Preferred Regulator/rectifier combo

[Valentinik]

I'm looking for a Regulator/rectifier combo for my build to maximise space under the seat.

Is there a preferred model or supplier of unit that is better than others (DS, ricks, electrex,etc)

Also I'm not sure if it makes any difference but I am using a lithium battery.

Thanks
Mike

I got the Electrex World version for my CB350F and it came with all the correct connectors to plug straight into the OEM harness.

It did not, however, come with any instructions, hints, pictures or clues as to how to mount it. It does not fit on the original mounting brackets, but I don't think any of the other combined units do either.

So far it is working fine on my Motobatt AGM battery.

I'm using an electrex unit as well on my 550, and am also running a motobatt AGM battery.

Thanks. It's, just had a look on their website and it  state they don't work with lithium batteries so il have to look at a different brand.

I'm not sure that you'll find any that will.

Lithium batteries tend to be very finicky about the charging rate, which is why you need a specialist charger for them.

Dead right their! Lithium batteries are great for a multitude of uses, but I personally shudder at the thought of one sitting close to my arse! Fine for a total loss ignition system like race bikes, as they are plugged into precision chargers to recharge them. If they overcharge or go wrong they are a disaster waiting to happen. (Remember science at school, lithium kept in a dark jar, under oil to protect it from oxygen, and teacher placing a very small piece in water!)

I am building a CR and so have little space available for a battery - I have built a battery box to take a 'Shorai LFX14L2-BS12 Lithium Iron Motorcycle Battery' under the seat hump. The battery seems to be the recommended fitment on all the forums and as the bike will be used on the road with electric start and light, I can't use a total loss system. The battery adverts don't mention that there's an issue with charging (other than you need a special battery charger. Is it only the rec/reg combined unit the issue - ie, can I use the separate regulator and rectifiers without problem, or is it a charging issue generally. There's no mention in the spec that it has to be used with a total loss system only.
Thoughts and advice from you experienced sparks much appreciated before a through more money at this project!
Cheers

What I was trying to point out is lithium batteries if overcharged may explode, big time, have a google around about the problems with little ones in mobile phones catching fire and burning houses down. Also, in. Australia and a few other countries they are totally forbidden from aircraft, and only permitted to be transported by road or sea. Question is, do you want something that unstable close to your arse or other body parts!

UK also ban them from aircraft as well now Hairy. I was in Poland for a week earlier this month , flew with Easyjet and they made a real big thing of it as you go through to board the plane.

[hairygit]

And try fighting a Lithium fire! Water can cause it to explode violently, foam is no better, and even CO2 struggles with it! Glad to hear European airlines are aware of the dangers now, so, I ask again, who really wants a lithium battery anywhere near delicate body parts?

[philward]

And so is there a solution to the conundrum of space versus battery power in the CR replica situation?

[hairygit]

The major hurdle I can see is the need for electric start, if it was kick only or push starting it would be a whole lot easier to answer that

It seems like the lithium battery is not a great idea so il have to rethink where to mount the battery.  Can I ask what model of motobatt you fitted?

Thanks

The problem is that, since lithium batteries are a relatively new innovation the rectifier/ regulator units, either combined or separate, are not designed to meet their very specific charging requirements.

The set-up on my Moto Guzzi was so crude that it even fried an AGM battery on a continental tour.

If you want reliable performance go for an AGM type. They give you mounting options but unfortunately they are no smaller than a standard wet type lead/acid battery.

I used MBT9B4.  It's a smaller battery but I typically kickstart the bike and have converted all lights to LED.  That said, I've had no issues.
