Frequently asked questions
Does this battery include self-heating?
The inbound pallet information identifies the stocked batteries as self-heating. The heating function assists low-temperature charging according to TWS operating instructions. Confirm the exact label and model before fulfillment.
Can I monitor the battery from a phone?
Current TWS documentation lists BLE communication and the MyTWS app. Supported information can include operating data, battery status, diagnostics, events, and other functions. App features may vary by model and permissions.
Can I connect multiple batteries?
TWS documentation lists a maximum of three matched units in series or eight in parallel. Use only approved accessories and an engineered wiring/protection plan. Contact ULS before ordering or installing a multi-battery system.
What charger should I use?
Use a charger with a LiFePO4 profile that matches the battery's required voltage and current limits. Confirm the charger model, charge profile, communication needs, and low-temperature behavior before use.
Is this a universal RV, marine, solar, golf-cart, or starter battery?
No universal compatibility is claimed. Those applications may be possible only when system voltage, current, charger profile, physical fit, communication, external protection, and warranty eligibility are confirmed.
What warranty applies?
Warranty support is coordinated through United Lithium Solutions under the published TWS/ULS warranty terms. Replace the warranty link above with the final approved document before publishing a duration or capacity-retention claim.
Installation and safety: Installation should be completed by qualified personnel. Use appropriate cable gauge, torque, insulation, over-current protection, disconnects, and protective equipment. Do not use a damaged, leaking, swollen, overheated, or improperly stored battery.
