📊 Technical Specifications

🏕️ Engineered for Multi-Scenario Applications

🚐 1. Premium RV & Camper Van Upgrades

Traditional 12V systems require thick, dangerous wiring for modern appliances. Upgrading to the 24V solar battery kit reduces current draw, minimizes heat, and provides days of boondocking power for your off-grid overland adventures.

⛵ 2. Marine & Sailboat House Batteries

With standard IP-rated protection potential and ultra-stable LiFePO4 chemistry, this 24V314Ah marine battery kit provides relentless power for trolling motors, navigation, and onboard living systems.

🏡 3. Off-Grid Cabins & Solar Energy Storage

An ideal building block for building a reliable, compact home backup power system. Easily pairs with 2kW-3kW inverters to back up your critical household loads during unexpected power outages.

 

Enclosure Assembly Reference: This image shows the completed setup with cells inside (for demonstration only). Please note that this is an empty DIY kit; battery cells must be ordered separately.

 



Why Build With AmpBird

Everything for a safe, reliable DIY pack.

Pre-Programmed BMS

The included BMS ships configured for your cell count and chemistry. No laptop, no parameter guesswork.

Save vs Pre-Built
