If your separate regulator and rectifier or combination Reg/Rec is 20+ years old it is time for a new one, after that many years, it's just a matter of time before it fails. This is particularly important if you’re installing a lithium battery, as they are not tolerant of excess voltage, or undercharging. MOSFETs style reg/rec's like this one and the FH020AA from Shindengen are the current state of the art in motorcycle regulator rectifiers, they are more efficient, more stable, and more reliable than the sixty-year-old tech your charging system was designed with.

Rick’s Motorsports Electrics is the first manufacturer to offer a MOSFET style reg/rec that is optimized for Lithium Iron Phosphate batteries but is also compatible with traditional lead-acid batteries. We made a call to Ricks Motorsport Electrics and had them put together a universal kit that includes the right terminals and connectors so you can now install this new tech on any motorcycle with a permanent magnet type charging system. As a bonus of going with a Ricks MOSFET is you know it is genuine quality and not a fake from an overseas supplier. Lastly, for those of you with field excited systems check out the 10-504.

That's right these can be installed on single phase or three phase systems. Although they are designed for three-phase systems, there is no problem dropping one AC leg and running on a single phase setup. When running as single phase the output rating is reduced by 33%.

The key differentiators:

  • Lower 14.2 voltage set point that is optimized for lithium iron phosphate (LiFePO4) batteries and won’t shorten their lifespan by low level overcharging. 
  • MOSFET technology for much lower heat generation in the reg/rec
  • Waterproof automotive connectors, including housings, terminals, and cable seals
  • A connector is integrated into reg/rec making packaging cleaner and easier
  • Rated to 600 Watts or 50 amps for 3-phase and 400 Watts or 30 amps in single phase (very few charging systems can produce even 1/2 that much power)
  • No possibility of fakes like on eBay or Amazon

Kit includes:

  • Reg/Rec
  • 5 x cable seals
  • 7 x terminals
  • 1 x black connector housing
  • 1 x grey connector housing

Excellent Reg/Rec

Rick's optimized MOSFET Reg/Rec was easy to connect given Revivals excellent wiring diagram and support. I paired this reg/rec with a mo.unit Blue and new Antigravity Lithium battery. Such a sweet setup!


30 Amp mosfet voltage rectifier/regulator

This is the ticket if you are using one of the light weight/ any position lithium ion batteries on your bike! Nice connector plugs and great instructions make fore a nice installation. A bit of overkill on my basic British bike build but better err on the side of caution! I have always been pleased with my purchases from revival!

Finally a rectifier that works correctly!!! Installed on a 77 suzuki gs750, works perfect and can finally enjoy the bike without having to worry about the battery dying.

MOSFET reg rec/ antigravity 8 cell

Paired this with a Antigravity 8 cell, for my 82 magna bobber build, this Opened up all the space I needed and made my bike run a lot smoother. Customer service was far past above and beyond!!

You can tell this thing is quality the moment you hold it in your hand! It came with everything I needed to wire to my bike easily. It is a little bigger than the OEM, but it still fits in the same location. I will be using this R/R on my future projects.


Look No Further

If you are looking for a top quality lithium capable regulator/rectifier, look no further. This regulator/rectifier was easy to install on my GS450 and screams quality! I love the waterproof connectors that easily pop in and out, and was able to verify the correct voltage output via my multi-meter. Buy this, you won't regret it.

100% impressed over and over again by Jeff & Co at Revival. They’re patient and kind no matter the enquiry (currently resto-modding an R100/7 and have LOTS of questions about the Motogadget rewire) and go out of their way to offer creative solutions and out of the box thinking. I will forever return and recommend Revival.

I cannot recommend Revival Cycles enough. Not only do they have a great assortment of gear and accessories but they provide superb customer service. I was having some difficulty making it work... Jeff pointed out what I was missing and also provided schematics to make it work. Thank you guys very kindly, your crew rocks.
