Ecolite 12.8V 304Ah Lithium Iron Phosphate Battery 4000+ Cycles Maintenance Free

Product Overview
This LFP12.8V304Ah lithium iron phosphate battery delivers 3891 watt hours of clean and safe energy storage. Built with automotive grade cells and an integrated Battery Management System, it replaces traditional lead acid batteries with higher efficiency, lower weight, and zero maintenance. The 12.8V nominal voltage makes it compatible with standard 12V inverters, chargers, and appliances.

Technical Specifications
Nominal voltage is 12.8V with 304Ah rated capacity and total energy of 3891.2Wh. Cell chemistry is LiFePO4, the safest lithium technology. Cycle life exceeds 4000 cycles at 80 percent depth of discharge while retaining over 80 percent of original capacity. Self discharge rate is less than 3 percent per month. Operating temperature range for discharge is -20°C to 60°C and for charge is 0°C to 55°C.

Key Benefits
This battery weighs significantly less than a comparable lead acid battery while providing full usable capacity. Lead acid batteries only allow 50 percent depth of discharge to avoid damage, so a 304Ah LFP battery effectively replaces a 600Ah lead acid bank. The maintenance free design eliminates watering, corrosion cleaning, and acid spills. Fast charging capability reduces downtime for daily cycling applications.

BMS Protection
The built in Battery Management System provides comprehensive protection including overcharge protection, over discharge protection, over current protection, short circuit protection, and temperature based cut off. Cell balancing ensures all internal cells remain at equal voltage for maximum cycle life and safe operation.

Applications
This 12.8V 304Ah battery is ideal for solar energy storage systems, RV house banks, marine trolling motors and house loads, off grid cabins, floor cleaning machines, electric golf carts, and backup power for telecommunications equipment. It also works as a drop in replacement for lead acid batteries in mobility scooters, lift gates, and industrial equipment.

Installation Tips
Mount the battery on a flat stable surface indoors or in a weather resistant enclosure. The case is not fully waterproof, so avoid direct rain or submersion. Use appropriately sized cables rated for the expected current draw. For inverter applications, match the inverter’s recommended battery cable gauge. Connect the positive terminal first then the negative terminal. Ensure the charging source is set to lithium profile with absorption voltage between 14.2V and 14.6V and float voltage around 13.8V.

Charging Requirements
Use a CC CV charger designed for LiFePO4 batteries with bulk charge voltage of 14.2V to 14.6V. The recommended charge current is between 30A and 150A depending on your charging source. Maximum continuous charge current is typically 150A for this capacity class. The BMS will disconnect charging if voltage exceeds approximately 14.8V.

Discharge Performance
Continuous discharge current is sufficient for most 12V inverters up to 3000W to 4000W. Peak discharge current for motor starting or surge loads can reach several hundred amps for short durations. The BMS will protect against excessive current draw. Voltage stays flat around 13.2V for most of the discharge curve, providing stable power to sensitive electronics.

Cycle Life and Longevity
With proper charging and within temperature limits, this battery provides more than 4000 cycles. For a system that cycles once per day, that represents over 10 years of service before reaching 80 percent of original capacity. Even after 4000 cycles, the battery remains usable for less demanding applications. Calendar life is typically 10 to 15 years regardless of cycle count.

Dimensions and Weight
Exact dimensions are not listed in the image, but typical for a 300Ah class LFP battery is approximately 330mm by 170mm by 220mm (LxWxH) and weight around 30 to 35 kilograms. Terminal type is usually M8 or M10 studs suitable for ring terminals. Confirm detailed measurements from the product datasheet before installation.
