Indeed very simple, and can be accomplished by using 1 series adapter + 2 parallel adapter.

wesnewell said:You don't need series adapters at all. Just plug the positive red from one pack into the negative black from the second. The pack connectors split in half. Only other thing you need is a Y cable for the positive and a Y cable for the negative. I would recommend a couple of 2x 6s parallel balance cables to parallel the cell though. About $2 each from HK.
Don't listen to this crap. He has no idea wtf he's talking about. The LVC is perfect for 12s. At 13s it would let you over discharge the pack below 0% soc. And the idiot light led battery meter will still work, It's not very accurate in any case, As it's designed for SLA which has a much shorter voltage range. And it sure as hell won't be running 13s or higher. To keep better track of the voltage get one of these if you want to. Although with 12s, you'll never run your pack below 3% soc.friendly1uk said:Are you using lipo? If so, that is a 13s kit. If you don't use 13s the battery meter won't work. That's one ugly device to be taking up handlebar real-estate. If it didn't even work I would not be happy.
The number of cells in series presents no charging issue for you unless your trying to use radio control stuff. In which case I can only advise you to look at any of the fire threads to see why that is a bad idea.

Again... My advice is not relevant if your not building an EV pack. I thought I had made that quite clear.
wesnewell said:Going from 12s to 15s will be about 5 mph faster in speed. Only you can decide if that's what you want. Looking at 28mph to 33mph. Charging may be an issue. There's are no 15s chargers that I'm aware of, so you'd have to parallel charge the 5s packs assuming you went with 3 5s packs in series. And then you could get a 15s bms. 12s is simple. The controller LVC is perfect for 12s. Not high enough for 15s, so you'd need to monitor voltage closely as to not over discharge the pack. Just lots of options. 12s is the safest route imo. With it you'll never over discharge your lipo pack and you'll never over heat the motor. You can run it wot all day long, or until you run out of juice.
That's the problem you have. You don't know what you're talking about, and even after being told, you still don't know. Pretty much all generic controllers set the LVC the same at 10.5V per 12V sla battery. That's 42V for a 48V controller. Great for a 48V sla pack or 12s rc lipo. Terrible for 13S and above rc lipo since it will allow it to discharge below 0% soc.friendly1uk said:Oh wow Wes, have you finally got one over on me? Your sure sticking the knife in lol
So what makes this 48v kit unsuitable for 48v, what is the lvc, I need to see the facts before I congratulate you
