VMAX LFP battery modules consist of high-quality cells, components and a custom designed BMS giving them many advantages including:

Recommended Charging Options:

Use a VMAX AGM Charger* or a LiFePO4 Smart & Microprocessor controlled charger with the recommended specs above.
<15V alternator if used in vehicle or marine application.
Compatible Lithium Charge controller if used in solar applications.
Charge at Max Charging current only in situations when fastest charging rate is needed. Not recommended on an ongoing basis.
Do not Recondition Lifepo4 batteries.

* VMAX Charging time for a fully discharged 50AH battery:

Recommended uses:

Trolling Motors, Solar Power Backup, UPS, Portable Devices, Medical Cart Applications, Camping, Trailers, Boats, and most deep cycle applications.

NOT RECOMMENDED for engine start applications.

Parallel wiring is acceptable for up to FOUR batteries.

Series wiring is acceptable for up to FOUR batteries.

BCI Group Codes:

Matching Termination: U1 (+ on L.H.S. & - on R.H.S)

Battery comes with carrying handles that may vary in shape and color.

* Matching is based on closest dimensional specifications.
