Installation & Maintenance
LiFePO4 batteries are designed to be maintenance-free throughout their service life. However, following proper installation and usage guidelines will maximize performance and longevity:
- Install in a well-ventilated area away from extreme heat sources
- Use appropriate charging equipment with LiFePO4 charging profiles
- Avoid deep discharges below 20% state of charge when possible
- For long-term storage, maintain at 40-60% state of charge
- Periodically inspect connections for corrosion or looseness
- Follow all safety guidelines in the user manual
Warranty Information:
All ampereX LiFePO4 batteries come with a 5-year limited warranty. Extended warranty options are available.
