Winnebago Sprinter Ekko 23B 320ah 2nd Battery Upgrade Kit by FreedomVanGo

320 amp hours (4096 watt hours) These are very high quality lithium batteries.  State-of-the-art lithium battery with integrated NeverDie® Battery Management System (BMS) to ensure the batteries are operated within their rated specifications. Unlike many competitors which offer lower quality MOSFET based BMS designs, Lithionics uses heavy duty contactors for BMS on/off switching controlled by a custom microprocessor. Small form factor – a great way to squeeze the most battery capacity into a small space like a van – much smaller than using a bank of “typical” 100 amp hour batteries. Integrated heater for charging/discharging in all climates and conditions. Built-in Bluetooth allowing you to monitor battery voltage, state-of-charge, temperature, current, and status code from the Lithionics iOS or Android app. Kit Includes:  GTX – 320 Amp Hour Lithium Battery by Lithionics Battery Tie Down Tie Down Bolts Battery cables Install Video Here:
