Support V is for Voltage
Electric vehicle related discussion, advocacy, and information.
I'm planning to do that. I have no doubt it will work so long as your battery is close enough to 48 volts.
The EVT dashboard has a fuel gauge that's making assumptions on future range based on assuming it's a 48 volt lead acid battery pack. If you want that dashboard to semi-accurately reflect the state of charge it should be close to 48 volts.
The other thing to consider is whether the controller can take more than 48 volts. I think the controller will take 60 volts and the motor has been run at up to 72 volts that I know of. There's always a risk when overvolting a controller that the components will not take the higher voltage.

Hi,
I'm a new member. Just got an EVTA Z20a. Not happy with EVTA, but that's a long story.
I have two issues.
1. I'd like to upgrade to a Lithium Iron Phosphate battery, and understand the need for replacement to approximate correct voltage. My question is: Is there a supplier of such batteries that anyone likes?
2. Tire specs: I can't find them anywhere in industry format (blah x blah x blah) only the earlier forum post about their width and diameter. Does anyone have this info?
Thx, Mac

Hi David,
I'm considering the same as my SLA charger died 2 weeks ago. I guess the best solution would be a 60V 40AH lifePO4 pack from Thundersky because they are easy to stack and can provide high peak amp.
Does this mean we have mod it like this guy has done? Not sure I have the capabilities to do that!!!I'm afraid!

Can someone help me with the price of adding a new Lifpo4 48v 50ah battery for an EVT 168 or 60v 50ah? Do I need a charger? what else? Sorry I'm a noob and although I've been trawling the internet for info nothing seems to make sense. Need info in Layman's terms.
I know of someone who is selling an EVT168 without battery so just trying to figure out the finances/possibilities.
Thanks
If you are planning to use the 60 V mod please make sure, that you connect the controller and DC/DC at 48 V, otherwise it will not work.
When it comes to Lead batteries they are often rated 50Ah at 20 h discharge (C20) where as LiFePo4 is rated at one hour discharge (C1).
Good luck
