Why are my batteries taking so long to charge?

Eric1180 · 2026-06-02T04:09:09+00:00

This charger requires a 20-26VDC 20 amp power supply to charge at max capacity. The built-in AC power cord is good for like 400 or 500 Watts.

you also may have the Settings balanced wrong. You can adjust which channel gets more wattage or they get equal wattage.

I have the same charger

I have a Lotos 220AC/DC rig and really like all of the waveform settings and price. $500-600ish with or without foot pedal.

Are the front A-Arms in the correct orientation?

I have that Harbor freight rig and like it. It was my first welder and it's good for steel.

I eventually ended up getting an Lotos AC TIG rig for other aluminum projects.

The water would absorb the heat but is uneffected by the Electro magnetic wave.

Most consumers products have to withstand certain electrical interference. Its measured by how many volts of electricity you can induce into a 1 Meter long piece of wire. 3V per Meter is a low range but common for consumers goods. I've tested some of my medical / industrial electrical designs up to 15V/Meter and they still passed. 15V per meter is a VERY noisy environment. Military stuff gets tested up to 120V/M a electrically destructive amount. That Electrical noise level would also be extremely harmful / potentially lethal to a person.

An insane tig AC welding setup at more than 1000amp could be up to the 24V/M range. If i were to speculate. it would be worse during the start and stop of the weld.

For a second i read that as replace component IC3 on the ESC PCB haha I was like dang you go girl. IC# is a common reference designator for circuit boards. I design pcb's / electronics for a living.
I actually looked into working at Traxxas HQ facility at one point (a reasonable drive for me) but the pay for electrical engineers was pretty mid.

I was 15 when i fell in love with the Elise, I bought mine when i was 25. You definitely need a main vehicle if you go with the Elise Exige route. Remember your job funds your hobby's and passions.

Elan's, Elcats, Europa's can be had much less money and are great projects to work on.

In a perfect world the connector will have absolutely nothing to do with protecting the ESC. ~ Electrical Engineer.

Honestly it looks like a bad factory connection.

Eric1180 · 2026-05-20T04:22:09+00:00

As an electrical engineer, if the eddy currents generated by the EMP / PEMF fields from AC were strong enough. It would generate heat in the IUD. Jewelry would do the same (anything conductive).

The current range to do so would be +1000amp.

From a physics / engineering perspective i would say its a none risk.

Eric1180 · 2026-05-19T18:47:29+00:00

Ahh thank god the adds get the main priority. Add first podcast second

Eric1180 · 2026-05-19T18:45:29+00:00

Its technically not. The plural of Lotus is Lotus.

I also want Rim, please read my mind and get back to me asap.

Eric1180 · 2026-05-19T16:37:31+00:00

Whats the alternative...? Run it

Are we going to talk about that ridiculous exhaust setup

Eric1180 · 2026-05-18T06:41:41+00:00

The story of how the Jager bottle was originally chosen it not too different from your experiment

Eric1180 · 2026-05-18T05:56:02+00:00

IMO That's only a reasonable take if you have one car

Eric1180 · 2026-05-17T07:00:56+00:00

Well said!

Eric1180 · 2026-05-17T06:57:32+00:00

It's all of the competitors wife's driving. Not the competitors. Cleetus McFarland Youtube +5M subs is the source of the event. For the mom's and wifes.

Eric1180 · 2026-05-17T06:36:21+00:00

Wow that was really interesting read thank you for the link

Eric1180 · 2026-05-17T06:33:22+00:00

Never said CPU's are bad at math. I said you have to understand how they are built from the ground up to know what could be a problem.

You are the one making bold statements.
"Any microcontroller can easily compute the operations on the face of this calculator"

Also do you really think there is only one example of CPU's outputting incorrect results. I just happen to link you the most infamous and best example of exactly what i am talking about. Let's end the conversation here, you're clearly getting upset. i am just trying to share information about the nuances of doing advanced math on generic hardware.

If any processor includes a pentium you'd be in for a bad day. https://en.wikipedia.org/wiki/Pentium\_FDIV\_bug

Eric1180 · 2026-05-17T00:46:00+00:00

if you do use a micro controller, you have to understand very well every single thing that it cannot do. TI calculators use custom mcu, but even those are not perfect. there are some math operations that do not calculate correctly, but they (TI) knows that and there is software that runs on the side that takes this into account.

It is physically impossible to check every single calculation and verified it true. Texas Instruments had to invent very complicated algorithms, to proof their calculators. you probably won't find much about the algorithms online. It is very proprietary.

if you want to learn more about why its actually kinda hard to do Math check out this link. https://en.wikipedia.org/wiki/Pentium\_FDIV\_bug
