Jim Gell Posted January 22, 2016 Report Share Posted January 22, 2016 A few weeks ago someone was asking about Balqon Lithium Battery Packs in a post. I posted a brief reply, but didn't want to spend a lot of time posting on something I was still trying to figure out. I said then, and I will say again, from my experience I cannot recommend anyone buy from Balqon. I have found several posts on various forums from customers like myself who get no response from them when trying to contact them. One poster went to the business address recently and found they had moved. They are not posting their new address and phone is disconnected. Messages to CEO's ? cell phone go unreturned. I am posting today to get advice on my system repair. I was previously thinking I just needed to tweak my charging settings from solar controller and/or inverter to get the battery pack's BMS to stop tripping. Now, with both positive and negative connections to the lithium bank physically disconnected, the BMS trips off when I turn the BMS on. Cell voltages are in the "flat" normal range at 3.32V. So it appears there is a malfunctioning component in the BMS or one of the 4 solid state cell monitors. We are now using a 12V lead acid battery. Balqon should have responded to my requests to replace the BMS system, but have not. I can't say I know they are bankrupt or totally out of business for sure, but I think it is wishful thinking they are going to offer assistance in a timely manner. Therefore, I have started looking for a more pragmatic solution to get us back in business while I try to get a financial remedy through our credit card company. The House Bank BMS, cell monitors, and display products from Clean Power Auto LLC look like something I could install myself to solve my issues, The BMS would have advantage over what I have now in that I could rewire my system so that the battery would still be chargeable with low current shutdown and able to draw power off in an overcharged condition. That may not be necessary if everything works right however. Would the more technically savvy folks on here take a look at these products?

I am inclined to get it with the Bluetooth interface unless someone explains why I don't need/want it. I was thinking of ordering all the above components from them to totally replace my BMS to be sure everything was compatible. I could buy one cell monitor for under $30 with shipping and try swapping it out with each of the 4 existing monitors, one at a time. Maybe there is a better way to test the cell monitors, but it is over my head. Any thoughts on that aspect? I did see on an EV forum that Clean Power was in business at least since 2009 and are located in Tampa. Didn't find much in reviews, only a couple positive comments on the cruiser forum. Anybody have any opinions before I place an order? Jim Link to comment Share on other sites More sharing options...
