I'm also building a Q76R and wondering your thoughts on batteries. You seem to use the plastic cell spacers on your builds. Would you recommend this method over laying them like a honeycomb and gluing them? Is removing a bad cell almost a guarantee in a pack? I hate to go thru all the troubling of gluing and packing them in there only to find I regret not being able to easily extract a bad cell.
I'm using Samsung 25R cells as you are, I bought 250 just to be sure.
I hate to reinvent the wheel as you've shown your packs work and I'm dealing with exactly the same frame.
I was inclined to building them with glue and get the extra capacity 20S12P but now I'm thinking maybe I give up capacity for convenience in repair.
Hey! Nice to hear about your build!
I would say use plastic cell spacer, probibly you never going need battery change, if you made it good and everything. But a good thing is that the cells get much better cooling with space between them. The cells get up in temerature while driving hard and charging. I would say use plasticspacers. But if you want high capacity you maby want to glue them.
First I had 9p then I went to 7p. This because I want good flow between the cell packs and short cabels.
The other thing is the weight. 7p is okey but it would be nice to have an even smaler battpack.
Drove alex bicycle for a couple days ago. His bike is around 30 kg. The bike was so freaking fun to drive cause the low weight. and when he runs on 7,5 kw its as mine on 10 kw.
Dont build to big and heavy at the beginning. Many do this and then they realise that the bike feels like a scooter moped.
The third thing is you always want it to be easy to lift in and out the bat package from the frame.
What controller are you going to ride on?
