RJ-LFP-12M75-S
Factory Price - Powerful CCA Performance - Extremely Reliable
RJ TECH 12V marine batteries are similar-sized to lead-acid batteries, which makes upgrading to RJ TECH Lithium 12V Batteries a simple task, while offering six times the battery life and less than a third of the weight of lead-acid batteries.
RJ TECH Lithium Batteries are built for starting, with increased peak amps for starting motors, electric start generators and other high-amp-draw devices , lightweight yet, due to their superior construction, they are very strong and durable. They are able to withstand extreme levels of vibrations and shocks and are most suited for military, marine applications.
Features
• Powerful Cold Cranking Current.
• More than 5000 Cycles
• BMS over charge/discharge/temperature protection
• BMS cell balance funciton
• IP66, IP67, water proof, dust proof, Temperature monitoring
• Customization for Size and Discharge and charge rate
• Free of Maintenance, contains no poisonous material
• No leakage, no hazardous chemistry
• Lighter in weight, smaller in size to save space.
• Powerfull to increase robust operation for your marine boat
• Fast charging and high power discharge rate available
• No need to add water nor worry about maintenance.
