12V 200Ah custom lithium ion battery pack for solar power and energy storage
A 12V 200Ah pack with a display, built for solar power and energy storage. It doubles the smaller solar pack's capacity and current, and its parameter table is transcribed below from its own listing.

About this model
This pack's listing describes it as a bulk-purchase LiFePO4 battery for solar applications: high-capacity, durable and customisable for efficient energy storage. Its description repeats the same three qualities as the 100Ah pack. Safety and economy: a built-in PCM protection board covering over-discharge, over-charge and short circuit, environmentally friendly with no memory effects. Discharge characteristics: low internal resistance and high flat voltage characteristics during strong current discharge, ensuring a wider application field. Cycle life: long storage life with few limiting conditions, offering problem-free charging after long storage and permitting use in a wide range of applications.
The applications listed for this pack match the 100Ah pack's list: energy storage (UPS, backup and power stations), intelligent robots, electric scooters, solar systems (including wind energy storage, solar and storage home systems and solar street lights), and general energy storage such as backup power, miners' lamps, portable power supplies and digital products. The shared application list is a property of the listing family, not a reason to treat the two packs as interchangeable: the 200Ah pack is larger, heavier and higher-current, and a system designed for the 100Ah pack's space and charger may not suit the 200Ah pack without changes.
The table's most useful rows for a solar buyer are again the capacity, the currents and the size together. A 200Ah capacity at 12V nominal stores about 2400 watt-hours, double the 100Ah pack; a 100A charging current and a 100A maximum continuous discharge current cover larger solar arrays and larger loads, up to about 1200W at 12V; and the dimensions, 521 x 238 x 217 mm at 23.5 kg, describe a pack that needs a planned mounting, not a casual shelf. The display, mentioned in the model description, is a practical advantage for a storage system: the pack's state can be checked without separate instruments, although the listing does not detail what the display shows, and a buyer who needs specific display information should ask for it.

How to read this table
Read the table as a specification for this listing alone. The rated capacity and nominal voltage describe the pack's energy class; the maximum charge voltage and discharge cut-off voltage describe the charger's and the device's voltage limits; the charging current and maximum continuous discharge current describe how fast the pack fills and how hard it can work; the cycle life describes the listing's stated durability; and the dimensions and weight describe the physical pack. No row in this table describes any other model, even one with a similar voltage or capacity.
Two rows deserve a direct question before ordering. The certificate row states what this listing claims, and the certificate set for the exact model should be confirmed in documents, since certificates are available upon request. The delivery and warranty rows state this listing's terms, and they should be confirmed for the exact order quantity, because terms stated for one listing do not transfer to another. A buyer who confirms those two rows in writing has removed the two most common sources of dispute in battery orders.
Confirm before you order
Send the device facts with your inquiry: device type, space, voltage, capacity, peak current, and this model description. Ask for the certificate set for this exact model, confirm the minimum order, price basis and lead time for this listing, and confirm payment and warranty terms before you pay. If the device's space, voltage or peak current differs from this listing, say so in the first line — the custom route, not a forced fit, is the honest next step.

How to place an inquiry, step by step
- Send the device facts. Tell us the device type, the available space (length, width and maximum thickness), the nominal voltage you need, the capacity or runtime you target, and the peak current if your device has motors, radios or heaters.
- Name the model or the chemistry. If a page on this site matches, quote its model description and listing details. If nothing matches, say so and describe the chemistry and voltage you need, so the conversation starts on the custom route.
- Confirm documents and terms in writing. Ask for the certificate set for that exact model, confirm the minimum order, the price basis and the lead time for that listing, and confirm payment and warranty terms before you pay. Terms stated for one model listing do not transfer to another model.
- Agree the sample step. Confirm whether the next step is a listed sample, an engineering sample for a custom design, or a small trial order, and what test you will run on arrival — fit in the enclosure, runtime, or peak-current behaviour.
Send all of this in one message through the contact page: device type, space, voltage, capacity, peak current, model description if you have one, and the documents you need. That is the whole inquiry — no separate form, no account, no extra step.
What to send us now
Send one message with your device type, the space the pack must fit, the voltage and capacity you need, the peak current if it matters, and the model description if a page on this site already matches. Add the documents you need — certificates are available upon request — and whether you need a listed model or a custom design. Use the contact page or write to [email protected], or call +86-755-25629920. A specific message like that is what turns a range of hundreds of models into a short, answerable question.
