Using LiFePO4 batteries as starting batteries for the fuel cars

Q: Can the 12V LFP/LFYP batteries be used as starting batteries for the regular vehicles?

A:  Yes. We highly recommend using the LFP/LFYP batteries for starting vehicles. Their performance is much better than the lead-acid batteries.

Q: What are the advantages of the LFP/LFYP batteries?

A:  LiFePO4 batteries are able to provide much higher starting current than the lead-acid batteries (SLA). They work even in extreme low temperatures (bellow –35 deg. C).  They cannot “get frozen” like SLA batteries. They contain no acids and require no special care. Their life span is 10 years and more, while SLA batteries may last just 4 to 5 years.   There are no known disadvantages when using LFP/LFYP batteries.

Q: Which battery model is sufficient to start a normal gasoline car?  

A:  LP 12V 40Ah is sufficient for any range of starting batteries up to 65 Ah of the original lead acid value. For vehicles with larger battery we recommend LP12V 100Ah.  For trucks and machinery (using 24V system) we recommend 2 pcs of LP12V 100Ah connected in serial. For campers, mobile homes and other vehicles with large battery we suggest to use 12V 200Ah, by connecting two 100Ah batteries in parallel.

Q: What are the limitations when using the 12V LFP/LFYP batteries in cold winter season?

A: There are no limitations.  The 12V LiFePO4 batteries perform very well under low temperatures. We highly recommend to replace the SLA battery with LFP especially if your vehicle is parked out-side and gets very cold.  The 12V LFP/LFYP batteries are ideal for countries like Canada, Scandinavian lands, Russia – Siberia,  and other cold regions.
