A lovely thought Nikki but sadly one thats not that practical due first off the 27 batteries in the pack, and the fact dropping the packs down isnt a 5 min job
I know what you mean though and I suppose in hindsite then when I swapped the packs around it might have been prudent to attach loads of sensor wires out of the packs to do such a thing.
But then also I quite like to keep the clean lines of the vehicle inside and out, you start adding loads of this and that to it and people then look at it as a geeks vehicle and I dont think it helps the whole EV image .
I personally dont think theres any charging issues and I think its more the fact the energy meter can only read what data its given by the puter and then attempts to calculate a percentage of energy left. If its given duff info then it calculates duff info
The saft nicads do seem to be very robust units and can cope with very low discharge levels and even dont mind going reverse polarity from time to time ( not great but they can cope with it )
They are certainly far tougher than lead acids from my experiences so far
