12V 20Ah Lithium LiFePO4 Deep Cycle Battery, Rechargeable Battery Up to 2000-7000 Cycles, Built-in BMS, Lithium Iron Phosphate for Solar, Marine, Energy Storage, Off-Grid Applications

Great battery. Powered my 8k diesel heater for 10 hors and only used 25% . Was able to camp for 2 nights and it only used half charge.30 amp

Bought two.One was installed in a computer UPS (replacement for SLA 12v) and works great. Check the current reqs for your UPS!The 2nd went into the saddlebag of a motorcycle, to act as an emergency battery booster. Very light!Note: this is not a motorcycle cranking battery. In the case of extended cranking (out of gas, carb problems, cold weather), it can be attached in parallel with the onboard lead acid, to partially recharge the cranking battery, and then support 12v while cranking. Get yourself a 10ga connector like used on solar panels or a battery float charger, to make connection in the field quick and easy. Lead acid batteries can suffer instant death, I'm too lazy to push start.Note: Honda Goldwings are notorious for failing to fire the ignition below 11v, using this battery as a "boost" worked the trick when night time temps whacked the cranking battery and prevented starting.

Replaced my Yamaha RDS250 Sea Scooter battery with this (cannibalized the proprietary connector from the old battery and added normal F2 compatible connectors). Works great so far. Will update review if that changes.This battery exactly fits the Sea Scooter and is the same size as the OEM AGM battery.The OEM Sea Scooter Casil AGM batteries are specially modified versions to add catalysts to absorb hydrogen production and not vent the gas dangerously into the sealed case, as would normally occur with a standard battery. So it is not safe to use off the shelf AGMs in a Sea Scooter. However, LiFePO4 does not vent gas and has no such safety issue. Note that the Scooter takes 14.5A, so you do want a LiFePO4 battery that can handle the load. This battery can, and we've been running it hard in the pool today.Only down side over the OEM battery is it's not as heavy and so your Scooter will be more buoyant than usual. For pool party use that's no problem, you can still dive down with it, you just need to use more power to hold it under. For actual scuba diving, you're going to need weights to make it neutral.But at almost 1/3rd of cost of the OEM battery, 33% more capacity, and 10x longer life (if you store/maintain it properly), this is a big improvement.

Works great for led light bar

So ill do a review because I ran this battery to zero (you can do that with lithium) I didnt see any reviews with this information in it. if you run it all the way to zero the battery will report zero volts. It is not dead. You simply need to jump it and add a little 12volts to it for 3 seconds. That will give the BMS time to start up and it will report 10 volts. Then it will take a charge.Good battery Nice capacity and a good weight. I love mine. Ive had it a year now. Just killed it and learned that you just have to give it some juice to get it to start. It isnt dead.Enjoy!

I purchased this battery in August 2024 for my BMW R1200C, relying on Amazon's "Sure Fit" compatibility. However, the battery did not fit. The posts were on opposite sides of what my motorcycle required. I ended up giving it away. Be cautious with the "Sure Fit" application; it was incorrect for my model.

Very happy so far. Bought two of the 200Ah models to start a solar battery bank to replace some aging deep cycle lead acid batteries. They had an $80 coupon at the time making each $320 bucks which is cheaper than buying 200AH of lead acid batteries. They seem well constructed. They are each about the same size as two 100AH deep cycles but weigh about a quarter as much as they would. They have sturdy rope and and plastic handles for toting them where you need to. Don't have to worry about specific gravity, distilled water, sulfuric acid or leaky batteries or any of that nonsense anymore. I feel like I travelled into the future. Only took a few minutes to get them setup and charging and most of that was changing the charge controller on my solar system to Lithium. I don't know if they'll last ten thousand cycles (sounds like something from Farscape) but they should last way longer than lead acid science experiment that was out there.

I have been loving this little guy. It is so light that I can carry it with one hand while carrying my other equipment! I never could do that before. It is used for our regular power outages and I use it to power the TV occassionally. I have charged it from a zero percentage charge a few times and it seems to be going strong. It's been a few months now. I have bought other Goldenmate products so I definitely have been pleased with them.
