Great customer service and product

Order was verified same day and shipped next day.

Shawn Helterbrand
36v 15a charger

Super fast delivery and so far great product.

Carson Warrix
36 volt charger

Small and lightweight, at 15 amps charges my battery very quickly. Would buy it again. Was a good decision!

Austin Pride
So far, so so good.

My 36V, 50AH powered my 36V Rhodan trolling motor for a legit 7+ hour run time in rough conditions and I still had 33% battery left at the end of day. Highly recommended. Super fast charging.

Peter Gobel
3615M charger

I like the charger just wished that it was a little more compact to allow for a way to mount it, instead of having to carry it outside the boat
