    Looking for someone to repair a ebike battery

    This is a bad idea. Do not repair the old pack, build a fresh one. F.eks. Bosch has made it obvious that they do not approve repairs to their E-Bike packs. I fully understand their standpoint. A poorly repaired E-Bike battery that burst into flames is bad publicity. You may be lucky that Your...

    When things go wrong... it can go really wrong!

    You do not need a huge soldering iron that heats up the entire cell. My cells are fused with a 1 A Fast blow Fuse. They do not need much soldering, just enough to fasten the thin fuse lead. My solderjoints are seldom more than a few sq mm. 1 Amp per cell?? Sure 5600/14 is still 400 Amperes at...

    When things go wrong... it can go really wrong!

    I notice that the bus bars are zip tied directly to the spacers. The plus bus is only a fraction away from the can of the cell. There is this very thin fragile wrapper only. If the bus bar gets hot and melts a bit into the plastic, the bus bar may short to the negative can of the cell, and NO...

    Megacellcharger update #4

    Just one caveat: Without full Internet access, (so the Megacell Charger can call Home in Holland), the unit will not work at all. To use this unit in a place without Internet access is not possible, not even in stand alone mode. I think they forgot to mention this fact when they presented the...

    Add 36V Battery Block to 48V Battery System

    Q: Are the cells casted in this black goo? I thought it was plastic spacers, but if the cells are indeed casted in this black hard goo, You are out of luck, sorry. ChrisD

    MY Megacellcharger has shipped yippee

    I regrettably do not own a microscope powerful enough to do the swap, so now I will just have to find the 50 to ship this trash back to Romania. Second, the built-in firmware insists on doing 3 complete cycles. Pity the Foxnovo 4S Digital Charger is no longer to buy. ChrisD

    Did anyone know this Inverter? Need help for 12V config

    Is 192 cells the total number of cells You have, or do You have 3 x 192 ? Making a pot of coffee will make Your inverter draw around 80 Amps. Using 3S 64P is not going to give Your cells a long life, but they will hold out. Collect another 64 cells and make 4S 64P. Limit the charger to 15.9...
