Dry chem does not affect powder coat, however

I bet you moved pretty fast getting hold of that fire extinguisher.
Here is a description of the battery: Bosch M LI-ION is an incredibly stable and high performance Lithium battery that can be used for motorcycles with ABS and Motorcycle Stability Control or electronic fuel injection systems, scooters, motocrossers, four-wheeled ATVs, snowmobiles and jet skis. The Bosch M LI-ION has a smart battery management system (BMS) built into the top, ensuring optimum charging / discharging and balancing of all cells in the battery - ensuring a long life and high reliability.
I think its made in germany the purchase price is 106 dollars. Amps at 10 hours: 2.4Ah (6Ah) Cold start current: 150EN Size: 150x87x93mm Voltage: 12 Volt Watt hours: 29Wh Bottom edge: B00 Polarity: 1 Pol Type: Y11 Weight: 0.90 Kg. Max mounting angle: 360 ° Charge voltage generator: Max 15 volts Charge current Standard: 1A Charge current max: 12A LED indicator: Yes

Bosch usually makes pretty good stuff and is usually $$$$. The sealed lead acid battery will do the job and is a lot cheaper, and not flammable. If you worry about weight, -take a dump before you ride, or don't drink that last beer or soda.
The easiest method to reduce the mass of the scoot + rider is drop a few pounds yourself.

Weight is not really an issue, the size is really the problem. Btw I dont think shedding those few kilos in terms of speed is gonna make any differens. The weight savings has to be more substantial to make a noticeable impact.
I just want a nice small battery able to crank a 90cc 139qmb everytime.

honestly i didnt have much luck with these batteries.. its kind of wierd tho why can we overcharge these? how hard is it to install an bms which disconects the power when overpowered etc.
ive had 3 of these batteries and all of them failed within 1 day. looking back it was my regulator which was faulty but still. why not have an bms on there like most of them. just have a override with a diode and your done.. voltage will get out of the battery when the voltage suddenly drops and when the voltage is too high a mosfet-transistor will not let power through.
hmm maybe a good idea? just add an voltage comparator and let it switch over to an diode when the voltage gets too high. and maybe a big capacitor before the diode to catch the voltage drop when it switches over If you guys want to see what i mean i can make a small schematic. If you guys want it.

The weight savings has to be more substantial to make a noticeable impact. I just want a nice small battery able to crank a 90cc 139qmb everytime. I suggest using supercapacitors they are pricey tho. They will do the job with ease. then you only need a small 12v battery to keep the capacitors full
And i didnt have much luck with 1small battery on my 90cc and my kickstart also wouldnt do the job. the gears of the kickstart just sheared of becaise of the force needed..
so i went on a small spending spree and installed 3x4Ah batteries with the stock battery. so now the batterypack should be 200A+ worthy. so when it gets cold i still have more than enough juice
If you find something good let me know then i also will give that a try since i still have a naked scoot with not much room for an battery.

Did you have a bad experience with the battery from bosch? or was it another brand?
Using the supercapacitors along with a small 12v battery sounds advertising. Do you have a link for the capacitors, so I can check them out?

I had good success with a Ballistic EV02 12cell LiFE on two different bikes (with functioning requlators) I bought a Imax B6 conditioning charger and performed a conditioning balance once/twice a year. You could use it for a maint. charge off season but I did not. The (Imax makes it) Ballistics conditioning charger is overpriced, but a conditioning charger is necessary as bikes/scooters I know of have a charging system made for Lead Acid. LiFE will charge OK but balancing cell prolongs their life. The Imax is the same (use for RC stuff) and I found it on Ebay cheap so....
After 4yrs I cooked the battery by leaving a bike key on and that was it...done. No recovery possible. I will buy another but probably the EV03 model because it has a better case shape to fit oem battery locations.
Scooter usage: Not for cheap scooters with marginal charging systems!
I run a modified stator and a TrailTech regulator on my old Jog so no problem, but the original 1/2 wave, AC lighting setup would be early death to an LiFE.
The weird characteristic: They say: in cold weather, you need to turn on ignition or light and load the battery for 30-40 sec to wake the LiFE up and then it cranks much better than if you just crank it cold. But really for our weather in BC/Wash state I dont remember having to do that much, bikes were in good tune and started easily. So your mileagemayvary.
