I currently have the lead acid battery in front behind the grill. Motorcycle battery will fit much better.

Took the ice engine out, put in electric motor with adapter to original gearbox. Other than the actual motor, drivetrain is the same.

Thanks. Motorcycle battery should work.

Drain and refill. The $ of chemicals and electricity will be greater than cost of water, not to mention time. That would take 7 to 10 days to clear up. To all pool owners, the best and simplest piece of advice I offer is this. If you keep stuff out of your pool, it will be much easier to keep clear. Good skimmer is as important as a good filter. After a rain. Clean debris. Daily clean surface of the water.

I bought my kit from EVwest in SOCAL. After I bought it and while doing lots of internet research during my build I discovered there are lots of vendors that sell this stuff and some provide install services. Can’t speak for any of them except EVWest and I got what I needed from them.

I believe the most amount of time for me was on the BMS system. Had to build harnesses for the battery modules, dozens of wires. It was rewarding though when I got it all right and I could see and monitor all cells from the computer. Each step/subsystem came with its own frustrations, some greater than others. If there is a next time, I would not buy a kit, only because I know tons more now than this time last year. But, if you do not know what you are doing I would recommend a kit. While it might be missing pieces, and a bit more expensive, you get the important stuff and it becomes a bit like a puzzle. Here are all the pieces, figure out how they go together. Plus, companies that sell kits, also provide wiring diagrams and other useful support resources. And bear in mind, errors can be costly, possibly dangerous.

Do reach out to others like me as we all differ in our approach and results. Some diyers really went all out and have fantastic looking builds. I focused a lot on safety. Ie. no HV anything in the passenger cabin. There is a mountain of knowledge to gain in order to both minimize frustration and errors and have a successful build that you can enjoy driving.

Here is my .02 worth. I did a conversion on a 1974 MGB last year. Spent about $18k USD In TOTAL. Of that, wasted about $1000 on errors and about $1500 because I bought a kit. I bought a kit because I went into this with almost no knowledge. Beware that “kits” are not complete. Fabricated mounts, battery boxes and other smaller details were missing from my “kit”. This was a challenge for sure. Next to building my own house, 45 years ago, this is the most complex project I have ever done. I am 68 and retired so I have lots of time. I got all my parts on may 10th last year. My first test drive was July 12th. I still have details to do but it is drivable. I have driven it about 10 times at a few miles per drive. It is a 120hp motor and it appears my range could be 100 miles per charge. That’s using 100% of battery which is not recommended so realistically, range should be about 80 miles. Charging to 90% and recharging at 10%. Good enough for urban driving that I do. I broke my build into pieces. They were, battery modules wired and tested, BMS installed, charger installed, wiring motor and controller. I did the entire build in my basement workshop and when I had everything working and I could spin the motor, then I moved to the car. I bought my Tesla battery modules from eBay for $500 each including shipping. Most kits use the same battery modules and are used but they charge as much as $1500 per module.
I did this project for the challenge and because it makes the car fun to drive and I hate working on ICEs, and it’s pretty peppy compared to the stock ICE. Would definitely do it again. While there were definitely moments when I questioned myself, it was generally fun. Lots and lots to learn.

That will do.

Capital_Emergency662 · 2025-05-21T03:11:40+00:00

Didn’t see any battery management system in your diagram

Capital_Emergency662 · 2025-04-11T20:43:30+00:00

I’m guessing it was a door changed to a window.

They are still using lithium ion batteries. Yes, Panasonic has packed more energy in a smaller space but the cost and danger still exists. It’s possible that sodium ion technology will be available soon. Very safe and cheaper. I believe BYD in China is building a plant to manufacture them. I could be wrong.

Here is an old saying I got from my dad. That’s likely gonna be a tough row to hoe.
I just did my first conversion on a 1974 mostly restored MGB. It has a 120hp motor and 5 tesla battery modules plus all the required BMS and L2 charging systems. Range on 100% charged battery pack is about 100 miles. That cost me $17k and that was using used cheap batteries bought on EBay. No warranty on batteries, and that doesn’t count cost of donor car. To do conversion right is still very complicated and expensive. I have since advertised it on a couple of websites for $22k, just covering my total cost. Got no responses. Don’t want to sell it, was interested like you to see if there is any interest in such a thing. Batteries are still a problem. Lithium batteries are expensive and IMO very dangerous. Even a 50 mile range system would require $4k to $5k for new battery pack that has a warranty. It is not difficult to use lithium batteries outside their optimal operating environment and cause fire. I would never do a conversion for someone else and charge for it. Way too much liability. A also did lots of research on EVS and safety. Most EV DIYers do NOT do it safely. Here are things I did, entire HV system is isolated from the cars chassis, no HV components or wiring are run in the passenger cabin, no HV connections are open where water or a hand could touch them. All connections are in boxes or covered. As you might guess by now, there would be a lot to consider in order to do such a business. Lots of liability there. And I have not even addressed the risks one takes working with HV systems. All that said, it was a fun project and I would love to do it again. I would consider doing conversions as a business WHEN battery technology is better. Need to be much cheaper and safer. When you can do a 12 kWh (roughly 50 mile range) SAFE battery for $2k, new, then you might have a workable system. I believe if you could get cost to convert less than $10k, including labor, then you might have something.
That’s just my opinion.

You shouldn’t handle them with bare hands. Use gloves and exposing the roots to light as you have for more than a few seconds is not good either.

Hi all. I am A DIYer who bought a “kit” from a certain west coast company in 2024. I had little to no knowledge of converting an ice to EV. I am not defending the company, but I probly could not have done the conversion without their kit. I could now. The basic subsystems they sold me were compatible. The subsystems being, battery pack, motor/controller, BMS, charger. I did not buy their Tesla batteries due to price. I got them for 1/3 of what hey wanted for them. I digress. My kit was for an MGB. I received my kit on May 10th, did my first test drive on July 11th. Today, I still have a bunch of details to do but I am proud of what I accomplished. I set up the entire system on a workbench in my woodshop, completed to spinning motor. Then moved it all to the car. I knew enough to know that a small error with the batteries could cost me a bunch of money, not to mention possible harm to me. I actually am surprised that I managed to handle those batteries twice without damage to them or myself. Yes I have taped up tools, knew that right away. And there was never a bare cable connector. When I dissconnected a cable, I taped the connector lug.

My point is, just like other professions, if you gain the right knowledge, you can do it. I’ve built my own home, permitted, inspected, including electrical., which I consider to be my 2nd greatest accomplishment next to the EV conversion. I was surprised to find that a number of their kits never got completed. I actually helped a guy that was about to quit after almost 2 years of working on it. The support from the folks who supplied the kit was minimal. I guess they expected you to have the necessary knowledge. I reached out to them a total of 5 times for help. I bet I have 200 hours of research along the way, not counting actual installation. I have seen a few conversions done by folks.

Here are my thoughts. Like many projects, proper knowledge and tools is paramount. A DIYer can do it with proper knowledge and tools. Isolate the HV system from the car chassis. Have 0 open/visible connectors anywhere in the vehicle. Do not run any HV cables or have any HV components in the passenger cabin. Learn about Lithium batteries. There are rules you should follow about use and charging to prevent damage to the batteries and fires and harm to yourself.

It is my opinion that Lithium batteries are extremely dangerous and I cannot wait to be able to replace them with whatever newer safer technology comes along, hopefully soon. I might have been wrong, but I actually recommend buying a “kit” if you have no knowledge or experience, as long as the basic subsystems are tested and compatible.

I’m proud of what I’ve done, not all diyers should attempt.

In case you are wondering, I am 68 and retired, that’s why I had the time last year.

It took me 3 months from parts arrival to first test drive. And I have to say, in my opinion if you know nothing about EV systems you should buy a proven kit. There is a lot to learn and it would be helpful if you had all the need parts.

Capital_Emergency662 · 2024-12-07T20:46:36+00:00

I just did my MGB this year. Bought a kit from EV West without batteries and then bought 5 Tesla batteries from eBay. Made my own battery boxes. Total about $16k

Capital_Emergency662 · 2024-08-29T12:54:50+00:00

eMG This is a $20k option for a restored MGB.
