Antigravity Small Case 16-Cell 480CA Lithium Ion Battery
The perfect chopper/bobber battery.
This battery is super light weight and compact. Although it is a little bit taller than the AG1201, which is recommended for sportster or engines up to 1200cc's. However, if you live in cold weather like myself (PNW) you need to step it up and buy the 16 cell. The cranking amps are required when you are doing a cold start, otherwise you will damage the battery after attempting to start the bike a bunch of times and possibly drain it, which can also cause damage. Besides, you don't want to be that guy everyone is waiting on to be able to start your bike. Revzilla was cool enough to swap my old battery out for me for free with paid postage.

So far so good harley sportster 1200
I've been using this battery for about a month with no trouble at all on my 2009 harley sportster 1200.

Lightest Battery on the Market!
I have a 2008 HD-VRSCDX (V-Rod) and I am into street-cruise performance so keeping things streamlined and light. So with a OEM lead-acid battery weighing 15.4 lbs and needing replacement a good opportunity to go to something lighter. I looked at all the available batteries and settled on this one. The reason? Only Shorai and Anti-Gravity are waterproof and since I do ride in the rain and my bike gets soaked so those were my two choices. The Shorai is almost twice as heavy. So this small-case 16 cell AG-1601 comes in at 3.2 lbs saving me 12.2 lbs off my bike! Also the battery is nearly half the size of my OEM battery so now I have space in the battery box for other electronics, a small tool-box for road repairs, a tire-patch kit and CO2 canister to re-fill tires, etc.
There are somethings you have to know in going with this battery though. It is a LiFePo4 Lithium battery so it is sensitive to overcharging and over-discharging and you could ruin it if you do any of the two. You can't charge this battery past 14.5v or below 11.0 volts without damaging it. So if your bike has an voltage regulator that provides power outside that range you can't use this battery. Best on a modern motorcycle with a solid-state type voltage regulator.
Also you can't use a regular lead-acid type trickle-charger because the battery can be overcharged or draw too much current and overheat. The battery has little internal resistance so it can charge VERY fast and so draw a lot of current (Amperage# so that must be limited to 4 amps max for saftey #to keep battery from overheating#. You need to have a LiFePo4 "lithium battery smart charger" that you can set the limits on voltage and current. I would set to charge to 13.4V and 4 amps #or less# for fast charge and 13.4V and 1 amp for trickle.
You may have issues jump-starting this battery as well so you should know that. If the voltage left on the battery is 11.5 v or less it is likely to draw more than 4 amps from what ever motorcycle/car battery you connect it to and "smoke" this battery #gets to hot#.
You may also have issues if you have a lot of parasitic voltage loss. In other words, if when your ignition/accessory switch is in the OFF postion if your motorcycle draws power to keep an Electronic Control Unit, GPS, or other device powered even in "sleep" mode you will have some loss. All depends on how much loss and how often you ride. You wouldn't want this to set in a garage all Winter as it would drain down the battery so you could put it on a LiFePo4 trickle charger or you could disconnect the battery terminals for long term storage. This battery can hold its charge to 100% if there is no parasitic losses for a full year! Battery came out of the box with 13.39 volts on it.
Just a tip -- if you have a smart trickle charger and know how much parasitic loss you have you can directly counter that and no more. Say you have 0.034 amps #340 mA# of parasitic loss from your ECU. You can set the charger for 13.4V and 0.5 amps #500 mA# and that should cover it for long term trickle charging.
Box shows thumb-knobs terminal screw-downs and instead mine came with two 6mmx12mm 1mm thread pitch bolts. Not a good idea to use them as this leaves the metal conductive battery terminals fully exposed. I got a couple of thumb-knobs that worked and no charged metal exposed now.
Battery has the equvalent of 480 cold cranking amps and I am sure it could start large engine car. Never heard my bike start so quickly -- LiFePo4 can provide power faster to the starter than any Lead-Acid battery due to lower internal resistance. It is kind of amazing.
