Buying Guide
When choosing a solar battery, consider chemistry, capacity, weight, cycle life, and protection features. LiFePO4 offers long cycle life, better safety, and lighter weight, making it a strong choice for most solar setups. AGM is often more budget-friendly but heavier and with lower cycle life. For larger systems, prioritize higher Ah ratings and a robust BMS. If you plan frequent cycling or outdoor use, IP67 waterproofing and temperature management are valuable.
