## Questions & Answers

**Q: Whats the difference with the PRO version ?**
A: Thank you for your inquiry. Our LiFePO4 PRO version is built with only the highest quality premium materials and has a 10-year warranty.

**Q: Is it marine rated?  can it last in salt air?**
A: Not marine rated.  It is sealed, I use mine in a marine application with no issues.

**Q: Is the any advantage to running 2 100amp batteries over just running this 200 amp ?**
A: There is no advantage from an operational standpoint. Generally one, 200 amp hour battery costs less than two, 100 amp hour batteries. Just be sure the 200 amp hour battery will fit in the space where it will be installed as they can be larger than a standard battery.

**Q: What are the charging specifications?  does it work with typical car/marine engines with 12 volt systems?  lipo usually needs specific charge requirem**
A: Thank you for your inquiry. Yes, LiFePO4 batteries have a 14.4V charging voltage and this battery has a Max. Continue Charge Current of 50A. It should be compatible with 12V electric motors but not as a starter battery as it was not designed to do that.
