12V 100Ah LiFePO4 Battery

The pack line's dual-duty build: 1,280Wh of storage with a published 1,700CCA cranking rating — one battery for electronics and engine-start duties.

The 12.8V pack family carries several capacities, and the 100Ah build is the interesting one: alongside its 1,280Wh of storage it publishes a 1,700CCA cold-cranking rating with a sub-3-second peak — specified, in the manufacturer's own words, to run all your electronics needs and crank an engine. That dual duty is why this model has its own page: it serves the vehicle and equipment builds where one battery does both jobs.

The family context matters for specification. The same 12.8V line includes a 6Ah compact pack (90 × 70 × 107mm, 0.75kg), a 30Ah general model and a 120Ah build, sharing a 3,000-cycle-plus rating at 80% DOD, self-discharge of 3% per month or less, and published connection rules — up to four in parallel and four in series on the family, with the standing note that series and parallel connection at the same time is not recommended.

Charge guidance is printed in C-rates: 0.2C recommended, 0.5C maximum, with a 10.0V discharge cut-off calculated at 2.5V per cell. Discharge runs −20°C to 60°C. The 100Ah model uses an F2 terminal in its published build; its 120Ah sister uses M8. Equipment makers designing this pack in should treat the product page figures as the starting specification and confirm the production build — terminal, case, labelling — in the written quote, which is how this factory handles every pack order.

Why It Earns Its Place

Features

Storage and cranking in one unit

The 1,700CCA rating covers engine-start duty that ordinary storage packs refuse — one battery, one locker, one maintenance line.

Family depth behind it

6Ah to 120Ah on the same platform means a product line can standardise on one supplier from sensor packs to house banks.

Published connection rules

Series and parallel limits — and the warning against combining both — are printed, not discovered.

Design-in discipline

Terminals and case are confirmed per production build in the quote, the way OEM supply should work.

Where the 100Ah build fits

Dual-battery vehicles, marine and RV house banks with starting duties, portable power equipment and solar kits that need a standard-case 100Ah unit. Buyers who need pure deep-cycle RV capacity at larger sizes should look at the RV line (230–640Ah at 8,000 cycles); buyers who need a standard pack that can also crank should start here.

Ordering & OEM

How ordering works

Minimum order quantities and lead times depend on the product type and the degree of customisation: standard products can start from smaller batches, while custom housings, labelling and packaging are assessed per project. Samples can be arranged, with sample and freight costs confirmed against the requirement. Every enquiry is answered with a written specification and quote stating the model, configuration and terms - nothing about an order here is left to chat messages.

Improve Battery runs OEM/ODM alongside its standard range, and ships with the export documentation each model carries (CE, RoHS, FCC, MSDS, UN38.3 types as listed per datasheet; certificates available upon request). State the model, voltage, quantity and destination in the enquiry form and the sales team in Shenzhen will reply with the full specification.

Questions

Frequently asked

Is the weight really under a kilo?

The manufacturer's datasheet lists the 100Ah (1700CCA) build at 0.75kg — identical to the 6Ah line in the same table, which reads as a publishing inconsistency. We do not print a corrected guess: the quote confirms the production weight before you design around it.

Can I parallel four for a 400Ah bank?

The family publishes support for four in parallel. Matched units and the communication arrangement are confirmed in the quote.

What terminal does it ship with?

The published build lists an F2 terminal. Terminal configuration is an order-level item — state your requirement in the enquiry.
