Fitment: Fits 48 volt Yamaha G29/Drive 2007-2016 & Drive2 2017-up (Includes charger interlock) Features: Pre-Qualification Test Stage tests the condition of the battery and prepares battery with a proprietary and specialized Test Charge Algorithm to prepare battery pack for fast charge Cell-Balancing. The Equalization Stage balances battery cells and increases charged capacity to near 100% DPI computational algorithm computes the precise amount of Top-Off Charge which brings the battery to 100% state of charge Automatic A.C. Disconnection / Reconnection after charger has finished charging conserves energy while continuing the monitor and trickle charge battery Periodic Auto-Restart, when batteries are left in storage, assures battery pack is ready to go at the start of the season Universal I.E.C. input connector with A.C. line Power-Good and disruption green/red L.E.D. indicator with A.C. disconnect relay 32 Charge modes available via user accessible switch: Large and small capacity battery, flooded, AGM, sealed, multi-chemistry capable, downloadable algorithms for many other types of batteries, user enabled on-demand-cell-equalization charge
