EarthX Lithium Batteries is Excited to Announce FAA STC Approval for Cessna 172N, 172P. 172Q, 172R, 172S Aircraft!
Why make the switch?
- The weight savings is phenomenal; if you’re replacing the RG24-11, you go from a 26.5-pound battery to a 7.2-pound battery, that is 19.3 pounds of instant weight reduction. This weight savings can increase your useful load, save fuel costs, increase climb rate, and have shorter take off roll.
- The capacity of the lead acid battery was 11Ah, the EarthX is 11.7Ah, a slight increase.
- The cold cranking of the lead acid battery was 160, the EarthX is 400, more than double the cranking.
- The life span of an EarthX battery is rated to be twice that of a lead acid battery.
- The EarthX cannot freeze, boil over, lose electrolyte, corrode, or sulfate. Zero caustic acid.
- On average, this battery is only $100 more than the lead acid battery it is replacing.
- One of the most exciting features is the EarthX battery as a battery management system (BMS). A lead acid battery cannot provide this level or information to the pilot as there is no way to implement a battery management system inside the unit (acid does not play well with others). This battery can communicate directly to the pilot if there is anything outside of normal with a flashing or solid LED light to alert you to investigate. This provides useful information not only for the pilot, but also your mechanic, to make the best-informed decisions.
FAQs
Q: Do I need to change anything to my alternator/regulator in my plane?
A: NO, our battery has the same charging profile as a lead acid battery.
Q: Is it a problem if my Amp Hour is less than it used to be with a lead acid battery?
A: NO. Lead acid batteries need more amps to achieve cranking power vs. our battery needs less amp hours to achieve the necessary cranking power while still adhering to safety requirements.
Q: Do I need to perform a new weight and balance?
A: YES, the FAA requires that any STC requires weight and balance.
Q: Do you charge for STC paperwork?
A: NO.
Q: What is my initial investment for this switch?
A: $1,194 includes the battery and installation kit.
