Reading the specifications

Detailed specifications for Lion Energy UT 3500-BT-H | 3,584Wh 12V Lithium Battery | Heated + Bluetooth | 150A BMS | 10-Year Warranty have not been published yet. Lion Energy lists this battery in the Batteries, and we add fields as the manufacturer releases them — in the meantime, ask your distributor for the datasheet before ordering.

For a battery, the figures that matter most are communication protocol (CAN or RS485) for talking to the inverter, nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh), usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50% and system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack. Storage is what turns a solar array from a daytime bill-reducer into a system that covers evening loads and rides through outages. It is normally the single most expensive component, so sizing it correctly matters more than with any other part.

Choosing a battery: the checks that matter

The checks below apply to any battery. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.

Leave room to expand. Packs that parallel cleanly let you add capacity later; ones that do not force a full replacement.
Compare usable kilowatt-hours, not nameplate capacity. A 100 Ah lead-acid battery at 12 V is nominally 1.2 kWh but only about 0.6 kWh is safely usable, while a 100 Ah LiFePO4 pack gives you roughly 1.0–1.2 kWh.
Size from your evening consumption. Add up what actually runs after sunset for the hours you want covered, then divide by the usable capacity per unit — that number, not the array size, sets how many batteries you need.
Check the continuous discharge rating against your inverter. A battery that stores plenty of energy but can only deliver 50 A cannot support a large inverter at full output.

Where buyers lose money

Mixing old and new batteries, or different chemistries, in one bank. The weakest unit drags the whole bank down and can be damaged by the others.
Sizing the bank for total daily consumption rather than after-dark consumption, which typically doubles the cost for no benefit.
Installing lithium packs in an unventilated, hot enclosure. Sustained high temperature is the fastest way to lose cycle life.

Price and availability in Saudi Arabia

Lion Energy UT 3500-BT-H | 3,584Wh 12V Lithium Battery | Heated + Bluetooth | 150A BMS | 10-Year Warranty is listed at $ 2,099 (USD) for Saudi Arabia. Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.

SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in Saudi Arabia: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Lion Energy locally before ordering.

Lion Energy UT 3500-BT-H | 3,584Wh 12V Lithium Battery | Heated + Bluetooth | 150A BMS | 10-Year Warranty — frequently asked questions

How much does Lion Energy UT 3500-BT-H | 3,584Wh 12V Lithium Battery | Heated + Bluetooth | 150A BMS | 10-Year Warranty cost?

Lion Energy UT 3500-BT-H | 3,584Wh 12V Lithium Battery | Heated + Bluetooth | 150A BMS | 10-Year Warranty is listed at $ 2,099 (USD) for Saudi Arabia. The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.

Who makes Lion Energy UT 3500-BT-H | 3,584Wh 12V Lithium Battery | Heated + Bluetooth | 150A BMS | 10-Year Warranty?

Lion Energy UT 3500-BT-H | 3,584Wh 12V Lithium Battery | Heated + Bluetooth | 150A BMS | 10-Year Warranty is a Lion Energy product, listed under batteries with model reference 50170186. The Lion Energy brand page lists the rest of its range so you can compare across the catalogue.

Is Lion Energy UT 3500-BT-H | 3,584Wh 12V Lithium Battery | Heated + Bluetooth | 150A BMS | 10-Year Warranty right for my system?

That depends on what it has to connect to. For a battery, check communication protocol (CAN or RS485) for talking to the inverter, nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh) and usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50% against the rest of your equipment before price enters the decision. Check the continuous discharge rating against your inverter. A battery that stores plenty of energy but can only deliver 50 A cannot support a large inverter at full output.

Where can I buy Lion Energy UT 3500-BT-H | 3,584Wh 12V Lithium Battery | Heated + Bluetooth | 150A BMS | 10-Year Warranty in Saudi Arabia?

SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer in Saudi Arabia — buying in-channel is what keeps the manufacturer's warranty valid.
