72v, 300 watts, and flawless performance!
I have had this charger since July 2016, and have used it for charging the battery I bought from Luna at the same time, and have used it on a daily basis pulling a 100 lb bicycle trailer to work. I love the easy to use 3 position switch for 80/90 or 100% charging, and use it for 80% 99% of the time to extend the battery's life.
The battery charge has worked flawlessly, and from the beginning I was impressed by the quality of the aluminum case and fans that aren't typically included with a charger bought with battery combo from most sellers, the industry standard has been improved upon by Luna significantly, and at a reasonable price.
I would recommend these chargers, and would not settle for any less!
Good first impressions but...
The charger works fine, no problems there. Fan is a bit loud but the unit stays barely warm through the charge. That's nice.
I'm not giving it 5 stars because:
- 3A-5A charge selector is missing on my unit for some reason. It's not what is shown on the product page pictures. The description only says 3A, I know, but he online manual also references the switch. At least information is inconsistent and creates confusion.
- Lacks a printed manual. There's one online, but a user shouldn't rely on an available online computer for reference. At least there should be a pdf file for download. At least you should include some warnings on what not to do on your initial use. Like "Plug charger before battery". Or "turn off charge to switch charge level cutoff" since it seems you can't do this "on the fly".
- On a similar note, labeling of switches and lights on the charger itself is incomplete and is not easy to read. You have to go online to figure out that 80% charge is all the way up, 90% in the middle and 100% fully down. Also LED1 and LED2 are not very self explanatory, you have to read the label to know what you are looking at.
We'll see how it holds.
