Style: 165Ah Starting Battery(1200 CCA)
This battery is above standards I'll never go back to a lead acid battery ever again. The battery came charged up and the app loaded and worked fast without any issues the volts was 13.1 out the box before I even put to charge. The only thing I would change is have slightly longer terminal bolts but u can always buy your own if needed so that's not a issue . Customer service is awesome very respectful, I had another battery I bought needed to be replaced and they did with no questions ask and the shipping was fast within two days I had my replacement. Between the battery and customer service it's worth every penny. The weight of battery is light you can't go wrong with this battery

This is a great battery - flawless in my boat running a 250 pro xs. Litime has incredible customer service and support! I lost one of the insulators on the battery connection and could not find a replacement anywhere. I contacted their customer support service and was pleasantly impressed by the friendly response from Tanya. They don’t sell those items separately, but after listening to my story she went above and beyond to get me a replacement.

Style: 20Ah Starting Battery (800CCA)
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.

Excellent battery and connected to the app easily and with no problem. Easy to see how much battery is left. Used it all day with a16” Humminbird and 2 Canon ultra down riggers and a FishHawk lithium ultra and never came close to running low on battery power. I just put in an order for another one. It’s connected to my Mercury 250 XS and the other one I just ordered is going on the 15hp pro troller.

Be very careful. I called LiTime to get some information for whether this battery would work for my boat. I was assured it did, and bought the battery, along with some other items to make it compatible, per their suggestion. Well, it was delivered and I cannot make it work or pay someone that will even try to make it work. I arrived a week ago, has not been out of the box, and I cannot return it. I would highly recommend NOT buying anything from LiTime.

It works as advertised and the size and quality is good! I’ve used it with several different pieces of equipment and it preformed outstanding! Easy to charge and holds a charge and the power of the charged held up. So I’m very satisfied with the quality and overall performance of the product!

Refunded me the difference in price when went on a better sale a week later. Battery works perfect first trip out. First trip out 5 hours of fishing 3 fish finders and live wells and other power usage and only used 6% of battery capacity. Awesome so far
