i have heard people recommending mobil 28 grease but seeing it is not sold locally i would have to order it online and i was wondering if any grease would work as long as it is synthetic. most auto parts stores carry mobil 1 synthetic and even some carry lucas red n tacky. i am going to have...

i am looking for a ups that will run on lithium so i can replace the lead acid and some of them solar generator units have ups mode where they will run the inverter if the power goes out. i would replace the battery with a bigger one that will give longer runtime since batteries are getting...

like the normal lithium batteries there are multiple chemistries does lifepo4 have multiple chemistry variants? while watching a video https://www.youtube.com/watch?v=8-Lwy42mbsw Bluetti EB3A Portable UPS Powerstation Teardown and Demo i noticed that it uses supposedly 7s2p of lifepo4 the...

i tried utahtrikes.com but they said it requires the display but it could be they never tried it or there is some switch passthrough or they want to sell kits rather than bare motors so new users can save. i tried lunacycle but they answer emails in order received so i have not heard from them...

i was wondering is there a way to use the bafang motor with just the motor, battery and throttle (no display or sensors? i saw over at lunacycle there is a bare motor (while probably intended as a replacement for broken motor) it is $350 and if there is no communication or diagnostics being...

since talking about building a trike over at https://endless-sphere.com/forums/viewtopic.php?f=3&t=102414 i just discovered a possible candidate for an etrike at worksman bikes. that may be ready made and i just have to add a second motor to make mid drive since the front wheel motor is not...

i was asking about the ebike laws. in the united states the law sais 750 watts and i have seen some youtube videos and google searches say that the more power can allow them to go faster. as well as multiple motors adding up to the total watts. so i was asking what triggers a suspicion of...

i would be using a https://www.ebikes.ca/shop/electric-bicycle-parts/stokemonkey-parts/sm-bracket.html to mount one hub for regen then i would use the cyclone motor for the power and i have the smaller bionyx motor i would mount in place of the coaster brake hub for the speed. what makes you...

i also forgot to mention that the smaller wheels would give more power for on hills if you notice modern electric wheel chair scooters have very small wheels witch allow them to go up hills easier i think the stability issue is about ratios older trikes have very narrow wheelbase and are...

instead of shifting i would use 2 separate mid drive chain drive motors fixed to 1 speed and it would set up a escher impossible staircase where trying to run both motors they would fight each other. also wiring up controllers to 1 throttle through a relay to ensure only 1 motor can run at the...

i am considering building a trike using a bike trike conversion kit like https://www.bicycledesigner.com/trike-parts/hollow-hub-trike-conversion-kit.html this will solve many problems. 1. broken kickstands as the 3rd wheel will act as a kickstand 2. stability i will be building it as a...

can the tesla battery module be charged with a hobby charger is there anything about the chemistry of the 18650 cells they use any different that would require a proprietary charging system? i know the stock oem bms may be proprietary and may not work so it would have to be replaced with either...

that is maybe what the folks of vruzend was trying to say

that's the one i had bookmarked after finding out that you had success with tying off the remaining wires at the + end of the pack. i was told by the folks of http://vruzend.com forum that it would not work as the bms units would detect the missing cell as a faulty battery and not charge. it...

the main use for the bms will be to charge and balance. i will be using hobbyking battery monitors for lvc because of their alarms. the problem was no one makes 12s bms that are not expensive. and john61ct i would have no problem with foreign if they would ship by air or if it was in mexico...
