WMH Racing Battery Wizard
New from WMH Racing is the Battery Wizard, a discharge measuring device for your 1s and 2s batteries. This tool is ideal for comparing, knowing when to retire, and knowing what kind of performance your battery really has. No more seeing the Wizard behind the curtain, for “good” packs. Having the ability to test your batteries, affords you knowledge on how much: power you will be able to have, for how long, and how much you will fade. In short the Battery Wizard will do for batteries as the motorlyser did for motor tuning. Key Features include Internal resistance measurement and the display of battery discharge curve, milestones, and raw data every 15 seconds. With a choice of discharge rate: 1-45 amps* for 1s and 2s batteries, it reaches desired amps in approximately 2 seconds and has a customizable cut off voltage.
