Hi guys. I have been loitering an planning for a while now and hopefully the board should arrive today for my build (the Pork Chop Express) anyway. I have been inspired by @whitepony to leave a BMS out of my build (partly for cost but also because I’m looking for a simple rugged build to use for commuting so the less things that could go wrong the better!
Please could someone take a look at my layout below and just advise that I haven’t made any huge mistakes? I am planning on using 40 Samsung 25R batterys in to this 10s4p layout. I will still use balance cables/plug so that the cells can be periodically checked when I take the shell off.
I wanted to make a pack that is a little more compact than laying them flat. I have thought about doubling up the cells as below. Would this also work? (dashed line on the top diagram is where the “fold” would be.
Finally I have some questions about the gauge of the balance and main power cables? What should I use for each? Plan is to stay with single drive. I am planning on doubling up the Nickel (0.25mm) on the series connector. Would this be sufficient or would wire reinforcement be better?
Thanks for any advice you can give!
