Hello,
I am working with some A123 26650 Cells and I am trying to find a high quality robust charger. I was using this one here: http://www.batteryspace.com/Smart-Charger-5.0A-for-38.4V-LiFePO4-Battery-Pack-110-240V.aspx I thought that it was a high quality charger, but it ended up catching fire/smoking profusely during a charge. It also didn't seem to be ver efficient as it required a fan and got very warm.
I have been trying to find a nice enclosed switching supply but I can't find anything off the shelf that will work. This one from mean well is close:https://www.sager.com/_resources/pdfs/product/GC330.pdf However, it is only available in a 40.8v version and a 54.4v. My system needs 43.2v minimum to charge and balance and Mean Well has a MOQ of 200 for modifications. So I have two options, either buy one of those chargers, open it up and look for the resistors that determine voltage and current and change them to suit my needs, or find a way to charge the cells with the 54.4v version. I think Boosted is actually doing just that on their V2 as they are using 12 of the 26650's and a 54v charger. Any thoughts on how that is done?
Cheers!
