    Opening a Sur Ron X controller

    The controller has failed and the owner has a new one in-use. I wanted to take a peek inside. I removed all 8 case screws and have gently to moderately tried to separate the top plastic half from the bottom Aluminum half but noting budges. I lightly tried tapping a sharp chisel into one end...

    Is there a way with the Phaserunner and/or CA V3 software interfaces to sync the difference

    As measured at my Phaserunner battery input terminal by my in-calibration, 6.5 digit Keysight bench meter, my pack Voltage reads 49.0 and the Cycle analyst reads 48.7. Is there a way with the Phaserunner and/or CA V3 software interfaces to sync the difference?

    Li-Ion Cylindrical Cell Battery Pack Remaining Capacity v Resting Voltage Table

    Found a good Li-Ion cylindrical cell pack capacity remaining v resting voltage table from an E-bike pack rebuilder. Use the Volts Per Cell column data times number of cells in-Series to apply the table data to larger and smaller Series packs. It might be just a bit conservative - a good thing...

    128VDC Nominal, 2-6 Amp battery Charger for LFP pack

    There's a lot of threads here about real electric vehicle chargers with communication capabilities. I have a honest 113,000,000 Candle Power custom made Short Arc searchlight that I can run off of 120VAC or 130-240VDC. I have a battery pack consisting of 10 each, 4S/8400mAh LFP packs that I use...

    Fantastic Small Programmable Electronic Load and Battery Discharger

    I posted this on the RCGroups Battery forum and think it might be useful here, too. I just had my ebike batteries, LiFeP04 16S/12Ah each, upgraded to LiIon 14S/22.4 Ah each or about 1,800 usable Watt Hours. With my style of always peddling with a medium load on my legs, I can get a...

    Prodeco Battery adventure

    I run my 2014 Prodeco with two factory LFP 51.2V nominal, 12 AH packs. I custom installed the 2 battery in the triangle. I ride in Parallel and charge separately. Over the last year, I have noticed that the rear battery takes only about 40% of the total Ah used on my rides. I would expect a...

    Prodecotech 51.2V, 12 Ah LiFeP04 battery - Don't need one now

    As the title says, If someone has a good or bad 48 Volt, (51.2Volt Nominal), 16S/12 Amp Hour, LiFeP04 Prodecotech pack they would sell, I'd be interested in it. They've gone out of business as I understand it. My two are functioning fine but I'd like to prepare to rebuild them as they are 6...

    Spacing a brake rotor out 15mm?

    I want to retrofit my fat tire, 175mm dropouts ebike from a Bafang rear geared hub motor to a direct drive higher power motor for a bunch of reasons. I bought a 175mm dropout spec motor that fits the bill perfectly on the 7-speed cassette side but because it is thinner overall, the 6-bolt brake...

    I have a Fatte-Bike SGT. Mingo in the pipeline for sometime in May. It'll be their first bike delivered in an XL frame size - about 21.6". It comes with a Bafang 750 Watt Nominal geared motor. I want something in the neighborhood of 1500 Watts nominal with peaks to 2000 Watts. I found a...

    Running BMS-equipped batteries in parallel

    I'm pretty knowledgeable with things electrical and a little less knowledgeable with things electronic although I have been successful at diagnosing and repairing non-functioning switching power supplies. I'd like to run my two Prodeco 51.2 Nominal/12 Ah LiFeP04 batteries in parallel but am...

    Power Upgrade For Prodeco Oasis 28 MPH Version

    I recently got a new Prodeco Oasis, Sram 8-speed equipped beach cruiser and fitted the Prodeco Outlaw SS, 28 MPH motor in place of the 20 MPH version to get me back to near the 30 MPH I had with my E+. I also installed long, swept back handlebars and a high-rise stem – all to give me a...

    16S Capable Hobby Charger for LiFeP04

    Does anyone know of a hobby charger (able to adjust Voltage and current) that will charge a 16S LiFeP04 battery? If not, is there a "plug-n-go" type charger that has a POT on the PC board to adjust cut-off Voltage? I have high-end hobby chargers but they max out at 10S. There are others that...

    Source for minimum 3.5 to 4 Amp Hour LiFeP04 charger

    As the title says. Googling doesn't return much. I'm looking to buy a new Ebike with a 48 Volt, 12 AH LiFeP04 powered system. It comes with a measly 2 Ah charger. They want nearly $300 for a 4 Ah charger. That seems high. Would appreciate some sources for 4 Ah chargers that won't break the...

    Source for reputable 10 to 20 AH LiFePo4 pouchs

    I remember a thread from a year or so ago about a good deal on 20 AH LiFePo4 pouches and that possibly, they were fakes or sub-grades or something to that effect. Is there a source today for reputable 10 to 20 AH pouch cells and if so, are there any quality hardware kits available to put them...

    Electric motion systems ?

    I've been away for over a year and have not ridden my E+ for about that same amount of time. By chance, I was searching on the company name and the only hit was a Lipo recall for fire hazard and I discovered the company had gone belly up. Are there any threads here dealing with the company...

    Help with Cycle Analyst negative readings

    I've checked my CA stand-alone version installation at least a dozen times and it is installed as per the directions. The wires on the "controller" end of the shunt go to the Kelly controller battery input terminals. The wires on the "battery" end of the shunt go to the Lipo's thru my Kilovac...

    throttle brand identification?

    I need a wiring diagram of a 4-wire half-twist "48 system Volt" throttle with the name - as best as I can tell- "Pthe" or "dthe" molded all over the rubber grip. I tried searching for these two names on the web with no results. I think one wire is for the battery condition led's and the other...

    BMC 1000 Watt axle shaft position within the Motor Housing

    Live and learn. My bike comes with a 9-speed freewheel. The properly installed wheel within the swingarm is a full 3/8" shifted to the riders left. It runs true - it's 3/8 shifted at the hub and 3/8" shifted at the edge of the wheel. I though that by downsizing to an 8-speed freewheel, it...

    I've been tweaking my new E-Commencal Meta for about a week since I got it. I haven't ridden it yet because I want to beef up the electrical conductors and add a handlebar mounted, contactor activiating On/Off/Kill switch. Hopefully, those parts will arrive today. In the mean time, I've been...
