So as some of you know I bought the EarthX lithium iron phosphate (LiFeP04 ) battery recently and there was some interest in my evaluation of it once I had time to ride with it in for a bit, mainly in hot start situations.

Well I took Marilyn out to stretch her legs over the past few days as the weather here in Northeast Florida was absolutely beautiful, 86° and no rain (eat your heart out Scott (my polish Brother)).

Although it was not extremely hot the way it gets in the middle of summer here I am still glad to report that after stopping for gas 2-3 times on both days the bike never once hesitated to start, you can just breathe on the starter switch and she roars to life.

I will keep you all posted how she does this summer in the 100°+ temps but I don't forsee this being an issue.

For those of you who may have missed my posts in the other thread about "what replacement battery did you buy" here is the link and info:

ETX36C - EarthX Motorsports

This is the biggest (cranking amp) baddest battery that I could find as a direct replacement battery for our bikes.
It is physically the same size as our stock battery but puts out almost 3x the cranking amps and also has 36AH rating vs our stock 11.4AH battery.They also sell a direct replacement size comparable to our stock CCA and a mid grade that has a bit more CCA than the one previously mentioned and they are a lil bit cheaper but I figured if your gonna go you may as well go all out and get the big one and not worry about hot starts ever again.

It also has its own built in BMS (battery management system) so there is no special charger needed as with other LiFePO4 batteries. You can maintain it off of any lead acid battery maintainer as long as it doesn't have a desulfation mode. But in reality if you are riding on a somewhat regular basis there is no need for a maintainer because with the built in BMS it self regulates the charge from the bikes alternator and balances all the cells within the battery. And if you are storing the bike for the winter just disconnect the battery from the bike as these batteries don't have the high self discharge rate like lead acid batteries do. The company claims a 10% voltage loss over a 1 year period when there is no parasitic drain (such as our clock on our bikes) so on a fully charged battery (13.4v) you would only lose 1.34 volts in a year so you would still have 12 volts when you go to start the bike a year later.


It is also ALOT lighter, weighing in at only 3.5lbs compared to our lead acid AGM type batteries which are in the 10-12lb range.

It comes with a full 2 year warranty for manufacturers defects. If your battery craps out within 2 years they will send you a brand new 1 for free. Its not a prorated warranty like most manufacturers offer. And they claim that this battery should last approximately 8 years since the BMS keeps the cells balanced for good battery health.

The BMS also has overcharge protection so if your rectifier/regulator goes bad and lets the alternator overcharge the battery will shut off the power coming in.

It also has low voltage protection so if you forget your key on and your headlight runs your battery down it will shut the power off (at a certain voltage) coming out of the battery to keep the battery from entering a fatally low charge (if you kill a LiFePO4 battery just once it is junk and not recoverable) its kinda like flipping a circuit breaker.

I know this is kind of a long post but here is the best part in my opinion.

Its made in the U. S. A.

Is it a little on the pricey side? Yes

Does it make me feel better knowing that some poor working class guy like me was able to make a paycheck by building this battery here in the good ole USA? Abso-freakin-lutely

Is it worth the money? I would say yes because it is very annoying when you stop for gas and everyone wants to come over and talk to you about your beautiful gorgeous sexy bike and ask 1.7 million questions about it and then when you go to start it and CLUNK it won't start so you have to put it in gear and roll it backwards to get the engine off the compression stroke so the starter has enough gumption to turn the engine over. With this battery (so far) that is no longer an issue.

And lets be honest, we spend $8-k$14k for these bikes, are we really gonna miss a meal over a $350 battery? Why skimp on something that important?

Thanks so much for taking the time to write up that great review

Looking forward to next one in 5 years :)


Almost 10 lbs. lighter, W:eek:W

Thankyou for the review. I looked on their website, and I kinda like the ETX18C. Over $100 less than your battery, with specs better than the stock battery. I think the 18C would do perfectly. Once the weather gets to 100F, give us another write-up.

One can never have too much capacity :D
Thats what I was thinking.... and for someone like you with the heated gear and what not the extra 24.6AH would be handy.... not sure that it would be necessary but it wouldn't hurt.

Or someone who has a lot of led under lighting that likes to leave them on while parked. The extra AH would be great.

Not sure how good this battery is in the extreme cold weather but most of you guys up north don't ride in the winter anyway so I doubt it would be a problem and the excess CCA, above what Honda calls for on this bike, would probably overcome any cold start problems associated with the LiFePO4 batteries anyway.

I'm sorry if this is a hijack, but I'm sold on lithium batteries in general. I got one off amazon for $99 shipped. It was smaller in size than the stock battery, but came with spacers, and was rated higher in cca. It fired right up this week. That's 2 winters it's made it thru. It's never been out of the bike, never been on a charger, and never any hot start problems.

Well to update this thread... I have not had a single hot start problem since installing this battery.

I did not but a charger with it since it has all the fancy electronics built in it can be charged off of any charger.

I had a problem with my micro displays backlight staying on and it killed the battery, by killed I mean it dropped down to 9V or whatever the built in cut off voltage is and the battery disconnected itself internally to keep it from dropping to low to recover from, I hooked jumper cables up from the wife's bike to mine and the minute it sees the spike in voltage it resets the circuit breaker inside and she fired right up.

Aside from that one time, which was not the batteries fault, it has worked flawlessly and it is great stopping for fuel and having people gawking over your bike and NOT having to worry about whether she will start or not when hot.

How long did that take :confuzed:
That is an excellent question my friend. As you know I am on the road away from home a lot, so the best I can tell you is it took somewhere between 5 seconds (when I closed the shed door) and 4-6 weeks (when I returned home).... Lol

My guess is it took a while since it is a small display.

You kids.... Lol

I am an old soul.... When I was born I was 40... Lol

Glad you ordered your battery... Keep us posted on what you think about it... I am sure you will not be disappointed.

my trusty kickstart
This is a Fury mod that I have never seen. Can you please post a write up with pictures? Thanks ever so much...

This will have to be next on my list. My current battery won't hold a charge for more than a week and needs replacing. $350 for 8 years of hassle free performance is a deal.

I thought you were going for the kick start mod,

Then I finished reading your post...

Rope is leading the way!!

While you fellers are playin' tiddly winks with ur new fangled batteries, my trusty kickstart and I will be motoring down the highway.

If you ain't the lead dog the view is always the same.:co-ol:

Kickstands Up Ya'll! Rope is ready to ride! Hurry up and start pushing your starter buttons!!!
All us with Lithium batteries can wait a few minutes...cause Rope is the lead dog with his "TRUSTY KICKSTART"....LOL!
Got my Earth X installed today! I kid you not, as soon as I touched the button the motor never made a round and it instantly fired up(blew my mind) You guys that ordered one will not be disappointed!
The Etx36c...680pca...405cca..a beast indeed. The Advance Auto battery I took out 120cca.....
I didn't need the foam spacers(included) as it was a tight fit.
Thank You Kbuskill for pointing the way and testing the water!!

Kinda hard to make the case for a $350 battery..... Until you have actually seen the results for yourself.... Then it's a no brainer.... Lol

Glad you are well pleased and I didn't lead you astray... Let us know what you think of it after a few HOT starts.
