I feel like no. Id like to know why if so as in what damage could be done?** A: There will be no damage jumping a car from this battery. Only part that is at risk is the dead lead acid battery, that likely needs replacing regardless. However, you should not use one of these 12v LFP's to replace your lead acid. Alternators do not make stable power to charge lithium batteries. **Q: The 2 50ah batteries are mounted in series in the pride mobility scooter to power a 24 volt motor. Charging is via a 3 pin xlr connector. What charger** A: To charge 24V 50Ah battery system, the DC charging voltage should be between 28.4V~29.2V, and charging current less than 50A. **Q: Could the 300ah 12v be used to start a 3 cylinder 23hp diesel engine?** A: Since our battery is not a car battery, we do not suggest using it as a start-up battery. Our battery will be more suitable for house batteries. You could also kindly offer more details of your application, and I could see whether we could offer some suggestions to you. **Q: No low temperature cut off? I see replies both yes and no. Which is it?** A: Hi there, thank you for your inquiry. Unfortunately, the 12V190Ah battery does not have a low-temperature cut-off function. However, we have upgraded 12V100Ah and 12V200Ah with an auto-heating function that may fit your purpose. The auto-heating battery can be charged at ambient temperatures of -4°F/-20°C. I hope this helps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Power Queen 200AH Lithium battery *by D***N on January 9, 2026* This battery is as described with no obvious defects.

This seller personally called me to check on my purchase (it may have been in broken english from an Asian lady but damn, that’s service). I was honestly flying blind on whether three 12.8v batteries wired in series would mess up my 36v golf cart but for the last two weeks it hasn’t caused a single problem. Make note that if you’re replacing a ton of 6volt batteries in your golf cart that the bracket under them (or at least on my EZGo) doesn’t match up for a longer battery. The batteries are super light. The value for the money is 100% there. The battery life is insane. Okay, I know it’s rigged up in my picture, deal with it! I have to get the bracket cut and welded to fit, once I get that done I’ll clean up the wires and make it pretty under there. As for longevity- I bought that meter because I wasn’t sure if the stock one in my golf cart would work with these batteries. It didn’t drop below 100% and I’m not really sure if that’s due to the nature of how these batteries supply 100% of their power and then just die (which they haven’t done yet)… but… my kids have driven the golf cart around for 4+ days in a row without charging them once. With the previous batteries we had to charge them after each partial days use. Not much else to report on. They work awesome and this seller is awesome. Update - The batteries have died after 4 days of use in the golf cart. I have contacted the seller and will update the review accordingly as the process progresses! ## Frequently Bought Together - Power Queen 12.8V 300Ah 3840Wh LiFePO4 Battery, Built-in 200A BMS, Lithium Battery 2560W Power Output, Up to 15000+ Deep Cycles, 10-Year Life, Perfect for Solar, RV, Marine, Off-Grid - Power Queen 14.6V 40A Lithium Battery Charger, Intuitive Charging Values & 3 Status LED Display, Fast Charging Automotive 12V Battery Charger Maintainer for Lithium Battery with 4 Protection Functions - Renogy 500A Battery Monitor with Shunt, High and Low Voltage Programmable Alarm, Range 10V-120V up to 500A, 20ft Shielded Cable, Compatible 12V Lithium Sealed, Gel, Flooded Batteries,Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/488245300-12v-300ah-lifepo4-battery-3840wh-lithium-battery-with-2560w-power](https://www.desertcart.vn/products/488245300-12v-300ah-lifepo4-battery-3840wh-lithium-battery-with-2560w-power) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-21*
