Everything you need to know about BUKNUWO smart lithium batteries.
LiFePO4 (Lithium Iron Phosphate) is the safest and longest-lasting lithium chemistry. It offers 5,000+ cycles, no thermal runaway, and stable performance across a wide temperature range — vastly better than lead-acid or NMC.
Yes. Our 12V/24V/36V/48V batteries are designed to drop into existing lead-acid systems. You may need a lithium-compatible charger for optimal performance.
All smart series batteries include Bluetooth 5.0. Pair with our free iOS/Android app to monitor SOC, voltage, current, temperature, and per-cell health.
Every battery comes with a 5-year warranty and is rated for 5,000+ cycles at 80% depth of discharge — typically 10+ years of daily use.
We ship to the USA, Canada, EU, UK, Australia, and most of Southeast Asia. Free shipping on orders over $99 within the continental US.
