Buying lithium batteries in bulk can be a headache if you don’t know what to look for. You’re probably thinking: Will these actually work when I need them? Are they safe? And can I get enough without supply issues?

This 7S2P 24V 100Wh 18650 battery pack is built for exactly that. Small backup power, emergency lights, quick bursts when the main power goes out—stuff like subway signal lights or low-power devices. It’s compact, reliable, and sits there ready to jump in whenever you need it.

Backup and Emergency Power, Made Simple

Here’s what you’re getting:

• Voltage: 24V nominal (7 cells in series), keeps things steady
• Capacity: 4.17Ah, 100Wh total
• Configuration: 7S2P — 7 in series, 2 in parallel, each cell around 2.1Ah
• Max Current: 4.2A (2.1A per cell), handles continuous draw no problem

Works well for:

• Short-term backup for subway signal lights
• Small emergency lamps
• Low-power industrial instruments or backups

It’s not a massive powerhouse, but for short bursts it’s rock-solid. Light, compact, easy to install—basically, the kind of battery you don’t have to stress about.

Safety That Actually Matters

Safety is a big deal, especially when you’re buying in bulk. Here’s why this pack keeps you covered:

• Built-in short-circuit, overcharge, and over-discharge protection
• Tested to handle high and low temperatures
• Optional BMS lets you monitor every single cell
• MSDS / UL certificates available if you need them

Whether it’s powering subway lights or a little emergency lamp, this pack gives stable, safe short-term power without headaches.

Bulk Buying Made Easy

If you’re buying a lot, here’s what makes life easier:

• Reliable supply: big orders? No problem.
• Customizable: tweak voltage, capacity, or BMS to fit your setup
• Support: 12–24 month warranty, fast help if anything comes up
• Flexible packaging: easy to ship, easy to store

For bulk buyers, the real peace of mind comes from knowing these batteries work, and that you can scale, replace, or customize them anytime.

Why This Battery Pack Stands Out

• Made for small backup power and emergency lights
• Stable output, compact, installs easily
• Safe and reliable, with optional BMS to watch each cell
• Bulk orders or custom tweaks? Totally doable

Bottom line: If you need short-term backup for subway signal lights, low-power lamps, or small emergency setups, this 7S2P 24V 18650 battery pack has your back.
