12.8V 200Ah Marine LiFePO4 Battery 2560Wh Bluetooth Smart Fishing Boat 200A BMS IP65

12.8V 200Ah Marine LiFePO4 Battery 2560Wh Bluetooth Smart Fishing Boat 200A BMS IP65

Built for anglers who run trolling motors, livewells and electronics all day, this 12.8V 200Ah marine LiFePO4 battery stores 2560Wh and streams live data to a phone over Bluetooth. A crew can watch state of charge, current draw and cell temperature from the helm or the casting deck, then plan the run home before the pack dips below 20 percent. The 200A BMS keeps twin trolling motors and a fish finder running in parallel without nuisance trips.

Specifications

Core Specifications

The pack runs at 12.8V nominal with a 200Ah rated capacity and 2560Wh of energy. Internal resistance holds at or below 30 milliohms, efficiency reaches 98 percent and self discharge stays under 5 percent per month. Cycle life exceeds 4000 cycles at 1C and 80 percent depth of discharge with 80 percent capacity retention. Cells sit in a 4 series 2 parallel (4S2P) layout. The case measures 483mm long, 170mm wide and 240mm high, weighs 21 kilograms, and uses M8 terminals inside an ABS enclosure rated IP65.

Cycle Life and Longevity of This Marine Battery

A fishing boat that burns 200Ah over a full day can expect this marine battery to last nine to eleven years before capacity reaches 80 percent. Where a 200Ah AGM pack survives roughly two seasons of deep cycling, this marine battery keeps delivering for a decade, so the higher purchase price is repaid within the first replacement cycle and every trip after that is pure savings.

Why LiFePO4 Beats Lead-Acid Onboard

Two 100Ah AGM batteries weigh around 60 kilograms and lose usable capacity within two seasons of deep trolling; this marine battery stores 2560Wh at a fraction of that weight and holds voltage under load. The absence of acid means no fumes in the livewell compartment and no equalisation routine, and Bluetooth data turns guesswork about remaining range into a number on the screen.

Charging Recommendations

Charge this marine battery at 14.2 to 14.6V with 100A recommended or 200A maximum for fast dockside fills. For seasonal storage, leave the pack near 50 percent and recharge every three months, and rely on the Bluetooth readout to confirm the cells are balanced before a long run.

Environmental Tolerance of This Marine Battery

This marine battery operates from -20C to 60C on discharge and 0C to 55C on charge, with a storage window of -20C to 60C. The BMS trips at 65C to protect the cells. Its IP65 ABS shell seals against spray, rain and bilge moisture, and the sealed M8 terminals stay bright through saltwater use.

Communication and Monitoring of This Marine Battery

Bluetooth is built in, so this marine battery reports SOC, voltage, current, cycle count and per-cell temperature to the companion app in real time. The 200A BMS adds overcharge protection at 14.6V, over-discharge at 10V, short circuit shutdown in 300 to 800 microseconds and high-temperature cutoff at 65C, giving the crew an early warning before any cell drifts.

Applications for This Marine Battery

This marine battery fits bass boats, bay boats, walkarounds and pontoons. It feeds 24V and 36V trolling motor banks, livewell pumps, sonar, LED courtesy lights and 12V coolers through long tournament days. Parallel four units for an 800Ah house bank or series-connect for higher-voltage trolling systems without reprogramming the charger.

Installation and Safety of This Marine Battery

Strap this marine battery to a flat, ventilated surface, connect M8 terminals to 8 to 10 Nm and separate the charging source from the load bus. Keep the Bluetooth antenna clear of metal hull structure for a strong app signal, charge only above 0C, and always torque-check terminals after the first run.

Frequently Asked Questions

Q: Does Bluetooth drain the battery when the boat is stored?
A: No. The radio sleeps between polls and draws microamps, so this marine battery can sit for months without a top-up.

Q: Can I charge it with my existing AGM charger?
A: Only if the charger has a LiFePO4 profile at 14.2 to 14.6V. A lead-acid float stage will under-charge this marine battery and shorten its life.

Q: How many trolling motors can it support?
A: A single 200A BMS comfortably runs one main and one kicker trolling motor, or two 24V motors when the bank is series-connected.

Q: Can I leave it connected to the boat over winter?
A: Yes, provided the charger drops to a LiFePO4 float of 13.3 to 13.4V. A maintainer without a lithium profile will over-hold this marine battery and should be unplugged.

Q: Is the app needed to use the battery?
A: No. This marine battery works stand-alone; Bluetooth simply exposes the data the BMS already tracks internally.

Warranty and Shipping

Each 12.8V 200Ah marine battery carries a 5-year limited warranty on defects and 80 percent capacity retention past 3000 cycles. Production takes 15 to 25 days, with Ecolite cartons, foam blocking and export pallets ready for sea freight. We accept L/C, T/T, PayPal and Western Union and quote FOB or DDP as needed.

OEM and Customization

OEM buyers can brand this marine battery with custom case graphics, engraved part numbers and app skins. We adjust BMS thresholds for tournament, solar or hybrid charging and supply a full wiring diagram before production. OEM orders start at 100 units.
