I have kit that I installed on my 700c road bike. It's marked as 350watt which is meaningless, but I was told by the store due to law's here in Canada there is a top speed limit.
So as of now I have two battery packs, one is 10s2p from Hoover board 4A output 42v fully charged and an Xt60 connector, 36 nominal.
One quick question, what makes xt90 connectors anti spark? Cause I'm using 12awg wire on xt60s I did myself besides the single xt30 from a battery pack
The controller I have had one plug with I think 9 or 7 pins going from motor on front wheel to the controller.
I have a DC DC step down to 12v for the headlights, but I also took apart an old scooter got a 36v headlight (and horn combo) so must have a built in converter inside that. But the pack itself is really long and looks like it's 10s3p output 6A.
I have a lot of Samsung 18650 13s and 10s new BMS boards
I also have 2 5A DC step up but the best boards I have for stepping up are 2x 10A 500w adjustable voltage and current, I used JB weld to stick it to an aluminum heatsync and installed a fan. I also have a 400w step up with heatsync
I'm wondering how to do 2 different things, until I get my spot welder a better power supply and pure nickle strips instead of the nickle plated I have at the moment, I was gonna remove BMS on the 10s2p and add a 13s with more of the same mah cells I also v can't find a definite answer I know mah has to match as well as same cells in pack, but the discharge rate..... What if the cells are same brand same capacity, just one has a couple A higher max discharge rate than the others, will the BMS work and balance as long as they are the same mah cells.
So back to the main issue, is told once to hook up the step ups together, how will I set the current using that little knob. Going from 42v/36 to a 48v controller that can handle higher current.
Is there any way I can do all of this... What are my options.
With the step ups, the input current, does that get boosted as well, I only have one multimeter so I can't use it as voltmeter and ammeter at same time. I need to know how safely i can do this, but in the mean time, is there a way to join both packs I have in parallel.
What do I do? Suggestions?
