Top 12V 50Ah LiFePO₄ Battery Manufacturer
Industrial-grade designed, the VTCBATT 12V 50Ah LiFePO₄ battery delivers true-rated 600Wh usable energy with 3,000–8,000+ cycles and up to 10 years of maintenance-free service. Built with Grade-A prismatic cells and a smart BMS, it provides comprehensive protection against over-charge, over-discharge, over-current, over-temperature, short-circuit, low-temperature cutoff, and BMS lockout recovery (pre-charging function).
Compared with traditional lead-acid or AGM batteries, the 12V 50Ah LiFePO₄ battery is only about 1/3 the weight, supports 100% depth of discharge, and allows 1C (50A) fast charging, making it significantly more powerful and efficient in real-world use. The IP67 waterproof, salt-spray-resistant housing ensures reliable performance in demanding environments such as marine, RV, and outdoor applications.
With stable voltage output, ultra-low self-discharge, optional Bluetooth monitoring, and flexible series/parallel expansion (up to 51.2V or 200Ah), VTCBATT 12V 50Ah lithium batteries are widely used in RV systems, solar energy storage, trolling motors, fish finders, mobility scooters, backup power, and portable power stations—offering factory-direct quality, safety, and value you can trust.
Lightweight
Compared with a traditional lead acid battery, a 12V 50Ah lithium lifepo4 battery is only 1/3 of a Lead Acid battery, making your RV, trolling motor lighter and with more energy output.
Ultra-long Cycle life
At 1C charge and discharge, the 12V 50Ah lithium battery lifecycle can still keep 3,000-8,000 cycles. Even after 10 years of use, the battery can still maintain 70% of its original 50Ah capacity without an obvious drop in capacity.
Smart BMS
VTCBATT-branded 12V 50Ah lithium battery is provided with smart BMS against over-charge,over-discharge,over-current, short-circuit,over-temperature,pre-charging function, low-temperature cut-off, and salt spray resistant.
Low self-discharge rate
Featuring an ultra-low 1% self-discharge rate per month, the 12V 50AH lithium battery can be stored for several months without a large voltage drop or over-discharge. Then you just need to charge the 12V 50Ah battery per 6 months without repeated charging during storage or maintenance. Unlike the common trouble in storage of the lead acid battery or AGM battery, the 12V 50AH lithium battery removes your trouble of being overcharged even after a longer period of storage.
Zero Maintenance
A traditional lead-acid battery generates trouble with regular water filling and new battery replacement annually, but you are benefiting a lot from the zero maintenance of the LiFePO4 battery.
-You don’t need to fill water regularly anymore, saving great efforts and time.
-You just need to charge the 12V 50Ah lithium iron phosphate battery every 6 months, per time with 50%-60% SOC.No need to worry about the storage in overdischarging anymore.
-You can use the 12V 50Ah LiFePO4 battery for 10 years without replacing new batteries.
Multi-charge compatibility
VTCBATT 12V 50Ah lithium battery is designed to support multiple charging methods of solar charging, AC smart charging, and a DC-to-DC charger, enhancing its reliability to power off-grid, RV, marine, or backup power applications.
Fast Charging Capability
VTCBATT 12V 50Ah lithium battery can support max 1C(50A) fast charging to allow max energy absorption during peak sunlight hours, reducing the energy waste. The traditional 12V 50Ah lead-acid battery can only allow a maximum 0.2C (10A) charging current, wasting electricity during the peak sunlight. Furthermore, the charging formula of the lead-acid battery in bulk charging, absorption, and floating prolongs the charging time.
Advantages
When chosing the best 12V 50Ah lifepo4 battery for your devices,you may confront the common challenges.
– Suffering from BMS being locked out.
– Can’t get the whole 600Wh energy.
– Don’t know the battery status before usage.
– Can’t use in a trolling motor because the battery is not waterproof.
– Can’t expand the energy by multiple connections.

VTCBATT is designed to address these problems of maintenance-free operation, full usable capacity, intelligent BMS monitoring, flexible expansion capability, and compliant shipping certifications.
When the BMS disconnects the 12V 50Ah LiFePO4 battery output and protects the cells from overdischarge damage, the BMS locks out with no voltage output at the terminals. Under the situation, it will be dangerous to use the high-current charger to charge the batteries directly.
To release the BMS lockout, VTCBATT BMS adopts a tiny pre-charge resistor, which raises the cell voltage slowly in a current-limited path of 0.05C-1C to resume the batteries in a safe way.
The 12V 50Ah LiFePO4 battery is a type of deep-cycle batteries, which allow 100%(1C) deep charge and discharge regularly. Even under a 1C charge and discharge, the battery can still maintain above 2000 + times without significant degradation.This 12V 50Ah deep cycle lithium battery can always deliver stable and continuous power for your trolling motor, marine, fishing finder,off-grid, and backup systems.
The internally integrated Bluetooth enables your on-time APP monitor at any time. You just need to click the APP to get live battery status, historical data logging, customizable SOC alerts, and remote diagnostic of health reports.No need to worry about the power outage without expectation.
VTCBATT 12.8V 50Ah lifepo4 adopts the solid modular construction designed for reliability and safety. The 4S configuration of four 3.2V 50Ah Grade-A and brand-new Lifepo4 cells can not only ensure great cell consistency, but also enhance the ultimate safety.All the cells are securely fixed in precision holders and housed in a standard SLA-size case. The SLA case design with M8 output facilitates your upgrade from a traditional lead-acid battery to a lithium battery quickly, by simple wiring for various applications of RVs, marine systems, solar energy storage, backup power, and off-grid setups.
The 12V 50Ah LiFePO4 battery is provided with an IP67 waterproof case to guarantee the battery’s performance under bad environments of rain, dust, mud, and marine spray.
