    cheapest watt meter yet?

    Received mine. After working to connect plugs for 2 hours I first hooked it up to the battery pack, fired up, cool. Finished the harness to hook to the bike. Decided to use it to test charging the battery. I hooked it first to the charger, set at max 50.3 volts, fired up, but the display was...

    Anyone have any experience with these?

    I have the BM12S LiPo monitor. The first one died, the vendor promptly replaced it. The second one works but there are some problems. Some cell voltages are off either Hi or Low. Knowing this I can take this in consideration. Cannot see in the sun light unless shaded. Cell low voltage alarm is...

    Worst Crashes/Accidents/Failures etc on E-bike: Bring pics

    Sorry no pics. On the 15th was coming back from the beach on a dirt road I have not been on before. The last thing I remember this is a good dirt road I'll have to take it again. The next thing I am waking up in the ER while there taking more blood. Someone found me unconcious in the middle of...

    Show off your lipo setup!

    Hi, Just getting around to posting my LiPo pack. It is a 12s6p pack. 44volt 30 amp hours with a BM12 battery monitor in a Topeak bag. It is removable from the bike. The Battery Pack is made with Hobby king Turnigy 6s 5AH 20c packs. 4 of them are 25c packs as HK ran out of 20c packs. Each 6s...

    Lab supply as lipo charger?

    I want another one too. Added to my wish list, Bookmarked the seller.t The display seems accurate. I use anderson connectors on my battery pack so when I bulk charge there is no possibility of mixing polarity, but have to double check my self when I do cell balancing to make sure I do not...

    Lab supply as lipo charger?

    I have this supply and it is great for bulk charging my 12s 30 AH LiPo pack. Mine maxes out at 50.3 volts and 21.3 Amps. Beaware of a few things. It is not polarity protected, so if you hook up any battery reversed it will blow it out. Second fan speed is dependent on voltage setting so at low...

    UPS 3day for Batteries from China

    For 2 packs 20c from China with UPS 3 day air is about $130. For 2 packs 25c from USA by priority mail is about S137. As I mentioned before can only ship by UPS only 2 packs at a time due to weight restrictions. I have decided to wait 2 weeks for my next payday and order 4 packs of the 25c from...

    UPS 3day for Batteries from China

    Hi, a couple of questions. Hobby King is now out of the Turnigy 20C 6S 5000mah lipo batteries in their US warehouse. They still have them in the China warehouse. I do not want to wait a month to get these batteries as i did when I ordered some connectors. Tracking was useless. Stuck in New York...

    Here is a letter I had to send out tonight. (long) (UPDATE!)

    With the bike I posted the pictures of earlier in the thread, had an amusing encounter with the police. I was riding around the City Park when a motorcycle cop stopped me. Saw the bike and asked me all kinds of questions about electric bikes an thought my bike was really cool. So cool he wanted...

    Hi all, Wilderness Energy web site seems to be gone. Have checked for 4 days. Always comes up Domain not found. Have a BD24 motor I was going to order brushes for. Found the entire mounting plate and brushes at Javacycles. Might be handy if the brush holders go bad. Plan to measure new brush and...

    Inexpensive Load Tester

    This is the cheapest I found on a quick search. http://www.harborfreight.com/500-amp-carbon-pile-load-tester-91129.html. You have an adjustible load. I was thinking you can check voltage sag under test load of any amps you want. Years ago I repaired and calibrated automotive test equipment. This...

    BMS battery 900w charger questions

    It was mentioned in doctorbass's thread http://www.endless-sphere.com/forums/viewtopic.php?f=14&t=29096&start=15. The guy hasn't said if he followed through, but it looks fully adjustible, volts, cc amps, cutoff, etc. Ray

    Turnigy Dual 6S Charger Series Charging

    Hi Dogman, your reply is why If I wrote an incident report I had someone else proof read it as it made a perfect sense to me but not to the person reading it. Yes in your senario I would have 2 sets of 2 packs in parallel then in series. Basically be running 44 volts with 10 amp hours. To...

    Turnigy Dual 6S Charger Series Charging

    Thanks for the replys, I thought so. Now can I leave the balance connectors plugged in while I run the bike with the power connectors disconnected or do I also have to unplug them also? And/Or leave everything connected in series while the charger is off and when I go to charge simply...

    Enclosure for Charging Large Lipo Pack

    The pack I am building will be on another thread when it gets close to completion (estimate a month) and I hope people will like my ideas. I guess I am asking if this is a viable idea in case catastrophic failure happens for whatever reason? The cost is small compared to a garage or house or...

    Enclosure for Charging Large Lipo Pack

    Maybe I am being paronoid. The point about the fan is good, I will have to think about that. The practices factor I totally agree with and will diligently do. I am fairly sure if the pact does go all 12 to 20 pacts will follow. Lots of gas, soot, heat and flame. Will be using this pact, when...

    House Burned down from RC LiPo Fire

    From his set up for containing, in case something happens, has what I think might be flaw? Doesn't LiPos when they puff and eventually popp spew hydrogen gas? If so, mixing with air creats an air bomb which very few enclosers could with-stand. Either have a low volume containment or some sort of...

    Hit my first pedestrian today...

    Longtime member, just don't post much. Anyway, when I lived in Denver, my fault, going too fast on the sidewalk next to Colfax ave 1 block from home. Two guys walked out of a bar in front of me. It was either hit them or the parked car. I chose the car. Of course it was their car. Put a little...

    Schwinn Stingray Controller

    Hi people, received a reply from High Tech Bikes. They said they must of sent me their new controller. You can use it sensored or swensorless. For sensorless just unplugg the sensor connector and it will go sensorless. Ithought that is a neat idea. Ray
