    cell imbalance in new hobby king lipo pack

    I did several charge discharge cycles, with balance charging it and using about 4A discharge current using 6 halogen bulbs to provide the load. The bad cell was discharging below 3.4V when the others would only be down a couple tenths from wherever I started, and it was getting worse each time...

    cell imbalance in new hobby king lipo pack

    I'll post back when I have results. I will do a normal balance charge to full and then will be storing them for a little while before I am ready to use. Will monitor periodically. Without doing anything else, the one cell was down another few hundredths of a V, while the others remain strong...

    Hobbyking 6S BMS

    Yes to all. Note that the battery medics (BM's) referenced in this thread are not the same as a bms (battery management system), so careful not to confuse the two when reading. More often than not, when someone says bms/BMS, they are referring to the management sysstem. But the battery medics...

    cell imbalance in new hobby king lipo pack

    Ok, good to hear that I am over-reacting. I had just read thru the Neptronix lipo tutorial (again) and it said early on that a difference over 0.10 volts was a bad sign, so I was feeling concerned. Whenever I buy something new, I want it to work perfectly at the start, so this is part of my...

    cell imbalance in new hobby king lipo pack

    I received my Multistar lipos from hobbyking the other day and had tested out all cells in each pack over the weekend. Out of the box, everything was at 3.75V +/- 0.05 except for one pack where one cell was at 3.6V. Based on what I read in Neptronix's Lipo tutorial, I felt like this is...

    Hobbyking 6S BMS

    Thanks for the feedback, Amberwolf. One other thing I thought about and was wondering if it would help keep cells balanced is to parallel individual cells together across the strings using the balance cables and just leave them that way all the time. With the right connections, the cells in...

    Hobbyking 6S BMS

    Hi Motomech, I've noticed several of your posts on the topic of bulk charging lipos using the battery medics as a cell monitor and balancer. I was wondering if you feel it's important to have one attached to every pack throughout the charge. As an alternative, I was thinking it would serve...

    planning new ebike build - several questions

    Hi Scooterman, Happy New Year to you! Thank you for sending the data when running at different power levels on your Mac. This is helpful. I had looked at your build page before and like the setup a lot. I had actually considered the Mac motor for my build initially. However, I asked EM3EV...

    Newbie with an ebike

    It's a nice looking set up. I'm looking to do something similar. What is the donor bike you used?

    planning new ebike build - several questions

    I've been researching a bit more on the frames and suspension and associated costs. You really hit the nail on the head with your comment: "Those of us that want good performance always find out that it costs more than what we wanted and at first thought." The cost for the ebike frame and...

    planning new ebike build - several questions

    Thanks for the info, Scooterman. My fork is a Manitou Minute 29er with 100 mm travel and it is both tapered and through axle. It sounds like what you described might be a good option for me. I'll be doing some more research about the 29er fork with standard 26" frame and will have a look at...

    planning new ebike build - several questions

    Good comments about the frame that I hadn't thought about. Thanks! I did see mention of the Monocog frame cracking with hard riding but I never considered that this would be likely on an ebike or that it could equate to injury other than to the bike itself. I figured a solid re-weld could...

    planning new ebike build - several questions

    Greetings! I've been reading up on ebikes and options available recently but I feel like I've been drinking from the fire hose and have only scratched the surface on all the information in ES... After my initial research I believe I have a starting plan for my ebike build and have some time...

    Having trouble deciding what to use on my ebike build

    Hey PizzaWizard, I am planning to do a build very similar to yours and looking at many of the same components. I was wondering about the wheel choice you made for the 29er. You showed the 700c wheel in your list of items, but initially you had mentioned the 29" version. I see the cost is...

    Analysis of regen on an ebike

    Can anyone provide more input on this? Thanks, Tim

    Analysis of regen on an ebike

    I came across this post and was really interested in the analysis. One thing I don't understand is that the maximum energy regenerated is only 50% of the energy available from the initial kinetic energy. I'm not an electrical engineer, so I didn't follow the argument for why it would be...
