Ion Battery dimensions are as follows: 328mm long x 171mm wide x 215mm tall. Compared again to a similar lead acid battery with dimensions as follows: 522mm long x 238mm wide x 218mm tall. This makes your DCS 12V 100Ah Lithium Ion Battery almost 50% smaller – leaving more room for other equipment and ventilation.

Here are some other key features if you aren’t already convinced:

·      Fully sealed and waterproof design

·      Automatic protection from over charge, over discharge and over current

·      Marine grade stainless steel 316 terminals

·      Built in Battery Management System (BMS)

·      Automatic cell balancing

·      Internal chemistry specifically designed for deep cycle applications

·      Self discharge at less than 3% per month – so will still be able to turn over an engine after sitting unused for 12 months

·      2000 cycles at 80% depth of discharge under normal conditions

Engineered to cope with the unique and harsh Australian environment its comforting to know that DCS 12V Lithium Ion Batteries can last up to 5000 cycles and come with a 3 year warranty – we stand by the performance and quality of our product.

So a DCS 12V Lithium Ion battery surpasses all other batteries in weight, size, performance and reliability.  So for a product you can rely on and trust to get the job done every time, it has to be a DCS 12V Lithium Ion Battery. Why waste your time and money on anything else?
