The \"LT\" designation means the battery's integrated BMS automatically prevents charging in sub-zero temperatures, protecting cell integrity and extending battery life in cold environments.\u003c\/p\u003e\u003cp\u003eAt just 3.0 kg — a fraction of the weight of an equivalent AGM battery — the RB20-LT delivers superior energy density, longer cycle life, and consistent performance across a wide temperature range.
