48V 15A Lifepo4 Battery Charger - Waterproof Lithium Golf Cart Charger with Intelligent Protection & Trickle Charge | Fast Charging for 48V Golf Carts, Electric Scooters & Mobility Scooters | Perfect for Outdoor & Marine Use

15 amps is a really decent charge rate, and the fact this charger has a trickle charge / maintenance mode to keep the battery topped off makes this a "set it and forget it" charger, which I'm a big fan of. It's IP67 rated, so you should be ok with this even in a little rain. You might not want to use it to charge under water, however, despite their cute photo.Overall, this is a rock solid charger for 48v LiFePO4 batteries. It works great, and I have no complaints!
