Hi Folks
Terry H is doing a end to end trip on his Oxygene EV scooter between lands end and john-o-whatsits, it has a Zivan NG1 charger fitted to it, currently he has some nickle zinc batteries fitted I think to it but is thinking he may have to go over to lead acids during the trip if these batts fail.
Any how the charger is rigged for these Nickle units and their style of charging, the question is can the Zivan NG1 be adjusted to suit the PB's with just a adjustment on a couple of blue pots he's found once he removed the covers or is it more the case ( which I suspect) that it needs to be actually reprogramed to the PB's charge regime ??
You can "just" make out the pots on the PCB on the below pics, sorry they are so poor its just what Terry supplied me with.

Thanks Paul, athough I'm not sure what the pot is marked as, I have'nt seen the inside of charger personally.

hi, i've got the same scooter but 1 of the 4 nickel batteries has died. i've had no prob replacing with SLAs but having trouble getting an onboard charger that fits, if the zivan can be adjusted that would be great! (i've been told not but these weren't bvs bods) please let me know if you guys work it out!!
