    Mechanical force on Lithium cells

    Hi everyone, I've got a question regarding how much force one could apply to a cylindrical lithium cell (LiFePo4 in this case). My plan was to build blocks of 32700 cells and clamp them together (plus to minus to get series connections). However, this would mean that quite a lot of force would...

    The Need for Fusing Individual Lithium Cells

    Hi everyone, I'd like to discuss the need for fusing individual cells within a pack. The idea behind fusing cells is that when one cell fails (shorts), the fuse burns, the failed cell is isolated, and the rest of the pack continues to function. Tesla does this by using small wires to connect...

    Two lithium chargers in parallel

    Hi everyone, Does anyone know whether or not it's possible to charge a single lithium (LiFePo4 in my case) with two parallel chargers? The reason I'd like to do this, is that for my application (an electric boat) sometimes I'm constrained by a 6A circuit breaker, while other times I could go up...

    Charging 24S LiFePo4 battery with 20S lithium charger

    Hi everyone! I'm building a 24S LiFePo4 pack. The chargers for these packs have a cutoff at 87.6V. Could I also use a 20S regular lithium charger for my pack? It should work, right? As far as I know, they're both CCCV chargers. The only thing is that the 20S charger has an end voltage of 84V...

    Motor for 18ft Electric boat

    Hi everyone! Together with a couple of friends I am converting a small 18ft canal boat (about 750 kgs unloaded) to electric. We hope you can provide us with some help in the motor selection. The required motor power is roughly 1.5 kW constant, with peaks up to 3 kW. The propeller shaft...
