Despite reading a lot of lipo threads a few things are not clear to me.
Is it ok to mix and match lipo packs of varying c rates?
For instance, say I bought some very cheap 5s 15c 5 ah blocks. 4 of them for 72v. Later on with more money, I get some better 5s 30 c blocks. Would there be a problem with putting a 15c block and a 30 c block in a 2p connection before series connecting them for 72v? This is assuming that the pack would never be used above 15c of course.
Would it be better to make a 72v 15c pack and a 72v 30 c pack and then paralell the two?
Would it be better to make a 36v 15c pack and a 36v 30 c pack and series the two to get 72v?
Or would it be better to run one 5 ah pack of 15c cells, disconnect, and then run the other 30c pack?
Another thing I am wondering about, would there be any problem with putting 5s blocks in series with 6s blocks? So you'd end up with a 22 s pack? I don't see why not, but ignorance is bliss.
I'm thinking 2p 5s + 2p5s+ 2p6s+2p6s. Those 8 lipo blocks could then be arranged in many ways to have 36v 5ah, 48v 5ah, 40v 20 ah, and 80v 10ah. Again, they may not all be the same c rate. And no way would I try to paralell 5s and 6s.
Seems like a good way to have many ways to use the lipo, besides just 80v at the spooky tooth. 5s and 6s both have their appeal, especially the price now of the 5s 15c packs.
