I need to replace my battery and want to use a lithium battery. Anyone know of what brand and model will fit?
Sorry if there is an existing thread on this but ifvthere is, I couldn't find.
If there is a reason not to go to lithium, please let me know and I'll stay with the norm.

 

I’ve been using a Battery Tender (brand) BTL12A270CW Lithium battery, fits well in stock box, weighs 2.2lbs and has built-in BMS.

 

You can definitely go with Lithium battery, but I would highly recommend to upgrade the R&R (regulator/rectifier) before you do it, Lithium batteries have a tendency to like a bit higher voltage charging than the OEM R&R, not to mention, it is a general recommendation on VTR's anyway, the OEM are pretty crappy to begin with and can potentially cause a very expensive repairs when they fail with 50% chance of frying all your electronics.
I have been using the same Lithium battery for the past 6 years now and it still strong with much better cranking power and 10 times lighter, I will never go back to regular battery.
There's allot more good options nowadays, you can look up Shorai, WPS, Featherweight, Antigravity and more.
But, definitely upgrade the R&R if you have't done it yet, there is plenty of great info on doing that here.

 

I use the Shorai LFX18A1-BS12, same battery going on 3 years now. Just needs to make sure you have the charging system to support it. If you are not getting 13.8 or higher at the battery id not use a lithium

 

I replaced the rectifier a couple of years ago so I should be good to go. Thanks for the brand and model number. When I do a search for batteries for Super hawk, no one seems to includdd lithium batteries. Thanks again.
