Yes, I have multiple ways to top up batteries too. Recently I was in a situation where none was available. Unit wouldn't start. Had no tools. Not even a wrench or a multimeter. I knew the battery was new and fully charged so I figured it was something mechanical and called for a tow. Tow...
I'm not much for numbers. I don't know the cranking amps. Sounds like using the lithium to actually crank might be a bms problem but trickling the sla might be okay. Is that what I'm hearing?
I have 200A of 12V lifepo4 for storage. If I were to find my chassis too flat to start the engine could I jump from the coach batteries? Not a hard vehicle to start. Couple of seconds would do it if the rpm were there.
I've been down a dozen times. One time over the bars down a flight of stairs on a mountain bike. My feeling is that what you can't risk losing is not worth having. Just me setting a bad example. Not giving advice.
It's interesting to think things through. Not so interesting to let Google do it for you. I sometimes get diametrically opposite answers. Anyway, one does ones best and then lets go. If you want your boomerang to come back first you have to throw it.
I'm going to do a little table top research. Someone mentioned that electric wire insulation burns. I found that counter intuitive so I tried and indeed it does. So long as there is a flame it burns. Remove the flame and it goes out. Same with the insulators on terminal crimps. 2 types of...
There's something called 'thermal plastic beads' I've had in my toy box for years. They are non-conductive so I'm thinking just to glom a dollop of it on any part of the system that isn't otherwise insulated. I suppose there could be a heat issue if there's a bad connection or an under size...
I am paying attention to your adventures and advice. I've been waiting for all the bits and pieces to come arrive before starting to cut and crimp. I hope to insulate every bit of the system, + & -, so that I can pretty much empty my tool box onto it if the mood strikes me.
Maybe do it again with cameras rolling. How long do figure it would take to melt a terminal off? I'm sorry, what kind of battery and how big and what voltage were we talking about? I've lost the start of this thread.
