Selling a 48v 6amp wate battery charger. I drilled a hole in the case so voltage can be adjusted to a lower voltage. Battery charger is new only plugged in to verify it works. $60.00 shipped in the USA. Buyer pays paypal fees.

this is jbd new bms it's a 24 or 48v that has automatic detection of strings. I have some on order just not sure how they work yet. They were just released.

North bay. I live in rohnert park and work in navato.

To be honest with you Will I don't trust any of your reviews where the company sends you a battery to review. Especially if they are a direct china supplier. They can easily send you a battery that is assembled with care and pride that well exceeds capacity and then sell complete junk. You are...

This is amy zheng website. It is not part of alibaba but is part of docan. https://www.docanpower.com/index.php?route=common/home

I just ordered one of docans 12v prebuilt batteries. I looked at the part number for the bms and it was the 100ah jbd that CAN be series connected or paralleled. This was just in the one I bought, hopefully they continue to use that bms. This is something we will never no unless they put the...

I just wanted to share my thoughts and what I have found on the prebuilt 12v battery purchased @Amy Zheng from docans houston warehouse. The battery arrived in good condition and was packaged very well and was at 48% soc. When charging the battery I did find the cells were out of ballance this...

Thanks for the replies. Some of my concerns are the voltage being to low and possibly damage from the vibrations. I am meeting with a guy on Monday to look at his stereo and see how many amps he is pulling from the battery. I guess he just needs to try it and see how it goes.

I see that most people are using LTO for the batteries. Rumor has it that a new company has bought yinlong and the supply for good lto is hard to come by. Just more curios about the prismatic cells and if they would work in the car audio systems.

Does anyone no how well the prismatic cells would work in a car audio system. I have had a few people ask me and I don't really have a answer for them. Seems the yinlong LTO are the most popular due to being able to achieve a higher voltage. Also seems they are not using a bms on the LTO builds...

This question seems to be asked alot lately. I found this to be the best option. Drill and tap the heat sink with a m3 and use 3/4 in L brackets. This is what I do to all the jbd 200 amp. Picture is without the L brackets.

I just drill and tap the heat sink with a m3 and use 3/4 in L brackets. I don't have the L bracket on this one but you get the idea.

I have 27 empty battery boxes I am just trying sale for what I paid for them. The cost of shipping these boxes just doesn't make it worth selling them. If you live in California, bay area and are able to pick them up this is a great deal. $55.00 each.

The 200amp one in picture 3 is by far the better bms as long as your use is only 12v. That bms can't be series connected. It may be overkill for your application but that's OK. You can get it with or without the heater function. The massive heat sink on the back is also a big bonus. You can...

So I get the series connection but how would a bms even no if it was hooked up in parallel?
