    3/16" tab punch

    They make spot weld cutters . They are used to remove a spot weld and make a good round hole. That may work for you.

    Samsung EV batteries Fiat BMW

    I see no real advantage of this graphite anode battery over your LTO pack. It is just a little bit lighter than LTO but not by much and none of the advantages that LTO offers.

    Samsung EV batteries Fiat BMW

    As you already know If you charge 5.1kw in the pack assuming you started at cutoff you will never get 5.6kw. You may have wires and shunts that are making your reading seem 9% off. Did you verify your test equipment like the shunt and any voltage drops on wires? Best of luck with your new batteries!

    Simple Shunt Top Balancer

    One member I know of sells a pc board to do what you want. I would look in the for sale area if interested.

    advise for opto-coupler

    I am doing low voltage cell alarm at around 1.7vdc per cell. I use LTO cells that you can charge very quick. I will be charging around 18amps 48vdc. Worse case maybe 1.5 hr with a 25 a/hr pack. A well top balanced pack will not have a problem going over voltage on a cell on the tests I have...

    Kreisel - Water Cooled Battery Packs

    You may want to look into LTO batteries. They charge in 8 min. Just remember that is a 50 amp power supply for a 10 amp/hr battery. A 10 amp supply charges 10 amp/hr battery in one hour and they really don't generate much heat. If you need more information or planning to buy, we have a member of...

    If you need something that just works ,buying new or good used parts are your best options and in the long run it maybe cheaper.

    48 mpg in the 2013 Kia Forte!

    They used a wide band O2 sensor to set AF ratio. I made a meter from that sensor and it works great.

    One of the non western medical treatment is St Johns wort and/or seeping oat straw in a tea. I don't think AW wants to use it anyway, so I will leave it at that.

    I agree work is key. Sitting around thinking about things will only make things worse. You work at a place with people that have pets. Someone may have a place to rent that may let you have a pet. If you are not at work full time you maybe missing a chance to find a place. Like what was said...

    AW we have had rain every day for a week. You are very lucky your stuff is still dry. If you had it here most of the soot would be washed off. I see things from the past out there. TEK scope cart and old CRTs. None of them are light. With a back that can remind me I am not 18 yrs old, mine...

    Maybe the fets on the other board are good and you can move them over. Sorry you had this happen.

    Bionx 350 rear axle broke

    The BIONX like PAS is now being sold by others. If you don't need PAS the price difference is huge. The bike shop said over $2000 plus installation and my kit was $550 for a 500w motor. I think the CA and PAS kit is around $350. It may have cosmetic differences but my kit delivers more power.

    O2Micro OZ890 Based BMS Units

    You are using the BMS battery programmer? I2C systems I have used in the past can loose connection. Because of this problem I am don't know if the system would be robust enough to connect to a microcontroller and display the battery condition reliably. I am happy with the BMS and it works...

    RESOLVED! ES member fell very ill & is working this out :)

    I don't know how you will recover the money. I have seen good intentions go sour on projects like this. I hate to say it I never seen the money get recovered. I have been burned on deals but fortunately very little money was involved. Wish you the best of luck.

    2WD Semi-Recumbent Recycled-Parts Cargo eBike: "CrazyBike2"

    You mean your controller is getting warm not your motor? If you motor is getting warm you may have something rubbing , bad bearing , brake hanging up. I run 500w motor an it never gets warm running a cargo bike. It sounds like your drawing lots of current and running into the current limit. This...

    The vacuum tube 2kv transmitter units will kill. I sized a cover bleeder resistor wrong and opened the cover and it sounded like a 22 going off in the house.

    O2Micro OZ890 Based BMS Units

    I think you have limited options and none of them sound that great. If you want to stay with this BMS order a few boards and a programmer and hope the programmer does what you want it to do. If you have limited money use another BMS or just order another BMS like the one you have. If you don't...

    AW enjoy the long weekend. I am doing the cleaning this weekend. I am cleaning the garage. With the extra stress your under keep an eye on your health. All you need now is getting sick. You are very lucky to have Bill as a friend.

    The animal shelter people may know people that have trucks. Just tell them the money goes to the shelter. You get rid of the junk and the shelter gets some badly needed funds. I wish I had a better idea but sometimes their are not many good solutions.

    O2Micro OZ890 Based BMS Units

    This is incorrect I have seen the voltage bleed down and the charger turn on and top off the battery. The one I have works great but again it maybe programed different.

    Homemade Battery Packs

    When you ordered the BMS what settings did they program? Did you order the higher current option?

    I understand the sorting thing. I built a shed last year and tore down the old one and put all the stuff from the old shed into the garage for the winter and I am sorting that mess now. Then it all goes into my new shed. Keep up the good work.

    I know this sounds strange but I would get rid of the junk first in this case. It does 2 things. It looks like your getting something done and you feel like you are not spinning your wheels on this. You get some money in and it don't draw attention to your stuff you are keeping and you have more...
