Replacement Charger for 2018 Quick-E+?

[pullenj]

I'm looking for a second charger for my Quick-E to keep at work. I know that I can get one through my LBS ( ~$200, i think ) but I'm wondering if there are any other ones out there that might be worth looking into. I know there are a ton on amazon and other sites but I'm afraid that I will get what I pay for with some of those. Anyone have experience with any non OEM chargers? Thanks!

other than the potentially suspect quality of dirt cheap chargers from Alibaba, etc. … the biggest issue might be the connector which is not the standard coaxial LV connector a lot of batteries use

I purchased a Lunacycle Advanced charger for my FLX e bike. I swapped out the cable from my OEM charger. I am impressed with the quality and features of this Luna Advanced charger. It easily lets me choose the charging rate (1 to 5 amps) and the charging limit (80-90-100%). Now I can safely and easily charge my battery slowly at 1 amp to 80% level.

I also am considering the Lunacycle Advanced Charger for a second charger to pair with the OEM (~4 amp) charger (one for home, one for the office); and seems like it might be better for the battery longevity. According to my LBS, the 2020's are going to ship with the Giant Smart Charger at a lower current, so maybe they think so, too. Guy at my LBS thinks this is a Bad Thing (because charging takes longer), but for my purpose it would mainly be charging overnight at home, anyway, so 1-2 amps is probably enough and presumably better for the battery (not sure, Luna seems to think so). Meanwhile I'll just charge at home every couple of commutes and manually try to catch it when it gets into the in 80-100% range (last LED).

I have the Giant Road E+. I’m also looking for a spare charger for the office. Can anyone confirm that the Lunacycle charger referenced in this thread works?

I too am interested in this. My Smart Charger is dead and I am feeling like Giant warranty will take too long (I've already tested another friend's charger... his works).

I contacted Luna and asked about compatibility (sent an image of the Giant connector) and here's what they said:

Sorry friend we do not have instructions on how to convert to this connector.
I assume there's a positive and a negative on that and you'll have to find them.
You will need a multimeter tool to determine polarity and then the charger
also has a positive and negative wires. Once you know which is which you
would solder the positive to the positive and negative to negative wires.
Make sure they're insulated before you pug the charger to the wall.

I take it it's not turnkey and I'd have to rip out the connector from the charger module. But the PROBLEM is that there are 5 pins, not 2. I read in another forum that Pin 2 and 3 are for communication, and therefore, converting another charger to work on the Giant requires a fair bit of additional engineering that I HOPE someone has already done (and which I am interested to know).

Why you don't just order a new Smart Charger at nearest Giant LBS? Hopefully you don't want a battery fire @microfiz?

Just looking at options, sir. =)
