Each B4810 is a 51.2V, 100Ah LiFePO₄ module that adds 5,120Wh of storage, connects to the RV5 Power Hub over a CAN data link so the hub always knows its state of charge and limits, and stacks in parallel as your power needs grow. It's the same battery that ships in our RV5 kits — this listing is the battery alone, for expanding an existing RV5 build or starting a custom 48V system.\u003c\/p\u003e\n\u003cp\u003eThe B4810 is IP65-rated and self-heating, so it can charge and discharge down to -4°F (-20°C) — built for rigs that see real winters and real vibration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Specs:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDimensions: 23.94 x 14.96 x 5.71 in.
