:? Okay, I am in the process of doing some upgrades to our Rad2Go E-36 Great White scooter during the cold winter months. In addition to adding a battery level gauge and an ignition switch I started looking at the cheap little Jintong batteries that came with the scooter when I got it used off of eBay ($170 - killer deal).
I would like to get more range on the scooter by upgrading the batteries from the 3, 12V/12AH bricks that are in there to something with a little more reserve capacity. I was looking at 3 of B&B's HR15-12T2 which is a direct drop-in for my current battery with 15 AH (listed) as opposed to 12 - that would bump the available A/H from 36 to 45 - not too shabby. HOWEVER - I also see that B&B has a 6V, 12 A/H cell ( BP12-6T1) which has the unique feature of being only 2" wide - I measured the battery tray of the scooter chassis and I could fit 6 of these in the space of my existing 3, 12V units. So.....
Is there any downside to using 6, 6 volt cells in series to give me 36V and 72 A/H instead of 3, 12V 15A/H cells with a total of only 45 A/H? I'm not enough of an expert on battery technology, but it sure seems like the right way to go - the cost difference at www.electricrider.com is only $3 more for the 6V cells. Now, the weight is about double but I'm not sure that would not be worth the huge jump in available Amp-hours.
So experts, whaddya think?
Thanks in advance,
