Description
The Epoch 36V Essential Series gives you 50Ah of LiFePO4 power in a compact Group 31 battery that’s easy to work into RVs, carts, specialty builds, and off-grid setups. It also comes with built-in heating and Bluetooth monitoring, so it’s ready for more than just fair-weather use.
Key Features
-
Reliable Capacity: Delivers 50Ah and 1.92kWh of stored energy, giving 36V systems a solid amount of usable power without taking up too much space.
-
Self-Heating: Built-in heating helps the battery charge safely in colder conditions, making it more practical for year-round use.
-
Weatherproof Build: The IP65-rated enclosure helps keep dust and water out, making it a good fit for outdoor installs and utility compartments.
-
Smart Connectivity: Bluetooth monitoring lets you check battery status from your phone without having to pull out a meter every time.
-
Compact & Rugged: The Group 31 size fits many standard battery trays, while the ABS and PC blend case gives the battery a tough, durable shell.
The 3650A-H runs on a 12S LiFePO4 configuration and delivers a steady 38.4V nominal output. It supports up to 100A of continuous charging and discharging, with short bursts up to 120A on charge and 130A on discharge when the system needs a little extra.
Its compact size is one of the biggest advantages. At 35 lbs and roughly Group 31 dimensions, it gives you 1.92kWh of storage without forcing you to give up a huge amount of space in a cart, RV compartment, or specialty installation.
Charging is supported from 0°C to 55°C, while discharge operation extends from -20°C to 60°C. Combined with the IP65 enclosure, that gives the battery a pretty wide comfort zone for changing weather and outdoor use.
If you need more runtime later on, up to four batteries can be connected in parallel using Epoch’s plug-and-play configuration. That makes it easy to add capacity without changing the system voltage.
With Bluetooth monitoring, low-maintenance LiFePO4 chemistry, a rugged enclosure, and an 11-year manufacturer warranty, the 3650A-H is a simple 36V battery that gets the job done without adding unnecessary complexity.
