Something's seriously amiss when it takes longer to get the right bike than the right wife.

deecanio said:Hi All,
i need some help please guys in the battery department.
As your aware if you followed my thread i have an issue with my point 1's not being able to supply 72v to the puma through the xlyte controller reliably.
i have made myself a new controller cover/seat and that is getting made this coming weekend hopefully (will post pic of mock up later) and im now really chomping at the bit to get the bike at least to a reasonable speed but have changed my expectations slightly to accomadate the kit i already have.
with the seat taken care of i now have to face the problem which stalled my build, there are some things happening in the background with puma and factory controller testing but i am preparing to draw a line under that and i need some advice on some new cells.
If the testing is unsucessful/unsatisfactory i am now resigned to selling my beloved point 1's and buying some new batteries but i'm unsure which direction to jump in.
Knoxie advises me that 72v35a is just too much for reliability with the version of puma i have, so i think my best option is to change my batteries to give me 48v35a so i need some input as to which cells are my best bet.
Also i need to know whether there is anything that can be done to reduce the power i have with my point 1's - by this i mean before i sell them is it possible to reduce the output from 72v to say 50 ? if this can be done can it be wired so that it is impossible for me to get a back voltage of more than 50v to protect my bms? i ask this as i really like my batts and if theres anything that can be done so i can keep them i would like to do so.
Dont forget they are sealed packs so i cant get to the bms to uprate it and as knoxie found this is no garantee of sucess anyhow.
please let me know what you guys think as i need to get this sorted out and finished as the bike has been in my spare room for 6 months now and i don't feel 36v does it justice, nimh not excluded so all opinions welcome!!!
cheers

if you can post your thoughts there that would be great - i dont really understand the implications of running 6 in series - how does that effect the amps and ah?
cheers

dom said:Hi Bigh
So these do run OK in series at a lower amp? (sorry -haven't read all the thread yet)
Your suggestion of 72V20A would be perfect to get De up and humping if the batts can work at that current
Cheers
Dom
