This battery is VERY light and has held up well on days with multiple starts on a Yamaha 60 2 stroke. I would recommend getting a LiTime charger for this battery to top off the charge the night before you go out on the boat, using the LiTime charger i think gives this battery the best shot at lasting a decent amount of time vs using another brands generic LiFePo4 charger. Even if you get 2-3 years out of these batteries I think they are worth the price as they are 1/4th the price of a Dakota or similar "on-brand" battery. Size: The size is compact and is very light, I was able to get more storage space and take weight off my skiff to help with draft with just changing the battery to one of these LiTimes, I also have the trolling motor battery thats 100ah and have really enjoyed the weight savings to help me get shallower. Functionality: The 20ah rating this battery has I believe is true and not inflated, I run speakers and GPS off this battery with the motor off pretty often and sometimes for for a few hours and havent killed the battery yet so it does have good battery life. It has plenty of cranking amps to start my yamaha 60 2 stroke and I would think a 4 stroke 60hp would do well with this battery also.

Used for Tohatsu 30hp 4 stroke outboard motor as starting battery and it works well. Battery is so much lighter than my old deep cycle AGM starting battery.

Bought this battery on sale four months before I was able to use it. Took it out twice, each time it shut down. Went and had a load tested. The person testing said I don’t know what’s wrong with this thing but it just shut down. Got in touch with lifetime they just told me I have the wrong battery and that I shouldn’t use it for yamaha motors. Lost $80 for their return policy

The 100ahr batteries by liTime are fine for the 36v trolling motor on my boat but not recommended as a starting battery. The 12v 20ah is the battery for starting the 250hp suzuki on my boat and it works just fine It is smaller and lighter than my previous group 31 agm battery.

It's a big battery it's longer than a standard battery tray so it will require modification. But it's a very nice battery so far. I like the Bluetooth feature where you can check the status and litime has good customer service.

Bottom line up front...these are awesome batteries! I replaced all my boat batteries with Li Time and never had an issue with them. They save weight and they run forever. Customer support is excellent and will answer all your questions if you have concerns about how they will work for your application. I had two for a 24v trolling motor and this one for the cranking (175 HP motor) and house battery. My only issue is the price has gone up significantly and I can't justify upgrading my new boat with these batteries.

Did some upgrades on my boat and replaced all the batteries with LiTime lithiums. Was a little unsure on this battery but took a chance. So far so good! Starts the motor great and runs the other things connected to it. Seems to recharge itself pretty well from the motor even though the motor is a 2004 model. Charges fast with the new Noco bank charger I installed on the boat.
