Asphalt Posted November 21, 2020 Share Posted November 21, 2020 I've had the Sherman for a little over a month now and the stock charger is wailing like a banshee. It's impressive that Leaperkim has been able to squeeze 5A charging in such a lightweight package, but I'm concerned about how long it will last. Has anyone experienced any failures with their charger yet? Anyone purchase a backup or alternative charger? Is the charge pin set-up compatible with Gotway/Begode? 1 Quote Link to comment Share on other sites More sharing options...
Mango Posted November 21, 2020 Share Posted November 21, 2020 I think you only need to replace the fans. I bought the Noctua on Amazon and the installation is fairly straightforward. 2 Quote Link to comment Share on other sites More sharing options...
Popular Post fbhb Posted November 21, 2020 Popular Post Share Posted November 21, 2020 (edited) I ordered a second genuine 5A charger to arrive with my Sherman and have Only used one at a time to test that both were working correctly. I think it would most probably only be on the second time of using one of mine, again just with one on it's own, whilst it was nearing 90+% charge I heard a loud "pop" - the charge cycle stopped and I quickly turned off the power supply and unplugged the power lead! I then had a sniff at the charger to see if I could detect the usual smell of burnt components and of course that tell tale odour was present! The wheel would not continue to charge with my second working charger plugged in and the display is now stuck on: "ECHAr". I have contacted my seller, who has in turn contacted Veteran for advice on the solution to this. There is a topic posted here where another owner had this very same error message on his Sherman's display straight out of the box! Interestingly enough, after opening the failed charger up, I found that there was a burnt/damaged component right next to the capacitors as well as one of the fuses on the charger's board that had blown when it failed. Following this, I decided to open up the good working charger to compare the two and found that the capacitors in the failed one were of a lower uf/size rating than the one that still works (I'm concerned that this may have been a factor and could be for others if true!). I have also passed this information and the following photos on to my seller and expect that they have also now been shown to Veteran to help with their assessment/course of action. I only got to ride the Sherman 4 times and was really loving the ride experience, huge range and all the other Sherman highlights that owners have been raving about! Fortunately for me, I have just completed All the necessary work on my S18 so at least I now have one solid and reliable New wheel to play with while I'm waiting! The 5A charger at the Top of the photo is the one that failed and also only has the smaller 150uf capacitors fitted. In this photo of the charger that failed, you can clearly see the blown component next to one of the 150uf capacitors. The second working 5A charger has 220uf capacitors fitted.

Asphalt Posted November 21, 2020 Author Share Posted November 21, 2020 Thank-you for sharing your unfortunate experience. We are very lucky to have your A-B testing data. Did you buy the second charger from your EUC dealer or AliExpress? I hope this quality fade isn't a trend with Veteran - perhaps it's YZPower trying to save money? Either way, it looks like BYC 2007 is better than BYC 2008, with the use of more highly rated capacitors. 1 Quote Link to comment Share on other sites More sharing options...

I have now been back and fixed the broken links to the 3 photos, now that I am using a dedicated photo hosting site. I will also be updating this post I created about my failed charger situation shortly to outline some changes that I have recently been made aware of, via my seller/Veteran factory to the latest supply of Veteran YZ-450 chargers: Edited April 14, 2021 by fbhb 1 Quote Link to comment Share on other sites More sharing options...

What you think about I would make a warranty claim on the charger and use one of your other chargers until you get a replacement. The fan should stay on (the charger should be generating heat at 5A), it should not cycle between on and off. 1 Quote Link to comment Share on other sites More sharing options...
fbhb Posted April 26, 2021 Share Posted April 26, 2021 Today I have updated my "Failed Leaperkim Veteran 450 5A charger" topic with the latest status on Veteran's response to this issue by updating the internals to the version of the 5A charger that they sent out to me as my Second replacement: 1 Quote Link to comment Share on other sites More sharing options...

This looks normal other euc owner from same batch have same "Strange" charger and what i read here is like normal. Anyway i use my smart(1A) or gotway original 3A charger like main charger for veteran. Sometime i use original 5A for ballancing but from my experience gotway 3A and 5A sherman do thing identicaly. Simply say original 5A i have like backup then dont worry you are not alone and charger is OK and recomended by manufacturer. Quote Link to comment Share on other sites More sharing options...
botvinik Posted June 6, 2021 Share Posted June 6, 2021 The pulsing happens to me as well. I doubt its a charger issue, more likely BMS or MB. It happens with multiple chargers. Quote Link to comment Share on other sites More sharing options...

There are two fans on the charging unit, one each on both ends. If you're looking to upgrade the fans, their dimensions are 40mm x 40mm x 10mm 12v sleeve bearing type. I bought a pair of Noctua rated at 17.9 dB and will test them out. Anyone tried this and can confirm the noctua fans are working? Looking to fan swap my charger but i'm not sure if i got the right noctua fans. Any help appreciated (: 1 Quote Link to comment Share on other sites More sharing options...
