The revolutionary 'green' LP Charger Series supports the Digital Battery Series and features an efficient charging algorithm for multi-chemistry, simultaneous charging. The algorithm ensures rapid charging of up to four batteries at a time, all while conserving energy, eliminating waste, and reducing total cost of ownership. The Performance Charger series is nearly 40% more efficient than traditional chargers, rendering large power supplies virtually obsolete. New green charger: Charges faster using less power. Low profile design enables stackability for strategic storage. . Charging algorithm is 40% more efficient than traditional chargers. Multi-chemistry charging of the fast chargers reduces costs whilst maintaining performance. Automatically detects which battery has the strongest charge and prioritizes it, ensuring that a fully charged battery is always available in the shortest amount of time possible.
