Hello everyone . Excuse me for my English. I'm building a motorcycle and I need help with batteries. I'm using an m0909 engine and a 36-48v 300a driver I want to ride a battery multistar 6s 20a a pack of 12s 60a I would like to know what is the best way to do it
for the download I thought to use an acoustic warning but for the load I do not know which is the best option if a bms or a good charger What would you do?
12S/60,000 mAh is a very, very BIG battery pack! On my bike, that would be over 100 Kph range!
I have a pack made from 4) MultiStar 6S/10,000 mAh bricks configured 2S/2P for a 12S/20,000 mAh pack and I bulk charge using a Mean Well HLG-320-48A;
It's a 120 Volt input LED lighting(Like a store window display) power supply and avail. from many industrial electronics suppliers. That's the charger I use and it's awesome. It's fully potted, waterproof, CC/CV, dead silent(no fan) and Voltage adjustable 45V to 52V. As it approaches the set top Voltage, the Current attenuates to mili-Amps, where it will safely stay,....forever. Only a very soft "switching" can be heard. It's faster than one would think by the spec.s. Unlike a balance charger, it does not go thru switching cycles to read the cells. W/ a steady 300 Watts, it will put back approx. 5 Ah/hour.
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.
Since you have six bricks, you will need six Battery Medics to ck and balance the cells:
Here charging small 2S/1P pack
Here charging 2S/2P pck in bike with 4) Battery Medics.
