Thanks guys. I am in the first stages of rewiring my 1984 k100. Found you channel and it has and will be a great help to me. Will be buying products and supporting you in the future. Thankyou from Australia
Welcome aboard!😘
Awesome thanks for answering my question. Looking forward to more videos. I need to simplify a harness for a cafe racer. Good to see yalls how to videos. Great series
Great video, keep it up!
Hey! Awsome videos guys, so much learning : ) thank you. would you advice a lithium battery on a Suzuki GN 250?
If you're looking to relocate your battery and or save some space or weight then a Lithium battery will work great. Keep in mind that you will have to upgrade your regulator/rectifier to one that is Lithium compatible.
This is a great video series and thanks very much for putting it together. Will you be offering a complete package for sale? I would be interested in buying all the components required to modernize an old Norton. Cheers from Germany.
Since there's no singular answer that works for everyone we may never have a comprehensive kit but we do have some bundles of the universal components.
The battery charging at voltage of 14.19 idle I feel that is too high even thou I installed the Rick’s RR on it. Any advice ? Thanks
You forgot that these batteries don't work very well for those of us that live up north where it's cold, especially us neighbors in Canada. These batteries are very sensitive to cold weather. Even leaving your key on, with high beams and flashers on may not work very well below 0°C. Important thing to know if you want to ride daily and year round.
To be honest we've been using and selling them for years and I've never seen or heard of that being a common issue so it didn't enter our minds to mention it. LiFEPO4 batteries can take a moment to "wake up" while they generate enough internal heat, that can happen in cooler temperatures above 0ºC as well but if you press the start button for a few seconds, release and reattempt a moment later they should respond.
If you're operating a small case battery and you leave your high beams or your key on it will of course drain the battery, since it's a smaller battery than stock you won't have nearly as much room for error.
is there a way to keep the Lithium battery from discharging below its damage point with the munit or the reg/rec or some other shut off?
Any time we're actively working on a bike or if we know it's going to be sitting for a while we put it on an Optimate TM-471 float charger. These can be used to will help avoid draining the battery while the bike is on but not running during service and help to avoid a slow drain from the milliamp draw of the m.Unit over an extended period. They can also on occasion rescue a "bad" cell in a Lithium battery that's been drawn too low.
Here's a link to them on our site. shop.revivalcycles.com/optimate-tm-471-lithium-lead-acid-battery-maintenance-charger/
open a shop this side of the pond and bring ya gadjets with ya!!!!: )
🥰
Lithium battery's don't like it in the cold. Had a lot of problems with mine below 10°C
How do you guys rate the gel batteries vs lead-acid or lithium-ion ones?
I don't know how to give a complete answer to this. We've never put them all up side by side and put them to the test but they all have advantages and disadvantages. Gel and Li don't leak acid all over your bike. While lead acid technologies are more tolerant to over over draining and to some degree overcharging. We stand behind LiFEPO4 technology because these pack more power in a smaller case allowing us to create custom solutions that you couldn't accomplish with any other currently available battery technology.
Wich battery would you recommend for my CX 500 in combination a Mosfet Regulator Rectifier? I Need a small one that will hide under my seat!
We have an entire guide in our knowledge base on this very subject! technicalarticles.revivalcycles.com/hc/en-us/articles/360016751531-How-to-Pick-the-Right-Antigravity-Battery-for-Your-Bike
@@RevivalCycles Thank you! Are you allowed to ship those batteries to Germany?
hi guys, I have a 1990 BMW K75 restored, what battery size in the antigravity batteries would you recommend me??
Thanks from Spain.
I would like to know this too for my '87 K100, the alternator and reg/rec are built-in in the K-series. Will it harm the lithium battery?
I would not go smaller than an 8-Cell but the more important question is can you use a Li chemistry battery? I can't say for certain. If the charging system is producing more than 14.5V it will best case scenario shorten the lifespan of the battery. But if it's producing much more than 14.5V it can cause a cascading failure that results in a melt down and massive voltage spike that can damage even an m.Unit.
See my reply above
Revival Cycles Thank you for the reply! The charging system of the K75/K100 produces 13.7-14.5V, so I guess it should be OK?
@@RevivalCycles OK, THANK YOU SO MUCH FOR RESPONDING TO ME, I WILL MAKE SURE THAT THE VOLTAGE IS THE ONE GENERATING THE ALTERNATOR BEFORE MAKING A CHANGE.
Hi guys I have a BMW r100/7 1977 and I was looking to buying an antigravity battery what components do I need to change
By the way I have very little experience more the info the better thanks
Hi Andre,
We nearly always recommend a reg/rec upgrade to a Lithium Optimized component. Even when they are in spec OEM reg/recs put out slightly more voltage than Lithium Batteries can tolerate. Lithium batteries have a lower voltage set point of 14.5v than OEM Reg/Recs which are typically set to 14.8v.
If a Regulator is in spec and putting out a steady max of 14.8v then often what happens is a Lithium battery experiences a shortened life span, sometimes 6-12 months. But if the Regulator is faulty due to poor quality or age and thus putting out higher voltages it can kill the battery much sooner and even lead to a catastrophic meltdown within the battery which can be devastating to the electrical system. I've not seen one catch fire but they will smolder from within, melting into a blob making a terrible mess and can cause a huge voltage spike.
We sell a modern replacement for the BMW regulator and diode board and we have concise wire diagrams for how to do this mod to a BMW charging system on our site.

Thanks for the info 👍🏼
Can a m unit be used on a pma setup with a capacitor no battery?
Unfortunately it can't be. The m.Unit needs a minimum constant 6v to power up and a capacitor will not provide the power necessary.
Ok thanks. My concern is if there would be a overcharge condition even tho I'm using a mofset setup. And a lithium battery. But I was able to find a lithium battery with built in overcharge protection. So I should be fine. Just don't want a fire under my seat..Thanks!👍
