GOLDENMATE 12V 100Ah LiFePO4 Battery, Up to 15000 Deep Cycles Group 31 Lithium Battery, Built-in 100A BMS, Perfect for RV, Solar, Camping, Marine, Trolling Motor and Off-Grid Applications

Great battery at a good price. I'm glad I got the version that has Bluetooth as my trolling motor don't have the ability to accurately display the charge levels on LiPo batteries. I chose the 100 amp hour battery and it should give me about 6 hours of runtime on my 46 lb trolling motor running between 40-60%. I haven't tried it on the water yet, however, I did run the motor inside a large trash can filled with water and testing was excellent. It was during my tests that I discovered I HAD to make use of the Bluetooth as my motor kept displaying 100% charged. I am incredibly impressed with the Bluetooth as the app is super easy to use and set up and provides all the pertinent information including anticipated runtime based on the current discharge rate. FYI: The App you use is GOLDENMATE. I'm not sure why this information isn't included in the description and Amazon's Rufis couldn't find this information. This made it necessary to contact their Customer Service and within a short time, I was chatting with one of their representatives on a Saturday evening. (24/7 is their support which is awesome!) Another nice feature about the app is that it not only shows expected runtime, but also expected charge time as well based on rate of charge. YES, you DO want to use a charger designed to work with LiPo batteries. These (types) of batteries are extremely light compared to lead acid batteries and have a much longer lifespan as well. The only thing not perfect with the battery I got is that one of the clips for the battery strap was broken so I cannot use the strap. In my case, the battery will be kept inside a rain proof battery box (container) so I can lift it with the handles on the container. My Use: This battery will be the main source of power for my 10' Intex Mariner 4 inflatable dinghy with 46 lb trolling motor. When my little (project) boat is complete, it will have carpeted wood floors, Bimini top, carpeted bow & stern storage areas, bow & stern cleats for anchor lines, 2 rolling, swivel fold down seats, rod holders, running lights, interior lights, storage for tools, mini cooler, tackle box, and life jackets. I may also rig up a clear tarp to attach to the front of the Bimini top and bow of the boat for additional protection from rain. (I live in Florida which means frequent scattered showers and of course, 100% humidity!) In summary, I was a bit disappointed with the strap tab being broken, but the excellent 24/7 customer support and the very helpful app made up for this one little flaw.

Decent capacity, lightweight, works great for multiple uses, when paired with a battery box works great for camping and running a small inverter. Good value for price/capcacity, Battery is well made and ha sturdy connections. Simple to setup and add to backup power supply.

Have had it about a year, probably at about 25 cycles on it. Use it mostly for a trolling motor on a kayak. Can run for hours at full throttle will no loss of power. Also handy to use for other 12v needs. Super light so makes it easy to use. Only gripe is it's difficult to know the state of charge. I just know my motor draws 10amps so I have about 5hours run time. Same goes for charging, you just keep charging it until the internal computer won't take a charge anymore. Helps to have an intelligent charger so you can keep track of how much you think you used vs how much went back in. Lots of batteries out there but this seems to be a good brand.

The battery so far works very well. It fits in my small boat nice. Pretty easy to set up the Bluetooth app. On the app where it shows the percentage of the battery charge in my opinion is to large. This takes up to much space that could be used for other data for you to see. You be able to see all at one time. The app does work. The works well with my LiTime 20ah battery charger. It is pretty light for a full size battery. Did not weigh it but feels like 20lbs. Do not rely on the built in battery handle. Mine broke but luckly it was not that high up so no damage to the battery but the handle is none function now. The company did refund me 10% of my purchase price but handle still not work. I would not buy this if you want to rely on a handle. If it was not for the handle and the one thing on the app I give it a 5 star. I guess for th price should not complain to much $155. They do sale batteries with better handles, but more money.

Perfect for my camper trailer. Survived 3 days without a charge. Being able to check the power level is very convenient

Just installed replace Sokerdy which died in less than 2years. Not happy that right after purchasing they started offering $50 coupon. UPDATE-changed to 1 star This battery is losing capacity rapidly since purchased in Sept 2025. Initially charged to full. Battery charged to 14. 2v and charger would quit at this point. Max charged amps was: - 63.4 Amps 11/30/25 -70.2 12/07 -73.9 12/11 -78.1 12/13 -87.3 12/23 -96 12/31 -108.9 1/10/26 -112.6 1/14/26 Battery was synced/changed to 0 fully charged by solar charger at this point. That's battery capacity down 112 amps. Too late to return but I do not recommend this battery.

Took out the two Group 24 RV batteries in my RV and installed this. It's lighter, longer-lived, and has more capacity considering that it can be discharged much deeper than a lead-acid battery before the voltage drops too low. With a 255-watt solar panel on the roof and an MPPT charge controller in lithium battery mode, I never need to run the generator, which is a good thing since lithium batteries are not designed for the cranking amps to start a gasoline engine. And if you don't use a solar charge controller to keep your lithium battery charged you must do something about your rig's converter and alternator which don't get along well with lithium batteries. On shore power the converter will cut out before the battery is fully charged if it's not lithium-aware, and on the road the battery may pull too much power from the engine's alternator if it's very low on charge.
