Frequently Asked Questions

Before You Order

Can I replace my lead-acid battery with LiFePO4?
In many applications, yes, but voltage, charger compatibility, current requirements, dimensions, mounting, terminals and equipment controls must all be confirmed before installation.
Can these batteries be connected in series or parallel?
Select battery models support series, parallel or series-parallel configurations. Always follow the limits listed for the exact battery model and use properly matched batteries, cables, protection devices and installation practices.
Do all models include Bluetooth and an LCD display?
Features differ by product configuration. Confirm Bluetooth, display, communication and application compatibility on the individual product page.
Can I use my existing lead-acid charger?
A charger with a compatible LiFePO4 charging profile is recommended. Verify the required charge voltage and current for the exact battery before use.
What battery should I choose for my equipment?
Provide your equipment voltage, motor or inverter rating, peak current, desired runtime, available dimensions and connector requirements. A battery specialist can then help match the system correctly.
Are self-heating batteries available?
Self-heating is available on selected configurations. Confirm the feature before ordering when the battery will be charged in low-temperature conditions.

Ready to Upgrade Your Battery System?

Shop the 12V and 24V TWS LiFePO4 lineup or contact United Lithium Solutions for help matching voltage, capacity, discharge current and installation requirements.

Product features, ratings, compatibility, warranty coverage and configuration limits vary by model. Review the individual product specifications before purchase and use a qualified installer for multi-battery or high-current systems.
