Big Cat 48V Fast Charger- Smart charge 2 hours!

I purchased this charger and was expecting what was pictured. I didn’t receive the exact one pictures but the charger I received had identical specs. I wanted a fast charger for when I go on long rides and want to top off the battery. I had upgraded by battery from 13ah to 18ah. The original charger took around 8 hours plus to charge the 18ah battery. The new charger takes between 3.5-4 hours when completely drained. The new charger is larger and has a built in fan. I still use the original when charging over night and there is no rush to charge the battery. The new larger charger charges at 5a as opposed to the old 2a that came with the bike. The new charger is plastic. Feels like it’s constructed well. If you ride allot and use your bike for commuting, this is a must have. I keep this in my bike bag and take it every where I go. I’m happy with this purchase.
