Product Overview

The workhorse of the 12V range: 200Ah, 2560 Wh, 18.4 kg, with a 200A BMS and expansion up to 4S4P for banks as large as 40.96 kWh. Built with 3.2V 200Ah cells and a smart BMS, it covers RV camping, solar energy storage and off-grid work, and it is the pack most often bought in pairs to make a 400Ah bank or in fours for a 48V system.

Key benefits

Why Buyers Choose This Pack

Expands To 40.96 kWh

The published 4S4P arrangement means this pack is a building block for large banks, not only a standalone battery.

200A BMS At 18.4 kg

Full inverter-capable current from a pack one person can lift into a locker.

2560 Wh Of Real Energy

A published watt-hour figure rather than an amp-hour rating that has to be interpreted.

3000+ Cycles In An IP65 Case

Six to eight times the cycle life of a lead-acid battery of the same nominal size.

Application scenarios

Where It Is Used

RV and camper house banks
Solar energy storage on a 12V or 48V bus
Off-grid cabins and remote installations
Marine house loads and trolling motors
Building blocks for a 4S4P bank up to 40.96 kWh
Backup power for small workshops and offices

Who it is for

The Buyers This Pack Suits

System Builders

Using one pack type as the module for banks from 2.5 kWh to 40 kWh.

RV And Camper Owners

Replacing a pair of AGM batteries with one lighter pack that delivers more usable energy.

Distributors

Stocking the highest-volume size in the 12V deep cycle range.

Problems it solves

What It Fixes

Banks That Cannot Grow

A published 4S4P expansion path means one product covers both a single-battery install and a large bank.

Weight Per Usable Kilowatt-Hour

18.4 kg for 2560 Wh, against a lead-acid pair that weighs far more for half the usable energy.

Undersized BMS On Inverter Loads

200A continuous covers most 12V inverter installations without nuisance disconnection.

Packing and documents

How It Ships And What Comes With It

Packing And Shipping

Packing follows UN38.3 requirements for lithium battery transport, and the carton and pallet arrangement is confirmed with the quotation for your quantity and destination. We do not publish a fixed carton specification here because it changes with order size and freight mode.

Documentation

UN38.3 and the MSDS travel with every lithium shipment, and the certificates listed in the specification table above are supplied for the model you order. Tell us the destination market at the quotation stage so the document set is planned rather than chased after the goods are built. Where a certificate we do not hold is required, we will say so rather than promise it.

Manufacturing

This pack is built at Shenzhen Sike Power Technology Co., Ltd. in Da Peng New District, Shenzhen, with cell grading, assembly, BMS integration, aging test and final inspection carried out in house. Only brand-new grade A LiFePO4 cells and a top-brand smart BMS go into it.

Installation guide

Getting It Right First Time

Step 1

Check the locker against 502 x 186 x 240 mm before ordering.

Step 2

For a series or parallel bank, tell us the target arrangement so the BMS behaviour is confirmed for that layout.

Step 3

Match packs by model and state of charge before connecting them together.

Step 4

Use LiFePO4 charge profiles on every charging source, and a DC-DC charger from an alternator.

Step 5

Fuse each parallel pack individually rather than relying on one fuse for the bank.

Comparison

How It Compares In Our Range

The mid-range 12V packs differ mainly in capacity, case and BMS rating.

FAQ

12V 200Ah LiFePO4 Deep Cycle Battery Questions

What does 4S4P mean in practice?

Four packs in series to make a 48V string, and four of those strings in parallel - 16 packs for 40.96 kWh. Tell us the target configuration and we will confirm the BMS and wiring requirements.

Can I use two in series for 24V?

Series connection is supported within the published expansion arrangement. Confirm the configuration with us before ordering so the BMS behaviour is right for your layout.

Is 200Ah enough for an RV?

For a fridge, lights, pump and modest inverter use, usually yes for two to three days. Send the appliance list and we will work it through.

How heavy is it?

18.4 kg, against roughly three times that for the lead-acid capacity it replaces.

What is the charge time?

At 0.5C to 1C acceptance, one to two hours from a charger that can supply the current. Solar systems are usually array-limited.

Which certificates apply?

MSDS, UN38.3, CE, ROHS and UL.
