powertech lithium iron phosphate lifepo4 batteries are the most significant development in large commercial battery storage technology since nickel nickel cadmium technology is largely obsolete they are very different internally from conventional lead management system and this is one of the main reasons why lithium batteries have far longer life • much lighter than lead acid and agm batteries • robust lifepo4 cells • excellent life span powertech 12.8v lithium deep cycle batteries the next generation of power storage is here! these lifepo4 batteries weigh less than half of their absolutely perfect for high capacity portable power lithium lithium deep cycle battery capacity 7ah powertech lithium lithium deep-cycle battery continuous current lithium all prices are in australian dollars under a severe short circuit a lead acid battery can very rapidly heat up to the point where the sulphuric acid boils short circuits peak current remember all of this when making simple price comparisons with the two battery types internal battery management system powertech lithium lithium deep-cycle battery helpful hint weight 1kg 1.5kg 2.5kg 3.5kg year warranty notes on charging while the internal battery management system will take care of recommend using a charger which is chargers are developed to work in the optimum method for recharging providing longer service life if you're installing them as a house between your main battery system and the house batteries is also dual input multi-stage if you're charging from mains power we recommend the following chargers • mb3621 multi-stage charger if you are installing them off grid we recommend upgrading your charge controller to an mppt charge controller cat qty 1+ qty 10+ qty 20+
