https://www.revolutiongolfcars.com/p...-ds-series-48v You are looking at $282 for an OBC (Tahoe may discount it for a member - have to ask him)
https://shop.cartsunlimited.net/DPI-...harger-DPI.htm scottyb is $295 for a DPI Accusense which is a smart charger.
OBC's are good and have a lot of points to them, but they are still old technology compared to today's smart chargers of which in my opinion, the DPI leads the pack.
Make the choice you feel is best for your needs.
