2000 EVG Global 36V bike(s)
Hello all.....I just bought two '00 EVG 36V (SX/LE) Global bikes. One in fact has a 24V battery box with two 12V-12ah batteries installed when I bought it. The lights & horn work great though the rear hub will only power on for about 10 seconds & then shuts down.
My question is, is the controller shutting down because it thinks the battery pack is low? Or is the difference in power from a 24V to 36V making the difference?
I was planning on doing a work-around by buying another 12V-12ah battery & wire it in series with the two in the box/charger to make 36v's, & put this extra battery in a bag on the rear rack.
A dealer is in fact selling this solution with the same batteries ($190), but I'm also being told by a claim expert that the controller on the 36v will not take the 12ah batteries & will "blow" on any batteries in series above 7/8ah (original). I think he's wrong.
My intent is to of course increase the range of the bikes, so does anyone have experience with this situation? Yes, my plan is to go with another battery chemistry, like NiMH or Lithium, to reduce the weight & increase the range. I want to compare the different batteries. Do I need to replace the controller with a 36V brushed 20A one?
Will this 12v-12ah battery box on another 24V EVG bike I just bought, without the box, also blow the controller due to the higher ah's?
Comments or suggestion from experienced ebikers only please.

Where did you get them? What's the specs on the bikes? Do you have pics? Need a little more info, please.
FYI. The 24v batteries won't power a 36v controller because it has a low voltage cutoff for 36v, you do the math.

The bikes were bought from Private parties that never figured out where or who could replace the SLA batteries. So the bikes are like brand new & 100% stock & have been sitting. You think I paid to much for the Red 2000 LE for $100 & the Black 2000 SX for $200? :-))
It's now my understanding that the lithium 36V/11ah battery packs from Ultra Motors Europa bikes are a direct swap & work great. So, I'm working of finding a source to buy these, besides the full pop $699 from Bike shops.
Does anyone know the amp hour limit on the EGV's 36V controllers?

It's amazing what you can learn in only a few years time! :-)
I'm now up to 17 EVG ebikes (8@36v, 6@24v, 3 mini's-1@24v & 2@36v).
The battery issue on the EVG 36v ebikes is easy. From Hobby King, purchase one Nano Tech 18.5v/8ah lithium & one 22.2v/8ah, hook the + of one to the - of the other & your set (46v/8ah charged together). Wire one + wire lead, and one - wire lead from the controller & solder 5.5mm bullet connects to match the battery. I suggest the iMax B6AC as a charger. The battery fits nicely in the side compartment.
Upgrade the rear free wheel to a 11t/28-30t & the front chainring to a max 46t (with a bit of trimming of the case to fit). This will assist the top end pedaling for speed.
The speed with increase to around 21.5mph (195lb).
You can use the 24v/400watt rear hub using the stock 36v controller & a 46v/8ah battery pack. You will not have torque, but will have top end.
A couple of the 24v ebikes, I've upgraded to the later UM Europa 36v controller/throttle. Works great, but you lose the use of the stock lights/horn. Speed is around 22mph (195lb) & a slight downhill around 25-27mph!
Any questions?
