Re: Max volts for this controler

thanks I'll have to do some more reading. I wanted to buy this other controller because it is a regenerative breaking controller with cruse control! It's supposed to save 30% of the battery with regen. I tried asking them what the 48v controller had for caps and mosfets but they said 48v only use 48...

Re: Max volts for this controler

thanks for the info but someone ells on here told me that my motor can only handle 72v in burst. He has the same motor, but is that true? If that's the case I'll just run 60v max.(63) I already ordered it out of panic because it was the last one so I think I got the 48v one. These guys at the compan...

Re: Max volts for this controler

okay so I have this kit http://www.ebay.com/itm/281199914680?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 I have used 60V on it and it works fine go's about 35mph. I saw this controller http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=131098947426 I asked them how many volts can it go up to....

Re: Doc's ULTIMATE TORQUE ARMS fit most of the frame UPDATE

just wondering if these would be a good fit for my bike. I'm going to put a rear 1000w motor on here. Good news it's steal. Magnet sticks. Do you recommend pulling the dropouts apart and just welding the arms to the inside. As of right now I think I might have to pull them apart a little already. If...

Re: Max volts for this controler

diodes do not have a fixed forward bias. it changes with the current flow through the diode. so your schematic indicates a setup that does not stop the cell from overcharging if you expected the diode to prevent the voltage from climbing to 5V. right that's why I had to keep adjusting the voltage o...

Re: Max volts for this controler

okay got the meanwell mods done... All they had were 1/2k resistors and 5k pots at radio shack. So I soldered 2 resistors in series for the R25 mod and hooked the 5k pot in parallel to the R33 & R38 resistor. I wired the watt meter in the charging leads but it didn't turn on! :x Since it didn't come...

Re: Max volts for this controler

R25 mod (voltage range shift - lower) requires de-soldering 1 leg of the R25 resister and adding a 1k resister in series. R33 mod (current mod) involves adding a resister in parallel, just add a resistor to the legs of R33 & R38. I will try to test and write up the necessary values. Made a 4V 50A c...

Re: Max volts for this controler

what made you put diodes in the charging circuit. is that what you are talking about? you should not have diodes in any of the charging circuits or in the discharging circuits. but i cannot follow anything here it is so confusing. can you just draw a diagram on a napkin and take a picture so we kno...

Re: Max volts for this controler

Thanks For the reply Dr. K "DrkAngel wrote" Typically, running Diodes in parallel produces "unreliable" results. Interesting that you got things working. Yes for the most part it required constant monitoring and adjusting... The hotter the diodes were/more current draw, the more voltage drop there w...

Re: Max volts for this controler

Wow... So I found some diodes that were 1v drop instead wired three in parallel and it worked good for two days but they got really hot on batteries that were already charged to ~4.05-4.1v. Today I charged some to ~3.65v on the IMax B6. Then hooked it up to the meanwell, cranked up the voltage on th...

Re: Max volts for this controler

Haha right now I'm stuck on house arrest till the forth. So I'm just working with what I got. Once I have everything I ordered and able to go to the store for odds n ends I will be able to really ramp up testing. I plan on using my MeanWell S-150-5 to charge 60 cells at once to 4.15v.

Re: Max volts for this controler

Hi everybody. Been sitting here just reading cause I made the mistake of clipping all the cells into pairs before I realized I could have just left them 3s2p and had a bunch more charged right now. It's okay cause I'm going to bulk charge them all again once my meanwell gets in, in a couple days. Fo...

Re: Max volts for this controler

Okay so apparently I didn't notice the voltage alarms are you pick one and the last one 2-4s is out of stock. And I must have not finalized that soldering iron, so I got a second chance to think about getting a 100w one. http://www.ebay.com/itm/New-5pc-100W-Soldering-Gun-Kit-w-Case-Iron-Solder-Profe...

well gotta meanwell S-150-5 commin. $30 100 alligator clips with rubber protector $7 soldering iron, solder braided tinned copper and check this out. With the $3.00 1-8s low voltage alarm you get two other different ones for free now. the last one 2-4s QD-0345 will measure to 300v/100A! this will wo...

Re: Max volts for this controler

Thanks Ykick I'm in Minnesota by the way, upper Midwest USA. Interesting tid bit. Minnesota is the only state I have found that legally allows a 1000w motor. Other states mostly allow 750w or lower or not at all without a license. 20mph non peddle assist still applies though. I will look into heatin...

Re: Max volts for this controler

thanks for all the replies! it's nice to know I can go 15s. but after more thought I really don't need to be going more than ~28mph...cops...and where am I going to put all those cells! :shock: and in doing a lot more reading I bet out of the 336 cells I got coming...even though I only need 300 (15s...

Re: Homemade Battery Packs

hi im just getting into this and I my opinion It makes no difference which test you do first. because a bad battery (meaning no capacity) apparently can sit for a month or so showing no sings of bleed down or internal short ill call it. But a battery that has a hi capacity % can still have an intern...

Re: Max volts for this controler

Yah if I'm going to do 12s I will break them down to 4s and 5s if it's going to be a 15s. because then I can charge to 4.1. Do you recommend charging to 4.2?
