    Hyperion EOS 1420i NET3 14s Balance Charger...

    Blackssr: Interesting you got a 3ft balance harness to work. I could not get the balancing wires longer than 12 inches without getting a connection error. Do you have a secret to getting the long balance wires to work? Barry

    I drove a Volt tonight.....

    My wife and I drove a Leaf last month. We were also impressed with the car. You could hardly tell it was electric. I expect to take delivery of a new Leaf on 11-28-11. I'm thinking of selling the batteries on ES and buying two Leaf's. Barry

    First lipo pack, 5s Turnigy?

    Kurt: The money I make on my part time job and my social security check are mine. I reserve the right to spend this money as I see fit. This causes a little friction, but not to bad. I also ordered her a Nissan Leaf which will arrive in November. That should make her happy, I hope. Barry

    First lipo pack, 5s Turnigy?

    Be careful, my wife found out what I was spending on e-bikes and I had to get a part time job after nine years of retirement. Barry

    Why did you get into electric bikes?

    I got interested in E-Bikes by chance. I originally started researching converting a gas car to electric. I was a little frustrated that there are no viable electric cars available to the public at that time. After a little research, I decided it would be wise to first acquire some electrical...

    Good and Reliable Bms

    darkshirikens, My pile of broken BMS’s is five deep. Do your self a favor and charge and balance your headway pack with a Hyperion 1420I charger. Break your 72v pack down into two 36v packs for charging and series them together for discharge. Don’t discharge your pack more than 80% and...

    What gauge (AWG) are the hall wires for a Crystalyte?

    Floont, The smaller the better in my opinion. I tried using 24 awg to repair my X5 but the wires were to big at the point were I soldered them to the hall sensors. I went with 28 awg and soldered the three positive and three negative wires together after they exited the motor. I used shrink...

    Problem with 5303 Crystalyte motor

    Solved my problem. It was the hall sensors. I replaced the sensors for the second time with 40A sensors. This time it did the trick, the motor runs like new and I'm back on the road. Barry

    Power Supply Q's for Hyperion 1420i Charger

    EBJ: One inexpensive way to go is buy used power supplies from http://www.dougdeals.com. I purchased a 24v 500watt used meanwell power supplies for around $50.00. They stand behind their products. The first power supply they sent me stoped working after a couple of hours. They replaced the...

    Problem with 5303 Crystalyte motor

    Back to work trouble shooting my motor problem. To eliminate the controller and throttle as the problem I removed a good controller from my working bike and installed it in my broken bike. This took a lot of effort since none of the connections on the two controllers are the same. I thought...

    Problem with 5303 Crystalyte motor

    John: Just tried it without the three speed switch and CA, no help. I know it is not the throttle since I tried it with a known good throttle. However I will check the volts coming from the controller to the throttle to see if that is the problem. I have to put this problem aside right...

    Problem with 5303 Crystalyte motor

    mvly, Thanks for the tip. I checked for shorts when I had the motor open to install the hall sensors. I just checked for shorts again based on your advice. I didn’t detect a short between the halls and the phase wires at the motor or at the controller. Looks like I will have to keep on...

    Problem with 5303 Crystalyte motor

    I need a little help diagnosing a problem with a Crystalyte 5303 motor and a 72v 40 amp Crystalyte controller. The bike stopped working. When I press the throttle nothing happens. The CA showed that the controller is pulling amps when the throttle is pressed, however the motor does not run...

    FiveThumbs up for RCDumbThumbs. com "Hyperion 1420i Charger" I was impressed with RC DumbThumbs.com when I purchased my Hyperion 1420I charger from them back in April of this year. I placed my order online in the afternoon, and they shipped it that same day. I received the charger two days...

    Comradegerry thnaks for the information. My original plan was to start the Grayborg project this winter when I have more time. Also, most of the parts for this build are going to be donated from Turbo Lance my current EV transportation. Transferring parts especially the batteries would cause...

    Grayborg builders: Need a little help from someone who has installed the bottom bracket and the swing arms. Can you tell me the thread size for the bottom bracket and also the threading for the two bolts that will hold the swing arms together. Thanks in advance. Barry

    I received my Grayborg frame yesterday, thank you Accountant. It took 21 day to get to South Carolina USA from Croatia. Not bad for half way around the world. When I picked the package up from the post office I was horrified. The package looked like it had been through a meat grinder. I...

    Power Supply Q's for Hyperion 1420i Charger

    I use a Meanwell SE-450-24, 450W 24V Power Supply to power the Hyperion 1420i. EPbuddy.com was the vendor. The 1420i is used to charge a 36v 20Ah Headway pack. The SE-450 allows a max charge of 7 amps. The charger is a little finicky at times but is the best solution I have found to get a...

    Hyperion EOS 1420i NET3 14s Balance Charger...

    For the past three months I have been using a Hyperion 1420i to charger two 36v20Ah Headway packs. I use the two packs in series to power my bike. The charger works great. The 1420i is the best solution I have found to balancing and charging a headway pack. I would like to expand my...

    Resistance was futile, I ordered my frame from the Accountant last week. My plan is to transfer all my parts from my tidelforce build to the Grayborg frame. I will be using a 72v 20Ah headway pack so I know they will fit. My only concern at this point is can I get a kick stand that will...

    72V 20Ah Headway pack

    $16.66 a cell is not bad price for headway 10AH cells. Unfortunately I just received a shipment from China. Somehow all discussions about Headway cells turn into BMS and balancing problems. I have gone through 4 BMS’s, 2 bulk charges and 12 single cell chargers over the past two years...
