First :You can charge a bettery with anything that puts out the right voltage and current.Second :If you are not integrated with the BMS and running an appropriate algorithem for the specific battery design
you will damage the battery Each type/make/model/chemestry of battery, and battery construction is different. There is a reason the digiNows are the only non OEM charger which does not void the warranty, this integration is imperitive, and Zero will know that you used a
non bms integrated charger and
the battery warranty will be voided.
Third :Technically speaking if your bike is very old and has a non can integrated calex onboard you could replace it with a "dumb" 1kw charger without warranty issues. HOWEVER, if you have a bike or battery newer than 2014, your calex (onboard) charger has canbus, and listens to the batteries for faults and dangers required for SLOW charging.
Fourth :Your bike is probably pretty expencive. And I have done a LOT of talks with Zero about charging and warranties and legal repurcussions... if you dont mind accidentally breaking parts that will cost you between $700 USD and $7500 USD then go for it, just be aware, it is expencive and could take months to get replacement parts as only hackers break these parts and so they are not often needed. Of course there is always the small risk of burning your bike down in the garage 6 months after you deem your setup is safe because it wasnt actually then your bike, your dog, your wife, children and mistress will all be consumed in a glorious blaze of fire because you made a simple mistake.
Fifth :Batteries are fucking dangerious. Like for real... all of us that have worked with them or charging have been seriously injured and some of us have died on higher voltage systems. The charger you described CAN kill you
if you make a mistake which, unless you are Jesus, you will. So if you plan on messing with it just always keep that in mind.
I'm not saying stop what you are doing you'll die! I am mearly providing the relevant saftey information without any filter or mask to make EVs sound safe. If they are built properly they are, but when you start hacking on them that saftey GOES OUT THE WINDOW!
I remember when Terry was first modding his bike it used to shock you all the time. Which means if your child walked upto the bike and touched it they would have gotten shocked. You wouldnt want your neighbors child to get shocked on your bike and the lawsuit that followed I bet. We all forced Terry to fix his bike, and in fact Jerimiah Johnson stepped in and helped wire it all up to saftey specs. Now Terry's bike is safer for children to be around
I also remember when I made the SCv1 (A LONG TIME AGO) part of the testing Terry was doing for us got him shocked in the nuts once or twice during the rain... and so he made me fix that before we released the V1
so we're even.
Closing :Only do this if you are OK with possibly hurting other people, children, or burning down other peoples property with your bike.
Also, only do this if you are wealthy enough to accept the losses of paying those peoples medical bills and property losses along with your own legal fees, and probably theirs as it will be your hacked bikes fault. And Zero will say as much.
Warning note :As mentioned Zero does follow these forums and take note of people doing dangerious things to their bike. I would be very surprised if there wasnt already a note on your vuin to check for this if you go in for any powertrain issues. They are very smart. Sadly a lot of people think they are stupid, and dont know all the bad shit that has been done to a bike... they do.
