Sanity Check: About to buy this Lithium battery for Hawk 250

Seems like this one will do. Thoughts?

Buy a Yuasa, even that code is a Yuasa one. I only have praise for Yuasa battery.
Late 2016 i put a Yuasa 12n9-3b on my motorcycle, it died one month ago.

Seems like the Yuasa battery is $50 bucks cheaper

You mean 50 bucks more expensive.

Same price here in the U.S. more or less a couple bucks.

Now, with that aside, if you are heart set on a Lithium battery I would first make sure that your bike will be able to maintain the proper voltage range to properly charge and maintain said lithium batteries. Generally most lithium bike batteries require a minimum 13.2 to 13.4 volts, and no greater than around 14.2 to 14.4 volts. Too low or too high on those voltages will greatly shorten the life of the battery.

I can almost promise you that your bike won't meet one of those two ranges. When I put a Battery Tender lithium battery on my last Hawk I also upgraded the regulator-rectifier to a modern self regulating MOSFET unit and capped the regulating circuit (Black wire) from the harness in order to get a steady charge voltage.

Now, with that covered I would highly suggest sticking with a Bikemaster, Battery Tender, or Antigravity battery if you are wanting to go LiFePO4 battery. I have run all three brands on different bikes with great luck. I currently have an Antigravity in my VFR. 3 years, still strong.

Suggestions on regular battery ( non lithium )?

I went with this one which only cost me $25.95 OTD on March 27th getting the Condition: Used - Very Good - Minor cosmetic imperfection on top, front or sides of item. (which usually means basically new in my experience) Item will come repackage
New it's $32.00
rechargeable YTZ7S Power Sports Battery - Replacement Motorcycle Battery, 180 CCA, High Performance, Zipp Battery

but as amazon shipping is soooo slow (even with prime) currently I haven't gotten it yet and don't know how good it is or isn't.... it does mention in a review that

"cranks my RPS Hawk 250 effortlessly. I had to add some foam blocks to fill in the space in the battery box but I shaved a pound or so of off the bike with this battery. The bike came with an archaic wet cell battery which could easily leak. These AGM batteries are the ticket."

Given cost and that lithium batteries can require some maintenance I personally would not go with a Lithium.... but for some it may be the ticket.

Thanks Kenny, no doubt my point that I do not need a lithium.

That batter has pretty good reviews and the price point is where my mind is at.

no worries .... to be frank we mostly buy chinese bikes because they are cheap and cheap to mod.... so of course i would assume we all would be kinda frugal elsewhere too... i know i am. and the stock batteries are pretty mediocre .... another spot that can make a difference is changing that supe tiny ground cable... bought one at wally world for under 4 beans.in the auto section near all the ......... batteries ... i did have to drill out the correct err close enough sized hole for the battery post...too easy. the stock one is next to it for comparison

I agree on the ground cable. I have upgraded that one twice now.

but you will like this mod.... it's pretty easy taking under 30 mins and CHEEEEAP! under $5 and it's readily available at wally world....
it's the best kind of mod.

had I done this mod before buying the battery I may have waited to buy the battery... I mean I still needed a better than stock battery because the are mediocre but the better ground made alot of difference...
Of course make sure your connections are clean (get out a brass brush or sandpaper or steel wool or whatever) and tight..... things are always better when they are clean and tight.

I put on some NCP2 (battery corrosion protector) also because it was there....

I've got Mighty Max gel batteries in all three of my bikes. No problems so far. This one fits the Hawk (you need to add some "padding" to make sure it doesn't move around).

I'm in the Lakes Region of NH and to be honest our Amazon Prime is just as quick as before all this craziness. One more reason to live away from overpopulated areas.

this might be a better and cheaper option...

my amazon shipping is like 2 weeks with prime.... its pretty slow....

Wow thanks as always for the responses. I was looking at Lithium because I bought a $25 Amazon AGM “Pirate Battery Brand” and I jacked it up by overcharging, but even before it wasn’t reliable turning over the engine. I’m going to look in to beefier cables too, I’m sure those wimpy ones aren’t helping me either. I think I’ll try the AGM battery Ken Stogie recommenced.

Recommendations for better cables? ETA: Just saw the linked thread on this!
