As I understand from Thud it's 8 packs in groups of 2 to form 4 packs and these 4 are hooked to the board to give you the desired battery. Sounds just like what I am looking for. I'll comb ES for more info and will order the board as you have suggested.
This is indeed correct if your running the 44v setups, which is the maximum you can run if using rc esc's like Castle Creations HV series escs, reason being they have a max operational voltage of 50v they won't arm at anything over i think 50.5 or 6v (
please feel free to correct me on this, i know its close to the 50v mark either way) There is a couple of options though Eddy, the way you describe is how i go about it as its easy with the lvc parallel boards to do this, others also parallel all their packs (Thud likely does it this way?) (if using 22v 5000mah packs as being discussed) we would parallel two equal number of packs, for example if we had 8 packs we would wire 2 groups of , 4x 22v packs in parallel...this would give us 22v 20ah you would then take the 2 22v 20ah 'packs' and series them up for your 44v 20ah setup...i don't think there is really a convincing argument for either method but the second is more favorable if you are reconfiguring for charging and discharging, all you do is parallel all 8 packs up and use a meanwell 24 volt charger to bulk charge all 8 packs at once heck, lipos can be charged fast as ThudSTeR mentions above, you can parallel the Meanwells up too and get some very fast charging time, high 'c' rate lipos don't break a sweat fast charging them in 40 minutes ...then though you must, re-configure back to series/parallel for discharge, only means swapping two wires but some still get it wrong and get KFF (kentucky fried fingers)
all i can say the more i study Kims bike the more impressed i am, very very very nice work kim, you and i should hang sometime...
if you dont mind, where did you get the jack drive system?
Cheers mate, if your ever in the land of West OZ drop me a line and we can definately catch up for a brew and you can try out the cruiser for yourself, i let anyone (within reason) ride it, it was built to use and abuse as well as look prurty LoL...
The reduction drive is a single stage unit made by Endless Sphere forum member (and Motorbicycling.com member also now)
Recumpence aka Matt Shumaker... he IMO (and most others) the pioneer of the use of these type motors in e-bikes, he supplies everything from the reduction drives to Astro motors, controllers, throttle, interfaces and mounting hardware, he does the lot if you have the $$$ i won't **** you it is expensive gear but its also the best money can buy, there is also a wait time on some of these items, this is Matts hobby also
not his fulltime job, i can assure you i haven't heard a bad word about Matt hes a lovely fella, and/or his products they are all top notch cnced from billet alluminium. Not sure what he charges for the single stage unit these days, its in the vacinty of US200 bucks he also does a two stage reduction and also twin motored reduction drives if your looking for near 30hp e-bike setupz :: druuuuuel:: Thanks again for the kind words mate always appreciated
