Thanks. "

" Hi Flo. Nice to see things have woke from winter sleep A-OK!
Are you running with a BMS installed? The one I am using from Thunderstruck is doing great... no more manual balancing for me anymore.
The convenience and peace of mind is worth the $$$ in my humble opinion.
I just put new tires on and reduced my drive sprocket down to a 13 tooth.... I forgot how fast this beast goes now but I'm still only getting about 42-45 (about 70 km) miles per charge. I really only use it for goofing around and riding to work, which is only a few miles ( I could walk ) so one charge lasts me all week!
Hopefully I can get 5 years of use out of these batts so some new battery tech can come our way! This thing keeps getting better and better!!
Like a good bottle of Rotwein... better with age! "

" Hi all,
just hit 3000 km last weekend so i guess its worth an update.
Took off fairing this week to inspect.
As before all conversion components perform flawless, using lock nuts or locktited screws exclusively nothing has come loose, only maintenance so far being chain lubricant. Back wheel brake doesnt work too good anymore but thats nothing electric related.. will have to source a new one i guess..
Bats hold up fine, i do not see any degrading, and under power they still show only 0.1V dip per cell across the board.
Speaking of bats:
I had previously mentioned the cells "sitting" at slightly different voltages, as it seems i have been wrong.
Some of you might remember that i manually balance my pack (split into sub packs) using an rc charger.
A couple of weeks ago i bought a new balance charger, Model ISDT-8T, simply as it would balance up to 2 amps per cell/ channel and does active balancing while charging. As it is possible to calibrate the charger i went to my buddy Robert and we calibrated it using his high quality equipment.

Surprise, surprise, my cell monitors in the sachs cockpit still show 0,06 Volts difference after balancing. So actually the pack is just fine, only my monitoring is worth crap.
Need to find out if these can be calibrated as well...

Anyway getting the cells into balance is now greatly more convenient, i can get all 4 sub-packs done within 20 or so hrs. easy. As this is needed only every two weeks or so thats fine with me.

Oh - actually rode it in the rain this week too for the first time, without getting electrocuted- so i guess i must have gotten it right.

Stay save and healthy

greets

" Fantastic work! I like the fact you kept the bike looking as original as possible. I'm in the process of planning the same type of conversion on a Honda CT90 Trail. "

" My 13 inch 72V 8000 watt QS motor should arrive in a few weeks. So far it is has been fun to tool around town but not fast enough or enough range at this point. So far I have upgraded to Honda Grom Forks and when I get free time, I will install the aftermarket shock and brakes/levers.
I have a 3000 watt Greentime controller rated for 80 amps at 72Volts. Rumor has it, this controller can be shunt modified to pass more current. Once the motor and controller are installed, I will be building a battery pack to handle the draw. "

" Since things are slow on the forum lately, I will post news about increased EV registration fees that have just become effective in California this month. I have no idea if the the additional $100 per vehicle will apply to home-built electric motorcycle conversions. I guess you will have to await your next vehicle registration bill to see if that happens. Article attached. "

" Thanks, I have not posted because I am waiting for parts to arrive. The virus slows everything down I guess.
The factory in China (QS Motor) says it's going to take at least another 10 days before they can ship it out, and I am still waiting on my BMS to arrive.

I will post a lot more pictures once more things arrive.

I have found some interesting information about my motor controller though that is going to require me to re-pin the connectors;
The thermal sensor wire is routed to a different connector than the one that the motor uses. "
