    EGO 56V 4Ah lawn tool Lithium Ion battery

    All, I disassembled my own 2.0Ah 56v pack to see what's inside. The assembly is very nice, the BMS is fully potted and there appears to be a secondary board that talks to teh charger and the device it is powering. There does not appear to be an actual pack disconnect device such as a MOSFET...

    2 Speed Xiongda hubmotor

    Is the lishui controller much larger than the KT? What are the dimensions of lishui?

    2 Speed Xiongda hubmotor

    After seeing a picture of a liushi controller I can confirm I DO NOT have a liushi, must be KT controller. Sorry for the confusion.

    2 Speed Xiongda hubmotor

    All of my controllers have been lishui. The motors are specified for 700C wheel size when ordered. The freewheel is only 5 speed Reported speed on display is accurate and correct XD has not sent me any new displays (they are LCD-3 type) If I start up a hill in Low and switch to auto mid-hill it...

    2 Speed Xiongda hubmotor

    I have purchased 2 of these motors for 700C road bike application. First of all the motors appear very high quality, they came with sine wave controllers and they operate quietly. I am having 1 very bad problem which even xingda cannot figure out. That is when in AUTOmatic mode the motor...

    9FET Infineion feels faster than 18FET???!

    I built the bikes, I've built many! Controllers are Lyen versions. Cycle analyst reports peak amps on the 9 get as 85-90A, on the 18fet it's 75-80A. Block timing (over current delay) is. 5s on both. Both have the same bullet connectors, battery, etc. I checked amperage reported on the cycle...

    9FET Infineion feels faster than 18FET???!

    How is this possible: 2 bikes, same motor (xlyte 4065), same battery (72V10Ah), one has a 9FET infineon, the other a 18FET. The 9FET is set to: Battery limit: 49.6A Phase limit: 125A Overcurrent delay: 0.5S The 18FET is set to: Battery limit: 74.8A Phase limit: 189.4A Overcurrent delay: 0.5S...

    Comparing Motor Case Temp to Internal Temp

    Is there any general temperature range to compare the outside case of the motor and what the internal should approximately be? Reason being is I am seeing higher temps reported on my CA than I was expecting. I am running a crystalyte 4065 on 72V LiFe and max 50A. Continuous watts at speed is...

    Infineon R12 regen voltage mod abnormality?

    I got a reply from Lyen that he has already done the resistor mod, DOH!

    Infineon R12 regen voltage mod abnormality?

    I use a fluke all day at work. I've tried another meter and it too reports 894 ohms.

    Infineon R12 regen voltage mod abnormality?

    I was just going to modify my R12 resistor from 1.2K to 1K to increase regen above 75V (https://sites.google.com/site/shelbyelectro/controllers-and-electronics/controllers/infenion-high-voltage-regen-r12-mod). When I opened my MCU I probed R12 with my fluke dmm and it measured .894K ohms? Is...

    Cycle Analyst V3 preview and first beta release

    Telektik, Thank you so much for showing me the light (so to speak ha)! I studied your calculations and how you came up with them and understand fully what's going on here. I've never dealt with different types of temperature sensors (PTC, NTC, LM35 etc) until this so it's been a bit of a...

    Cycle Analyst V3 preview and first beta release

    Through some crazy calculations I don't even know how I came up with, I entered: 1.20V for temp unit, and 100 degrees/volt and the CA is displaying the correct voltage. Does that sound ok?

    Cycle Analyst V3 preview and first beta release

    Thank you for the most excellent reply! I have measured the resistance between ground and the thermistors output, at 25C I am getting a reading of 1.968k Ohm. Does this mean it is really a 2K NTC thermistor? I am so upset over this with crystalyte, the info they've told me is its the KTY81-210...

    Bump Here are pictures of the reading I am getting. Bike is cold at room temp which is 25C. Why is it so far off?

    Cycle Analyst V3 preview and first beta release

    So previously I had an LM35 temp sensor on a MAC motor so I performed hte LM35 sensor mod to my CAV3 as seen here: http://www.endless-sphere.com/forums/viewtopic.php?f=4&t=37964&start=270#p573801 Now I am running a crystalyte 4065 which has a 10K NTC thermistor. I started to convert my CAV3...

    Torque Arm for Giant Anthem rear hub motor?

    I cannot weld but there are plenty of welding shops in the area. The MTB dropouts are aluminum so Doc's steel torque arms can't be welded on.

    Torque Arm for Giant Anthem rear hub motor?

    I am trying to source a good torque arm for a giant anthem MTB for a rear hub motor. The motor is a crystalyte HS4065R so it should be a bit beefy. I wanted to use the caliper mount, but the caliper mounting isn't IS compatible, but "post mount" style like on front forks. The rear brake section...
