Anderson, the big 50A variant, example: https://www.amazon.com/dp/B07CHD4JCK
It does seem to take 5 hours to fully charge instead of 1 or 2. Im not particularly in a rush and I have solar panels but for $50 the price was right. There are $300 chargers out there but I couldnt find any (on Amazon) that went over 36V and I needed at least 40V. Maybe this will be an upgrade I do in the future to a higher amp charger.
The old charger for the lead acid had whats called an SB50 plug so I clipped the ends of my new charger and wired it into the SB50 connector below. I guess depends on what year/model carts but Ive seen a variety of different connectors. I could have directly wired/soldered everything up as well but I wanted the option to detach the charger if ever need be.
If you only want to install connectors, not pigtails, Anderson Power Pole Connectors are another option.
