Our take on the Seatec Group 8D RB24V100 Lithium Iron Phosphate Deep Cycle Battery, 24V, 100Ah

The Seatec Group 8D RB24V100 is a 24V, 100Ah lithium iron phosphate (LiFePO4) deep cycle battery built in the Group 8D case size. That makes it a drop-in option for boats, trolling motors and off-grid systems that already run 24V lead-acid banks. LiFePO4 delivers far more usable capacity and cycle life than flooded or AGM batteries of the same rating, and it weighs much less than a comparable lead-acid 8D. The 100A continuous discharge limit suits moderate loads; high-draw inverters and big thrust motors may want a higher-current BMS.

Pros
  • Full 100Ah usable capacity, unlike lead-acid's 50% rule
  • LiFePO4 chemistry gives long cycle life
  • Group 8D footprint fits existing trays
  • Lighter than an equivalent lead-acid 8D
  • 100A continuous discharge covers most 24V loads
Cons
  • 100A BMS limits high-draw inverters and large motors
  • Needs a lithium-compatible charger or charge profile
  • Cold-weather charging must be restricted below freezing
  • No smart monitoring or Bluetooth app

Questions and answers

Can it replace a 24V lead-acid 8D battery directly?
Yes, it uses the same Group 8D case size and 24V nominal voltage, so it drops into most existing trays and wiring. You will need a charger with a LiFePO4 profile, since lead-acid charging voltages are too high.
How much of the 100Ah can I actually use?
Nearly all of it. LiFePO4 tolerates deep discharge, so you can run close to 100Ah before the BMS cuts off, versus about half that on a lead-acid battery.
Can I run a 24V trolling motor or inverter on it?
Moderate loads are fine within the 100A continuous limit. Large inverters or high-thrust motors that pull more than 100A continuously will trip the BMS, so check your peak draw first.
Can it be charged in freezing weather?
Charging below 0°C damages LiFePO4 cells. Unless the BMS blocks cold charging, keep the battery above freezing before you charge it.
Does it have Bluetooth or a battery monitor?
No. There is no app or built-in shunt, so add an external battery monitor if you want state of charge and current readings.
What charger should I use?
A 24V lithium charger with a LiFePO4 profile, typically charging to around 28.4–29.2V absorption. Avoid chargers with lead-acid equalization modes.
