Batteries & Storage
Wide-Temperature Batteries & Storage
Lithium, sodium and LTO cells, packs and storage — engineered from −50 °C to +80 °C for off-grid solar, remote power and cold-start, where a normal battery stops.
Quick Answer
Wide-temperature lithium batteries charge and discharge far outside the range of a normal cell — from about −50 °C to +80 °C — which is what off-grid solar in hot deserts, cold-climate monitoring, and vehicle cold-starting actually need. The range covers LFP cells (18650/26650/prismatic 100–200 Ah) with the longest cycle life, high-energy Li-ion NMC (18650/21700, to 290 Wh/kg) discharging to −40 °C, 12–48 V packs for solar and off-grid, cold-cranking APU starting batteries, high-voltage 5 kW/380 V storage, plus LTO (15,000 cycles) and sodium-ion. GZ Visions sources them from a qualified Chinese maker certified to UL1642, IEC 62133, CE and UN38.3, matches the chemistry to your climate, qualifies each order before you pay, and handles dangerous-goods export documentation — with the factory named to you only at the order.
Most lithium batteries quietly fail at the edges: they will not charge below freezing and they age fast above 45 °C. That is exactly where remote-power projects live — a solar system in a desert averaging over 50 °C, a monitoring station at −30 °C, a truck that has to crank at dawn in the cold. This line is built for those edges: wide-temperature cells and packs that charge and discharge from −50 °C to +80 °C, tested through hundreds of cycles in high-low temperature chambers and certified to UL1642, IEC 62133, CE, UN38.3 and GB18287 — the certificates that gate export by air and sea.
The range is deep. Wide-temperature LFP and Li-ion cells in 18650, 21700 and 26650 formats and large prismatic 100 Ah / 200 Ah, with LFP grades running −50 °C to +80 °C and high-energy NMC to 290 Wh/kg discharging down to −40 °C. Finished 12 V, 24 V and 48 V LFP packs with CAN/RS485 and Bluetooth for solar and off-grid. Cold-cranking APU starting batteries pushing roughly 1,600 A for trucks and heavy vehicles. High-voltage energy-storage modules at 5 kW / 380 V, over 6,000 cycles, on- or off-grid. LTO batteries good for 15,000 cycles and 1C charging below −30 °C for AGVs and cold-chain, and sodium-ion cells and starting batteries for low-cost cold-weather power.
The desk sources these through a qualified maker with its own cell and pack lines, matches the chemistry and format to your duty cycle and climate, and builds the price to a landed DDP number where it can. Every order is qualified before shipment — payment tied to inspection — and the factory is named to you at the order, not before. Because these ship as dangerous goods, the desk handles UN38.3, MSDS and the export documentation as part of the job.

Quality, Named Honestly
Pick the chemistry the job needs
Safest chemistry and the longest cycle life (>2,000–4,000 cycles). The default for storage, solar and daily-cycling packs; wide-temp grades run −50 °C to +80 °C.
Highest energy density (to 290 Wh/kg) and high discharge for drones, tools and compact packs. Wide-temp grades discharge down to −40 °C.
LTO for 15,000 cycles and −30 °C fast charge (AGV, cold-chain). Sodium for low-cost cold-weather cranking and power.
The desk quotes the grade you ask for — and tells you when a cheaper grade would fail the job, or a dearer one is money you don't need to spend.

FAQ
Frequently Asked Questions
- What makes a battery 'wide-temperature', and why does it matter?
- A normal lithium battery will not charge below freezing and ages quickly above about 45 °C. Wide-temperature cells use different anode materials and electrolytes so they charge and discharge from roughly −50 °C to +80 °C, holding useful capacity and cycle life at the extremes. It matters wherever the power source lives outdoors and unattended — desert solar, arctic monitoring, high-altitude sites, and cold-start vehicles — where a standard battery simply stops.
- Which chemistry should I choose — LFP, NMC, LTO, or sodium?
- LFP is the safe, long-life default (over 2,000–4,000 cycles) for storage, solar, and anything that cycles daily. NMC gives the highest energy density and high discharge for compact, weight-sensitive products like drones and tools. LTO is the specialist for very long life (15,000 cycles) and fast charging in deep cold. Sodium-ion is a lower-cost option for cold-weather cranking and power. Send the duty cycle, the temperature range, and the size limit, and the desk will match it.
- Can these batteries actually be shipped internationally?
- Yes — the cells and packs are certified to UN38.3 with an MSDS, which is what makes lithium legal to move by air and sea, plus UL1642, IEC 62133, CE and GB18287. Batteries ship as dangerous goods, so the desk handles the UN38.3 report, MSDS, correct packaging and the export documentation as part of the order rather than leaving you to sort it out at the port.
- Can you build a custom pack — voltage, capacity, BMS and communication?
- Yes. Packs are configured to your system — 12 V, 24 V or 48 V (and high-voltage modules to 380 V), the capacity you need, with a BMS covering over-charge, over-discharge, over-temperature and short-circuit, and CAN, RS485 or Bluetooth communication where the application calls for it. High-voltage storage modules parallel up to twelve units and run over 6,000 cycles. Give the desk the system voltage, the usable energy, and the environment.
- Can you size a battery bank for an off-grid solar system?
- Yes. Give the daily energy use, the array size, the autonomy days you want, and the site's temperature range, and the desk sizes an LFP or LTO bank to match — down to a wide-temperature grade if the site runs hot or cold. High-voltage storage supports on- and off-grid operation and works with the major PV inverter brands, so the bank fits the inverter you already run.
