    Questions and answers

    What makes Seatec Relion batteries different from lead-acid?
    Relion batteries use lithium iron phosphate chemistry, so they weigh far less than comparable lead-acid banks and deliver more usable capacity. They also accept higher charge currents and hold voltage steadier under load. The trade-off is a higher upfront cost and a need for a lithium-compatible charger.
    Which Seatec battery fits a 24V or 36V system?
    The Group 8D RB24V100 is a single 24V, 100Ah unit for 24V banks. The RB36V40 is a 36V, 40Ah pack for 36V trolling motors and similar loads. The RB52 is 12.8V, so it is wired in series for higher-voltage systems.
    Does Seatec offer a warranty on Relion batteries?
    Relion batteries carry a multi-year limited warranty, typically around 10 years for the deep-cycle line depending on the model. Keep the purchase record, since claims run through the seller or Seatec support.
    Can Seatec lithium batteries be charged in freezing weather?
    Charging below freezing can damage lithium iron phosphate cells, so check whether the specific model has low-temperature charge cutoff. Discharging in cold is generally fine. Confirm the charge profile with your charger's manual before installing.
    Where can I find Seatec battery specifications and manuals?
    Datasheets and manuals are published on Seatec's Relion product pages, covering dimensions, charge voltages and cycle life. Match the model number exactly, since specs differ between the 24V, 36V and 12.8V versions.
    Are there Seatec discount codes?
    Deal.ai checks what Seatec products actually cost at every store, so a real markdown shows on this page as a deal as soon as it starts, and each product's page has its price history to tell a sale from its usual price.
