ATV UTV Bluetooth Telemetry 20Ah 12.8V Dual Purpose Pack 256Wh Rigid Case

Riders usually discover a weak battery only when the starter button does nothing. This 12.8V 20Ah LiFePO4 pack changes that by putting live battery data on a phone through Bluetooth, while still providing the strong cranking and the deep-cycle reserve that ATVs, UTVs and motorcycles need.

Inside the sealed case, matched LiFePO4 cells feed a management board with a Bluetooth 5.0 module. The pack starts the engine, runs accessories when the engine is off, and reports state of charge, voltage, current, cell balance and temperature to a free iOS or Android app at any time.

Bluetooth State of Charge on Your Phone
The pack carries a Bluetooth 5.0 module linked to the BMS, so a free iOS or Android app shows state of charge, voltage, current, cell balance and temperature in real time. Riders can check the battery before a ride without opening anything, and a low state of charge becomes obvious at a glance instead of being discovered at the starter button.

App Alerts Before Problems Grow
Fault conditions such as over-voltage, over-current or high temperature appear in the app as they happen, and the history log lets owners spot a draining accessory or a weak charging circuit early. Predictive warnings turn battery care into a simple monitoring habit, which is far more useful than guessing why a lead-acid block keeps going flat.

Dual Purpose Cranking and Deep Cycle
This 12.8V 20Ah pack stores 256Wh and delivers a 750A cranking burst for ATV, UTV and motorcycle engines, then handles deep-cycle duty for winches, lights and accessories when the engine is off. It is designed as one battery that can start the machine and run its accessories, instead of two separate packs.

Matched Cells with Active Balancing
Four capacity-matched LiFePO4 cells sit in a rigid bracket inside the case, and the management board balances their voltages during charge so the pack ages evenly. Balanced cells keep the usable energy close to the rated 256Wh for thousands of cycles, rather than drifting apart as unbalanced packs do.

How Bluetooth Changes Battery Care
Without monitoring, a rider finds out about battery health only when the engine will not start. With this pack the app shows the trend long before that: a slow state-of-charge drop, a hot cell group or an over-current event. Compared with a plain 20Ah AGM block, the lithium pack adds live telemetry, doubles cranking authority, saves roughly two thirds of the weight and stretches service life from 500 to 3000 cycles.

ATV UTV and Snowmobile Uses
These 12.8V 20Ah packs fit ATV and UTV starting bays, snowmobiles, jet skis and large scooters, plus off-grid trailers and winch systems that need one battery to crank and to run DC loads. They are also used in camper accessory banks and small solar storage where a compact 256Wh block with Bluetooth monitoring is convenient.

Built for Rough Terrain
ATV and UTV use means mud, water spray, dust and constant vibration. The pack uses a flame-retardant ABS case, shock-absorbing cell padding and spot-welded braced connections, with a sealed top so splash and grit stay away from the electronics. It keeps working where a loose-plate lead-acid battery would fail.

Cold-Weather Cranking
Discharge is rated from -20 to 60 deg C, and the pack keeps most of its cranking current in freezing conditions where a flooded battery would struggle. That matters for snowmobiles, winter ATV work and cold garages that drop well below freezing overnight, and the BMS blocks charging below 0 deg C to protect cell life.

OEM Label and App Branding
WNRLN builds this battery for distributors and machine brands with custom labels, chosen terminal sets, alternative case colours and white-label app branding, so the pack can carry the buyer's own brand and its own monitoring identity.

Frequently Asked Questions

Q: Does the Bluetooth app work when the battery is switched off?

A: The module wakes when the app is opened and the pack is above its shutdown floor, so riders can read the state of charge before a ride. Below the low-voltage floor the board isolates the pack to protect the cells and the module goes quiet.

Q: Can this battery start the engine and run a winch?

A: Yes. It is a dual-purpose design with a 750A cranking burst for starting and an 80A continuous rating for DC loads such as winches and lights when the engine is off.

Q: Is the app subscription free?

A: Yes. The iOS and Android app is free to download and use, and there is no recurring fee for the monitoring data.

Q: Will it fit a standard ATV battery box?

A: The case uses the common 166 x 125 x 175 mm footprint with M6 terminals, so it drops into the typical ATV and UTV tray without modification.
