YTX7A-BS Lithium Motorcycle Battery 12.8V 4Ah 350CCA High Performance Lithium Powersports Battery with Smart BMS, Compatible Motorcycle, Scooter,ATV, UTV, Snowmobiles,4 Wheeler, and Generator Battery

Awesome little battery, feels like a sheet of paper in weight, but packs a big punch. Using it on a Cub Cadet I bought last year whose battery died before the mowing season was even close to being over. Only used once, hoping for multiple years use from it. UPDATE: The display stopped working on it after the second month of use, but the battery still works great. Hope it keeps chugging along.

Warning this battery is not a true 14.6 V battery and cannot hold a full charge. I have two dedicated smart chargers and I’m very familiar with Lipo batteries. My brand new unit that just arrived will not charge past 13.7V yes that is technically a full charge but a fresh battery should go to the full 14.6 if it is good quality brand new in the box would it not? So either the battery is defective or Old I contacted Amazon and they said they cannot send me a replacement battery unless I pay for the shipping and send the battery back package of the battery in the box that I ripped open by the way because I did not think a brand new product would be defective….. or I can print out a label and ship it back myself which I would have to buy packaging as I do not have a heavy duty cardboard box for a small 10“ x 10“ battery laying around to ship it highly flammable combustible material all I wanted was a replacement battery that would hold a proper charge. That’s it. I should not have to jump through hoops and use my money for their defect. The packaging was not damaged or anything like that. It is just a poor quality product.

Worked great. No problems

This battery really supplies power at the rated voltage. Voltage does not drop like the lead acid type does. ( what I expected from a lithium battery). It has the cranking power and keeps the input voltage constant during power surges on the inverter I installed on my UTV. Lost one star because the first battery’s built in volt meter switch was broken. But 5 stars to Amazon for the quick replacement at no charge !! I don’t see the advantage of the voltmeter built in to the battery case. Most batteries are located where it won’t be visible and most battery strap down would cover the voltmeter or the switch. Kind of useless 95% of the time. I will see how it works out in the frozen north country this winter. ( I understand lithium batteries do like it below zero very much).

It installed easily with the built-in threaded terminals, and the LED voltage indicator on top is a cool feature. It arrived at 13.0v and initially couldn't start my R1 the first time, which it's notoriously difficult to start. On the 3rd try it started, and then 2 days later it started the first time. It weighed a little under 2 lbs, which was still like half lb lighter than the old lithium (Battery Tender) battery. Let's hope it's durable during cold morning starts at the track.

Amazing technology this battery is so light and powerful. I’m using it in a different application. I have a lawnmower that won’t crank over with a lawnmower battery because the compression release lobe on the cam is probably shot put this battery in fires up. It’s beautiful save a Of labor and work. I wish that lawnmower batteries would have 700 cca

I bought the battery in November worked fine plenty of starting power, then in January, the battery was dead would not take a charge. Seller has not gotten back to me on reimbursement or issuing a new battery as this one is defective. Amazon is refusing to do the same after three days of continuous contact, they refused to do anything.

I have a 2012 Dyna 103 with Andrews 54H cams and needed more crank power in cold 40f or below weather to turn over. Installed new HD battery in spring and now needed to jump in 50f or lower morning weather. ACR's good and wanted to try lith. Batt. After 5 minutes of charging stright out of box with lithium charger it indicated full and had a resting voltage of 13.66v on Fluke meter. installed it this morning at 50f and cranked faster rhen HD batt did when new ever even when hot. Battery arrived yesterday and put on my multi mode charcer in li mode and showed full charce in 5 minutes and resting voltage of 13.6v, after fully charging old AGM batt it restef at 12.5. As of most of my 16 bikes other I have. After the fastest cranking speed it has ever had even when warm and instant start, the he charging voltage was at 14.51v at idle at 1000rpm and at 14.83v 3000rpm. After a +50 mile ride and several starts all good first day. Day 2- Checked resting voltage with Fluke meter 13.62v. Cranked and started instantly, also didn't have to reset gear position/RPM display as I almost always had to do before. The only issue I had is was I needed to shim between the top of battery and the battery box to keep the battery display button from inadvertently being pressed.
