Thanx for the help
Sorry I couldnt been of more help. I never played with SLA batteries besides charging my vehicles battery and golf cart 4x12v. I just know SLA isnt the best choice for electric motion, and going Lithium is better.
I was interested in my 80% comment as I remember reading it somewhere, but reading on its called the Peukerts effect. So you can see the difference below between the two chemistries. Remember that SLA Lead Acid is much heavier, sure its cheaper up front, but they dont last long neither, oh and they sag huge under load. Where as Lithium is lighter and lasts longer.
Putting all this together - Example:
Batteries: 12 - 12V Lead-Acid, rated at 100 ah
Pack Voltage: 144V (12 batteries x 12V each = 144V)
Pack Size: 14.4 Kwh (144V x 100 ah = 14.4 Kwh - Remember, we can not use all this)
Usable Pack: 6.336Kwh (14.4 x 0.8 x 0.55 = 6.336 Kwh usable)
If we had a lithium pack of equal voltage and ah, the range would be 44 miles (because Peukerts effect does not play a role)
14.4 x 0.8 = 11.52 kwh usable / 259 = 44
Your battery guage would be a simple volt meter, and you just have to know your Low Voltage Cutoff, and you see over time how much you have left. Governor, like I said before, no clue. You saying it will govern your speed to say a set speed limit?
One thing you have to keep in mind with the charger for SLA is how much charging current can the batteries take.
1. My battery gauge is not working.
2. How do I take the governor off
3. Is there a quicker charger I could purchace.. my bike is 72 volts and it’s taking 10+ hours to charge..
