No matter the adventure that you have planned, we’ve got the best equipment to enhance your experience. You may need a sleeping pad for overnight camping or a dry bag to keep your gear safe. If you’re heading out for a weekend in the woods, we’ll help you find the best products to take on your journey. Outdoor Gear To find the best outdoor gear, we assembled a list of products, taking a close look at the factors that would make each great for a camping trip or other outdoor adventure, including each product’s overall size, weight, and durability.Presumably IF the battery is rejuvenated then the metal is dissolved back into suspension form in the electrolyte and the risk of fire is back to near normal for the battery. If such a special charger is needed can you provide the name of it and a link to one? Can the original bicycle charger be used? I suspect a constant current special type charger maybe needed with adjustable amperage output. Still, I do like to know how is it possible to rejuvenate this battery. If I do charge this battery it will be on concrete and away from anything flammable. I understand that the risk of fire may increase due to Metal Precipitation in the Electrolyte Solution in a deeply discharged battery due to possible short formation as shown in picture 4. Please advise if the way the battery voltage is measured this time round is the correct way and what you make of the numbers obtained. I remeasured the battery voltages using the method in picture 2 below and got the measurements shown in picture 3. Which I now think was not the correct way to measure the voltage. The original way the battery voltage was measured was as shown below in the first picture. Some people will try to recover a fully discharged cell though, but they're playing with fire. These can link up if the cell is rechargd, and cause an internal short circuit that will overheat the cell and start a fire. Metal precipitates form in the electrolyte. When a cell is discharged below its rated limit, It is ruined. You can go lower than 3 volts as the manufacturere's limit is lower, usually 2.2 - 2.5 volts, but never lower than the rated limit. The safe range of a lithium cell is between 3 and 4.2Volts. What you want to see is 3 to 4 volts across those cells. If so, then your voltage data says the battery is dead, with just a few tenths of a volt across each cell as you go right to left. Then you measured each island of metal going to the positive lead on the left side. Just to be sure, we understand your data, you kept the black probe on the most negative end of the battery cells on the right side of the pictures, not on the negative lead of the battery. How can I disassemble this further in a way that I can reassemble it later? The individual battery cells are not only welded to the strips on each side of them but are also glued to the battery holder. What are my options at this point? How can I check this battery further? Any link to video or text that would explain what needs to be done and how to test the battery would be useful. Can this be verified?Ĭan this BMS be reused if this temp sensor has gone bad? The one that came undone still has its 2 wires attached to each other, I think what came off was only the protection and the temp sensor itself is good. I think these are temp sensors and there were 3 of them. I took out anything that was glued to the battery and while doing that one of a pair of wires that was glued to the case of the batteries came undone as shown in the pictures. Once the battery was out I checked the voltage at the BMS. I opened the battery after it was out but had to heat the case to soften the double sided glue inside to be able to open the 2 halves of the battery. The second time I opened the lower compartment of the bicycle's frame and yanked on the cables the battery gradually came out. I thought of charging this one and then connecting it to the charge port of the iZip bike to see if the voltage of the iZip battery gets high enough for the charger to start charging. Is there anyway to try to get the battery charged without taking it out? I have another used weak battery 37V 14A. Is the charger dependent on a minimum voltage at the battery to turn on? The charger won't turn on and I suspect it is due to not enough voltage at the battery. The bike must have sat for a long time (at least 6 months but probably more than a year). The battery has about zero voltage measured at the charging port. I thought there surely must be an easier way to access it. Tried to access the battery from below the frame tube as shown in the pictures but not possible from what I see, unless everything is disconnected. If you can identify the model from the pictures please do so. How can the battery on iZip Metro be taken out?Īctually I am not sure of the model of the bike so pictures are enclosed.
