The Integrel control system supports both lithium ion batteries and lead acid batteries (however we do not recommend use of lead-acid). 

We will recommend battery type when helping you specify your system. The key factor in selecting batteries is that they must be capable of high charge rates in order to minimise the amount of time taken to recharge and to make the most of the high power output available. 

The Integrel generator is software limited to 170A and 9kW allowing us to charge a typical 48V bank at the 1C rate, which is the amp hour rating normally quoted by the battery manufacturer.
