The main functions: 1. Advanced Technology: Use the machine switching power skill, and the intelligent charging technology, which has high reliability. 2. High stability: The switch was made up of military use IC. Stable, reliable, and less failure. 3. Using the pulse width modulation technology, high power factor, less ripple factor, and has less Interference to other machines. 4. Charging characteristics: Three-stage charging modes: constant current charge at the beginning, avoid wreck a batteries. When the battery comes to the max voltage, it will turn to the constant voltage, so as to improve the capability of batteries, and increase the conversion rate as well. Trickle can balance every battery got charged. Usage: Electric Forklift Batteries, Auto Motive Batteries, Electric sightseeing Batteries, Electric cars batteries, motorcycle batteries, and DC Power Supply
