    Lastly, know that there are substantial differences in how to replace lead acid batteries with the “drop in replacement” types of lithium batteries from what a manufacturer would do if designing a lithium house battery bank from scratch.

    In the replacement case you are largely stuck with your existing wiring, appliances and recharging capacity. In the design from scratch case one would almost always use much higher voltages to reduce wire sizes, reduce system amperage and provide much higher wattage per unit of weight and physical size for the battery bank. That would almost always require new/different wiring, devices, system controls and recharge strategies.

    These will likely be the batteries needed. For those in the frozen north, the LT Relion has an internal heater. The HP versions are for higher amp demand such as starting a generator with house batteries, a standard setup in many Fiberglass coaches.
