Full throttle Electric Supercharger Build Thread

Regarding the recharge rate, it's always 8:1. However, with well conditioned batteries you have a certain amount of reserve with the first few engagements of the day, so the recharge rate is somewhat better then 8:1. After that reserve is depleted , you're back to 8:1. If there is considerable delay between engagements, you once again build up that reserve.

Regarding the voltage, there is a tolerance of +/1 0.2 VDC from controller to controller. I've had four of them and they all had a different charge point. My current controller sits at 28.5 to 28.6 VDC.

As far as damaged or worn out batteries, has anyone had to replace them yet? I was considering ordering a spare set just to keep around in case I need to replace one or more... but if it's likely to be a year or more, then I won't.

I've had the system for 1 year and haven't needed to swap out batteries. But I did swap out a single dump pack battery to see how the system would handle a single new battery. (Just fine btw)

One year with the original v1.0 battery pack and 6 months with the v1.5.

Fenton or Rob will be the bellwether for battery longevity. Fenton has been operating on the same batteries for over a year and a half and Rob has a VW that he has been operating for years on the same batteries.

I had a moment where I mistook @robwbright for @Robftss and got really confused as to why the architect was asking about ordering replacement batteries.

Is it Friday yet?

If it makes anyone feel better my meter reads 27.9

28.1 for me. Rob said optimal at 30c is 28v and 28.8v for 20 Celsius iirc.

Thanks for all the responses everyone. I guess it's no big deal because the car goes run great. I'm surprised no one has had any battery issues yet. I had a Saturn station wagon once that the battery would always die in less than a year. Because of the heat I guess. The only battery I ever paid full price for was the first one because all the subsequent ones had a prorated warranty.

And where did that battery come from?

just wondering if someone on this forum can give me some ESC mesurments please.
I need the lenght of the cables from the controller to the batteries and also the lenght of the cables from the controller to the ESC unit. havent got my ESC and want to check a few things out in engine bay.

Thanks John

Why do you need the lengths? Just curious? Everything is included in the kit including looming for hidding cables.

[myioz86]

Well i am from oz and i dont like the way gums has run his cables over the top of the motor . i want to run down the left side of the car to controller hiding the wires as i go , then from the controller under the air box to the ESC unit. as far as i can tell doing it this way all i need to extend is the pedal switch. just need to know how long wires are on american vertion. this way i dont have to wait for rob to mod on to suit oz cars.

Thanks John

[myioz86]
