LiFePO4 Battery Advantages



12V LiFePO4 batteries support series and parallel. Up to 4 batteries in series or up to 4 in parallel for 12V, 24V, 36V and 48V systems. 48V lithium batteries support parallel up to 15-16 units.


Canbat lithium batteries are designed as a drop-in replacement for lead-acid batteries. The dimensions of our lithium batteries are the same as the dimensions of lead-acid batteries, much lighter in weight.


Canbat lithium batteries are super lightweight due to our high energy density lithium cells. They are 60% lighter than sealed lead-acid batteries. Installing and moving the batteries is very simple.


LiFePO4 batteries can be discharged to 100% and can also be discharged at a high rate of up to 1C for most models while maintaining a high energy capacity. Refer to the datasheets for specific specs.


LiFePO4 batteries can reach more than 3000 cycles, and its cycle life can reach more than 6 years.
