Q: How many lithium batteries do I need for my solar system?

Calculate based on daily energy consumption and desired backup hours . If consuming 5 kWh daily and wanting 12-hour backup , you need 2.5 kWh storage minimum. Budget ₨175,000 per kWh for purchasing decisions.

Q: <strong>Can I mix different lithium battery brands together?</strong>

Strictly not recommended. Different brands have varying voltage outputs, discharge rates, and BMS characteristics creating imbalances. Stack identical batteries from same manufacturer only.

Q: What's the actual lifespan of lithium batteries in Pakistan climate?

Quality lithium batteries last 8-12 years in Pakistan's hot climate compared to 10-15 years in cool climates. Extreme heat (40°C+) accelerates degradation requiring proper ventilation and mounting in shaded, cool locations.

Q: <strong>Are lithium batteries safe for residential use?</strong>

Yes, LiFePO₄ lithium batteries are inherently safer than lithium-polymer or lithium-cobalt variants. They won't explode or catch fire even when damaged. Budget batteries from unverified manufacturers may lack proper thermal protection —stick to established brands.
