XB-600 , 60V question for advanced users...

I should be receiving my new XB-600 in a week or so. I am wanting to add another battery for added performance and/or range. I wanted to ask if anyone sees any forseeable problems with this idea....

Add a 5th battery 12V 20ah, and perform the "shunt" to the controller.
However, in an attempt to make it possible to stay "LEGAL" and to use the original charger i am thinking of trying this....

When you hook up the 5th battery, use a reversing switch between the wires of the 4th and 5th batteries.
This would allow u to change from series to parellel. If you have them in parellel, could u not just use the 48V charger u get with the bike, then move the switch to the 60V "series" position for the performance boost?

Another reason this switch would be handy, is that for legal issues, I need to maintain the E-Bike classification to drive w/o a license. If you were actually stopped u could switch it back to 48V mode, thus bringing the top speed back down to @20mph. I mean, unless u are totally ignoring your surroundings, they wont be able to "clock" you on the ebike. thus they would need to physically ride to prove it went over 20mph.

I think this idea would make it easy to add the 60v mod and still use the existing charger and having it on the 48v mode with the 2 in parellel would essentially make them a 12V 40ah battery, greatly increasing your range.

I am new to Ebikes but i am fairly competent with electronics and electrical components. I cannot see why this would not work.

Any comments, questions or suggestions would be great.

Looking forward to helping and being helped with my new black xb-600 !!!!!

Also... living in Florida, I was wondering if anyone had experimented with adding some Solar panels on the bike. even a little trickle charge or something could probably increase the range without recharging. I could potentially need to get a 30 mile round trip out of this thing, would be nice if i didn't HAVE to charge it to get that.

if you discharge with all 5 batteries in series (at all) and then recharge with two of the batteries in parrallel, both those batteries will get undercharged. dont do it.
you will need to either buy a 12v charger for the extra battery, or buy a 60v charger.

ok, wasnt sure about that part. but if i got a 60V charger, and charged them in series all would be fine, no??? then i could still use the switch for longer range and to keep it "legally" an e-bike??

Actually, even your last supposition won't work, that is charging in series, and running in parrallel part of the time.

The problem is, that the batteries will get discharged unevenly, and therefore will not charge evenly unless you devise some way to balance the charge across all cells. The safest way, although it might not be legal in your state, would be to use a 60 volt charger, and always leave all the batteries in series.
