I'm interested in comparing to the other Powered Up hubs, which are already documented here:

    Welcome to Bricks! I contributed answers for the three linked questions, but I don't have 88012. I'm sure I'll get it eventually, and I'm happy to open it up and document it here when I do, but it would likely be months from now. Perhaps someone else will be able to provide an answer before then. – jncraton Nov 8 '20 at 13:23
  • thanks @jncraton, appreciated. What I'm interested in is driving the motors at a slightly higher voltage using rechargeables; with either alkaline or nimh AA, the actual driver voltage will be close to 7.x volts. Using a 2s1p lipo would be an easy (moderate) increase, but I can't find a lipo that would come close to filling the volume (so energy capacity would suffer quite a bit). OTOH it would be very easy to fill the 6AA slots with 6 14500 protected LiIon cells, re-wired to 3s2p and with a JST to hook the (removed) battery unit up to a balancing RC charger. – some bits flipped Nov 8 '20 at 21:16
  • however this would be slightly above the lb1836 Vcc abs max of 10.5; so I'm looking for if it would be easier to haywire a different motor controller (unfortunately I can't find any pin-compatible IC's with a higher Vcc tolerance), OR cram in a small buck-boost to handle the 3s2p -> 9v, which would be an even 9v for the whole discharge or a ~30% increase in drive voltage. – some bits flipped Nov 8 '20 at 21:19
