Theebikemotor is a key components Supplier of personal electric vehicles (PEV), from electric bikes, electric scooters to electric wheelchairs. With many years’ development and production experience, our talented engineers, power wheel chair experts, DC motor and electronic controller designers, experienced assembly workforce, we are confident to provide our valued customers with the top quality products at co… [74V, 89V, and 104V @ 13Ah are available by connecting 2 batteries below in series.  37V 26Ah and 52V 26Ah are available by connecting 2 batteries below in parallel.  Instructions provided upon request.] Four hundredths of a volt is probably fine to parallel them, but I would be more worried about why the cells aren’t all the same. If they are brand new cells from the factory, they should be nearly spot on. These might be more expensive than what you paid, but I get my Samsung 25R cells from this vendor, where I know they’re genuine and straight from the factory, and all come at exactly the same voltage. Next, I added the third parallel group after the second, hot gluing it in place in the same orientation as the first, so the top of the pack alternates from positive terminals to negative terminals and back to positive terminals along the first three parallel groups. It is also possible in principle to series connect two 36V batteries to make a 72V setup,...

I just found your article, and as if it were destiny, this is exactly what I am trying to do (build a battery pack with BMS, and charge with charger). I am new to this, however, and have a question or two… If you don’t have an actual heat gun, you can use a strong hair dryer. Not all hair dryers will work, but my wife’s 2000 watt model is great. I own a real heat gun but actually prefer to use her hair dryer because it has finer controls and a wider output.  Just don’t go mess up your wife’s hair dryer! When it comes to the nickel strip you’ll be using to connect the 18650 batteries together, you will have two options: nickel-plated steel strips and pure nickel strips. Go for the pure nickel. It costs a little bit more than nickel plated steel but it has much lower resistance. That will translate into less wasted heat, more range from your battery, and a longer useful battery lifetime due to less heat damage to the cells. The sense wires generally connect to the positive of each cell group, but sometimes there is one more sense wire than parallel groups because the first sense wire is intended to connect to the negative of the first cell group, then all the subsequent sense wires connect to the positive of...

Yes, you can upgrade a GIO PB710 with a lithium battery. You just want to make sure your battery is the same voltage as the original lead acid battery and that it can handle the current demanded by the bike’s controller. I figured this would be a critical step I wouldn’t want to mess up. Thanks for the advice on using the multimeter. That’s good to know as I thought I might need to open up the controller and see which wires went where on that male xlr connection which I guess would be an option too. Thanks again! Offset packing results in a shorter pack because the parallel groups are offset by half a cell, taking up part of the space between the cells of the previous parallel group. However, this results in a somewhat wider pack as the offset parallel groups extend to each side by a quarter of a cell more than they would have in linear packing. Offset packing is handy for times where you need to fit the pack into a shorter area (such as the frame triangle) and don’t care about the width penalty. Hi Grant! I think that depends on any accessories that the battery charger may offer. I think you’d be better off getting an inverter to connect to your car battery which can output 120 Volt AC. Look for a pure...
