I notice how hot my charger gets when in use. It is a 2a unit. Wondering if anyone here has a unit with a cooling fan? Where did you buy it?
Thanks!

I have two from Luna Cycle that have been great. Both are 52V; the first has been perfect for seven or so years, and I procured the second recently since it provides for 80, 90 or 100% charge. Both have fans.

I want that variable charge one for my e-trike but they have been out of the adapter forever. I need the Anderson powerpole end and just want something that clips on, not something I have to actually "wire" on. Wish they would get them back in stock again.
I love the idea of just being able to set an 80% cap and walk away.

If you need an Anderson/XT-60, you may be able to get one from Amazon or ebay.


Edit: Just checked and looks like ebay has them for about $10. I assume that you need a male Anderson to female XT-60.

So I am guessing the charger has an xt 60 female (whatever that is)? Do the adapters have to be rated for anything in particular? It just clips on the end of the existing one, no skill required? Thx

Check, but the charger has an XT-60 male AIR (and probably your battery Anderson female); can't check now, but LC should indicate. You can just plug - plug (theoretically, since I've done this before with other systems.

Apparently I need an xt60 female to barrel adapter. On amazon all I can find are male xt60 to barrel.

I've also noticed that the chargers that will stop at 80% are very hard to find currently. A workaround is to invest the time to figure out the rate at which your charger fills your battery by stopping it every half hour or even 15 min, and reading the voltage out of the charge port, (with the charger removed) with a voltmeter. There are lots of internet sites with voltage/percentage charts for various voltage batteries. Then you can make a graph of the voltage/%age on the vertical axis and time charging across the horizontal.
This graph will allow you to estimate very accurately the time required to go from whatever state of charge you are starting with to whatever %age you want. Then with a hardware store timer outlet, you can set the timer to stop the charge at that amount of time. My 48v 17ah goes from 45v to 51.7v in about 3hrs and 15min on the charger that came with it.

That's not a bad idea if I can't find the right adapter. Luna has good stock of the chargers and I do particularly like that it does slow and fast charging. I would almost always charge to 80% via the slow rate, but if I was going for a really long ride I could top it off to 100% in the morning using the fast charge function. That's a nice bit of flexibility to have.

Anker's PowerPort III Nano is the best option for charging any phone fast: It's tiny and inexpensive, and it can get a fully drained phone battery to more than 50% full in half an hour. USB-C chargers can top up phones faster than older USB-A models can, and they work with both iPhones and Android devices.

They aren't talking about charging a phone. Read the thread before commenting.

You can estimate the charge time pretty close once you have a little experience with your charger and battery. I wait until the right time to start charging based on current battery voltage and desired voltage for my ride. Easy since I always ride in the afternoon. Use a timer on the charger and set it up the night before for morning rides.
