BlueMax Marine 12V 195Ah LiFePO4 Deep Cycle Battery (Group 27)
Stay on the water longer, run every accessory without worry, and crank your engine when you need to — all from a single Group 27 battery. The BlueMax 12V 195Ah delivers true deep-cycle endurance for trolling, house power, RV, and off-grid solar, plus 1500 CCA when it's time to start the motor. Bluetooth monitoring keeps real-time state-of-charge in your pocket.
Why anglers, boaters, and off-grid owners pick BlueMax
- All-day runtime — 195Ah usable capacity means longer trolling runs, more nights at anchor, and fewer trips to the charger.
- Engine starting + deep cycle in one — 1500 CCA hybrid design eliminates the need for a separate starting battery on most rigs.
- Bluetooth in your pocket — Monitor voltage, current, temperature, and remaining capacity from your phone in real time.
- Active cell balancing — Keeps every cell in lockstep for maximum usable capacity and longer pack life.
- Drop-in Group 27 fit — Standard BCI Group 27 footprint slides into existing trays with no fabrication.
Why this beats lead acid
- ~70% lighter than a comparable lead-acid Group 27 (27 lb vs. ~60+ lb).
- 3,000–5,000 cycles at 80% depth of discharge vs. 300–500 cycles for lead acid.
- Use 100% of rated capacity — no need to stop at 50% to protect the battery.
- Flat voltage curve — full power output until nearly empty; no slow trolling-motor fade.
- No off-gassing, no acid, no maintenance — safe for enclosed cabins, lockers, and RV bays.
Built-in NexGen BMS protection
- Overcharge / over-discharge cutoff
- Short-circuit and reverse-polarity protection
- High and low temperature cutoff

Nice and easy install, they work great, much longer range and way better power. Best of all, NO MAINTENANCE
Tried cheaper lithium setups first and they couldn’t handle the amp draw. This one has been solid with no issues.
Absolutely Incredible Range. We replaced our 4 year old Trojan batteries this spring with the 210 AH dual battery kit and we are blown away! We use the buggy to secure the perimeter of a 300 acre lot in South Carolina. We typically put about 200 miles per week on this unit. We have been testing this kit for about a month now and we are getting every bit of 80 miles per charge. Its absolutely unbelievable. Thank you Fleet Lithium!
This screen was so easy to install. We installed our fleet lithium battery about 2 years ago, the screen just came out in April, it took 10 minutes to install and everything works perfectly. Thank you Fleet lithium!
After a few months of use I can confidently say this was worth it. No maintenance, great range, and consistent power every time. Huge upgrade from stock.
I should have just bought this first instead of wasting money on others.
I use my Prowler every day hauling feed and equipment. Other batteries kept shutting down under load. This is the only one that worked right. Glad I spent the money.
Runs strong every time. Exactly what I needed.
The range has doubled compared to my old setup. Installation was straightforward and the instructions were clear. I can now play multiple rounds without recharging.

No more issues with power cutting out. That alone made it worth it.

Handles hills and heavy loads without hesitation. Very impressed so far.
