Lithium Battery Packs Built On Grade A Cells And A Smart BMS

Sike Power builds LiFePO4 packs for residential storage, telecom backup, golf carts, RVs and commercial ESS - 32 of them, each with its published capacity, case dimensions, BMS rating, IP rating and cycle life on the page. Only brand-new grade A cells and top-brand smart BMS go into them, and the after-sales complaint rate has stayed below 0.05% for five years.

What we build

Eight Battery Groups For Storage Backup And Traction

12V and 24V lead-acid replacements, wall-mounted and stackable home storage, 19-inch rack modules, 48V telecom backup, golf cart and automotive-case packs, and liquid-cooled commercial ESS cabinets. Each group is organised around the decision a buyer actually has to make: the tray it fits, the bus voltage, the hold-up time or the expansion path.

The range

Sixteen Packs From Across The Catalogue

Two from each group, to show how the specifications are written. The full list of 32 is on the products page, with no pagination and nothing held back.

Where they go

The Applications These Packs Are Built For

Six sectors, each with its own failure mode and its own reason for choosing one pack over another.

Residential Solar Storage

Powerwall, stackable and rack mount 51.2V storage for homes running solar self-consumption, tariff shifting or full off-grid.

RV And Camping Power

12V and 24V LiFePO4 house banks from 100Ah to 400Ah, IP65, Bluetooth monitored, at about a third of the weight of lead-acid.

Marine And Trolling Motor Batteries

12V and 24V deep cycle packs for trolling motors, electronics and house loads, IP65, 3000+ cycles.

Telecom And Data Centre Backup

48V rack packs at 50Ah, 100Ah and 200Ah for base stations, exchanges and DC plant, 6000+ cycles, parallel to fifteen units.

Golf Carts And Low-Speed Vehicles

48V and 72V 100Ah packs plus automotive-case 12V batteries for carts, LSVs and light EVs, IP67, 3500+ cycles.

Commercial And Industrial Energy Storage

Liquid-cooled 215 kWh and 232 kWh all-in-one cabinets, plus 51.2V modular banks for smaller commercial sites.

What we solve

The Four Problems Behind Almost Every Enquiry

None of them is solved by a lower price, and all four are answered on the product pages rather than in a conversation.

A Datasheet That Only Gives Amp Hours

Capacity is the easy number. The BMS current rating, the IP rating, the case dimensions and the depth of discharge are what decide whether a pack fits and survives. Every product page here publishes them.

Cells Nobody Will Name

Grade B cells are cells that failed a consistency test. A pack built from them looks identical on day one and drifts apart over its first hundred cycles. We use brand-new grade A cells and a top-brand BMS, and we will say so in writing.

A Pack That Does Not Fit The Tray

Group 24 at 260x170x210 mm, group 31 at 330x172x240 mm, H7 at 315x175x190 mm, H8 at 359x177x188 mm. The mechanical fit is published because it is the part that stops an upgrade dead.

Capacity That Cannot Grow

Every 51.2V product parallels: stackable modules to 30 kWh, powerwall packs to 120 kWh, telecom modules up to fifteen units. The second phase is a module, not a new system.

Manufacturing

Cell Grading Assembly Aging Test And Inspection In House

Production and offices sit together at the BAK Industrial Park in Da Peng New District, Shenzhen, which is why a process question gets answered the same day instead of being relayed to a subcontractor.

How we work

Five Ways Buyers Use This Factory

OEM And ODM Battery Manufacturing

Your brand on the case, your protocol list, your packaging - with a sample approved before the bulk order runs.

Cell And BMS Selection

Grade A cells and a top-brand smart BMS, chosen for the duty cycle rather than the price sheet.

Capacity Sizing And Expansion

Size the bank from the load, then build it so the second phase is a module instead of a replacement.

Certification And Lithium Shipping

CE, UN38.3, MSDS, IEC, UL and ROHS documents, and packing that satisfies lithium transport rules by sea or air.

After-Sales And Warranty Support

A five-year warranty on the energy storage range, a complaint rate below 0.05%, and engineers who answer the same day.

Selection Guides Written For Buyers

How to size a home battery, how to calculate telecom hold-up time, what a smart BMS actually does, and which datasheet figures are worth comparing.

FAQ

Questions Buyers Ask First

Are you a manufacturer or a trading company?

A manufacturer. Shenzhen Sike Power Technology Co., Ltd. runs its own production plant and offices in Da Peng New District, Shenzhen, with assembly, cell grading, aging tests and final inspection in house.

What do you actually make?

32 LiFePO4 battery packs in eight groups: 12V and 24V deep cycle, powerwall, stackable, rack mount, 48V telecom, golf cart, automotive-case and liquid-cooled commercial ESS cabinets.

What cells and BMS do you use?

Brand-new grade A LiFePO4 cells from top-brand cell makers, with a top-brand smart BMS. That is the whole quality argument, and it is the first thing to ask any battery supplier.

What certificates do you hold?

The factory is stated as ISO9001, ISO14001 and ISO45001 certified. Product certificates listed across the range are CE, UN38.3, MSDS, UL, IEC and ROHS. Ask us for the certificate covering your exact model and market.

Do you support OEM and ODM?

Yes, and most of what we build carries a customer's brand. Case, BMS behaviour, protocol list, label and packaging follow your specification, with a sample approved before bulk production.

How quickly will I get an answer?

Fast reaction is the standard the company sets for itself: WhatsApp is usually answered the same working day, email within 24 hours.

Send Us The Application And The Load

You will get a pack, a capacity and an expansion path rather than a price on its own.
