Fitting a smaller battery after ditching the E/Start
« on: April 28, 2013, 08:48:57 AM »
I am dealing with an electrical fault on my Sixty5 in another thread, but out of interest, now that I have converted my bike to kicksart-only and will sooner or later have to replace the battery, would it be ok to get a lighter-duty (smaller) battery, say, as fitted to non-E/S Bullets? I ask this because both the alternator, and rectifier/regulator units are different part numbers on E/S and non-E/S models.

Yes, it's okay to use a smaller battery.
The KS bikes use a 5-amp hour battery.
The regulator is supposed to only give the battery what it needs, and dissipates the rest as heat. That's why the reg/rect have aluminum cases with fins on them, and they should be in a place where air can flow over them.

However, it probably wouldn't hurt to keep the larger battery if you plan to use some electrical accessories or added lighting.

The Yuasa or similar YTZ7S is compact enough to fit in your toolbox. Been using one this way for years. Opens up the bike to give a cleaner/lighter look. I did buy a BikeMaster gel battery about 1.5 yrs ago and it did not last. I would not recommend this battery. My Yuasa lasted about 5 yrs at about double the cost of most replacement batteries which tend to last one or two seasons. Sometimes it pays to spend a little extra.

Anyone ever try a Shorai yet? It's a lithium/iron battery that's small and lightweight.

Yes, a few people have tried them and reported that they like them.

I have not personally tried one yet, but I plan to try one for my next batt.

Good to know. My ES has a big DieHard. I can barely close the battery box lid.
Now back to the regular thread!
