HoneyCare 48V Sealed Lead Acid Battery Charger with Fuel Gauge - Smart MCU Controlled SLA/AGM/Gel/VRLA Battery Charger with Recovery Function for Scooters, Electric Bikes & Mobility Scooters - Perfect for Home, Workshop & Outdoor Use

As others have done, I retrofitted the alligator clamps to a standard 120V plug so I can plug into an AC outlet and then plug into my battery box to charge my ebike. It take a while to charge but it works very well, nice slow, trickle charge and charges from 40% to full overnight. I had my first one stolen, so I ordered it again, only this time I will install a security box to house it in and use star bit screws so that it can't get stolen again. I currently live on the 2nd floor and can't bring my bike inside for charging so the security box will have to do. I don't know what the thieves could possibly do with a specially retrofitted unit like I had, but they won't be able to steal it again without making a lot of noise, which will get them caught red handed! I use 4 of the 12 volt 18ah mighty max AGM batteries and it does just fine. Recommend it for anyone who uses AGM or sealed lead acid batteries. My 1000 watt front wheel always has an excellent pull after being charged overnight. I might note that the electric wheel I have will show no power when it reaches 48 volts or below, and the secret to keep going seems to be using less than full throttle. It will get up and go using full throttle but for longer distances, better to keep it dialed back and let it discharge slower.
