Customer Reviews for MIGHTY MAX BATTERY ML100-12LI - 12 Volt 100 AH Deep Cycle Lithium Battery

delivery date deception, I am the owner and operator of a sprinter, they are on my delivery date, the system indicated 3 days, it has been 6 days and there is no response, I have lost days, I have a project, there was no information about the delay, I went to the customer service counter. customer and no one gives me an answer, I stopped requesting the batteries through another platform because because of uome sport it was faster and I have stopped making more than 5000 dollars now I have to make a decision or continue waiting or go 1 month without having power and not having comfort or asking for another platform what a disappointment

Battery worked well at first, then went "dead" or close to it. I found a loose connection(my fault)..I texted support site for this company and this specific battery re:how to charge it..vague answers("use a 30amp charger") and by web-surfing discovered it's a bit more complex than that with a lithium lead phosphate battery..thanks but I'll look elsewhere for help

Customer service sucks, warranty sucks. I bought these for my boat trolling motor and returned them do not buy if you want to hook them in series for 24v you can not hook them together.

This is a very good LiFePO4 battery, ideal for my RV power system upgrade. I bought two. The batteries appear well made. After some initial testing, I find that their power storage capacity is as advertised. I like how lightweight they are, compared to the AGM Lead Acid batteries I've been using.

Will be reordering again

I replaced my two travel trailer batteries (group 24 FLD) with this lithium battery. I have a solar charging system (Renogy LI charge controller, 400W (4x100) solar panels). I observed the charger/panels delivered about 1.2 kW on the first day via the charger blue tooth application and it appears the battery "soaked" it all up (the charger parameters were changed to the default lithium charger parameters). I will be observing it's ability to power the furnace, lighting, and water pump through the night, the goal is to boondock for a longer time. Additionally, I will be replacing the trailer charger/converter for a LI version.

Haven't had a chance to hook them all up in parallel but I am using one of to power up my 4-channel amp powering up my 8 speakers. Over 4 hours run time and the battery is still at %100 so I cannot complain much. I am so far very please. I plan to buy a total of 12.
