FAQs

Can I replace AGM with Slimline LiFePO4 directly?
Yes these are 12.8V batteries designed as drop‑in replacements for most 12V systems. Ensure your charger/regulator supports LiFePO4 profiles.
Do I need a separate BMS?
No. An integrated Smart BMS protects against over/under‑voltage, over‑current, and temperature extremes.
What’s the expected lifespan?
Under typical use, LiFePO4 delivers significantly longer service life, often up to 5× that of AGM batteries.
