My lipos have gotten as far as 0.040v between the highest and lowest is that acceptable? Where would I get a 12s bulk charger? According to the controllers Bluetooth app I draw 20amps at full throttle. My batterys rated capacity is 12s 32ah total that battery's are rated at 10c. And also will a identical battery other that the c rate for example. same mah different c rating last longer/more milage per AH?

That's right around I start thinking about balancing. I would probably go w/ it and ck them next charge cycle.

For 12S, you would want the Mean Well HLG-320H-48A. It's a 120 Volt input LED lighting(Like a store window display) power supply and avail. from many industrial electronics suppliers. Just Google it. It's super high quality and shuts down at the finish Voltage that you set. You will need to add a mini Voltmeter(to adj. the Voltage/Ebay) and add connectors on both ends. Make sure you get the one w/ the suffix A. It will be the last "charger" you will ever have to buy.

20 Amps is fine for Multistar. For some reason, I thought you had a BIG controller.

No, the Multistar trades a high discharge rate for smaller size, lighter weight and lower cost. For ebikes that don't need a high discharge rate, it's the best LiPoly. Although I still like the Turnigy 20 C for bricks not avail. in the Multistar.
A word about Battery Medics- A few years ago, clones started to appear. They are the Black ones and some blue ones. They are junk! Right now, I only know of one vendor for the original, high-quality Battery Medics, they are;

They are a little pricey, especially when you need 4 of them, but trust me, these are the ones you want. Plugging the balance taps onto the B.M.'s can be a little tricky, they tend to get stuck. I use 6S balance extensions(Hobby King, Ebay, Progressive RC, Hobby Partz) and file the locating nubs off to make them easier to plug-in/unplug.
So, in the end, you will need to spend some bucks to get set-up, but you will love the results, I promise.
Just don't let your cells get below 3.65 Volts :lol:
