Features
- Longer Lifetime12V 7Ah LiFePO4 batteries provide over 2,000 deep cycles, significantly exceeding the lifespan of standard lead-acid batteries, which offer only 300-500 cycles. With the ability to discharge up to 100%, our 12V 7Ah lithium batteries extend usage time between replacements and yield considerable cost savings.
- Built-in 7A BMS Protection Each of our 12V 7Ah lithium batteries is equipped with a built-in 7A Battery Management System (BMS) that includes six crucial safeguards: high temperature, overcharge, over-discharge, overcurrent, short circuit, and auto balance protection. This ensures not only durability but also safety in various applications.
- Series and Parallel Connection12V 7Ah LiFePO4 batteries allow flexible wiring options, including series connections to create a powerful battery bank system of 24V/36V/48V. You can also connect them in parallel to achieve capacities like 12V 16Ah/24Ah/32Ah, accommodating up to 16 batteries for a total capacity of 1433.6Wh.
- High Energy DensityOur lithium batteries have higher energy density and are lighter, weighing 60% less than traditional sealed lead-acid batteries, which makes the device more portable, requires less effort to carry, and allows for more flexible installation.
- Wide Applications12V 7Ah lithium battery is an ideal replacement for less durable SLA batteries, suitable for diverse applications such as fish finders, home alarm systems, solar water pump systems, amateur radios, and more. Note that this battery is not designed for starting engines.

I’m using this 12V 7Ah LiFePO4 in a small power setup (lights + occasional small load) and it’s been reliable so far. The biggest difference vs lead-acid is the steady output—my devices stay happier instead of sagging quickly. Charging has been consistent, no weird behavior, and it feels like a well-made pack for the size. If you need a compact battery for ride-on toys, fish finder, or a small backup power box, this is a good choice.

12V 7Ah LiFePO4 Battery is solidly built, with tight positive and negative terminal connections, and is ready to use right out of the box. It reacts incredibly quickly during power outages, maintaining stable and consistent brightness. The battery life fully meets expectations, and most importantly, it's durable. The capacity shows no significant change after multiple charge and discharge cycles, lasting much longer than traditional batteries. It offers excellent value for money!

Update after 3 weeks. After a few cycles the UPS shows green battery light. All good now, updating rating from 3 to 4 stars. Still very high battery pack IR, and the 5A limit due to BMS. ===original review=== Charged to full then drained down to 3.15v/cell (12.6v pack) at 1A, got only 5.5AH. If discharging all the way down to 3.2v maybe it can go 6~6.5AH, but 6AH is likely the realistic capacity. 5A BMS printed on casing, seller also confirmed the pack is capped at 5A. So it's only good for loads up to 60W. I tried putting 4 batteries in a series, and put them in an APC SMX750 UPS. The UPS keeps saying battery faulty with red light constantly on. The BMS is likely not tuned for series in UPS. Though it still works since it has the capacity, just be careful about the maximum load it can take. Very high IR. Checked 4 out of the 13 batteries purchased, they all are 190~210 ohm. I haven't taken one apart to actually check the cells; maybe just the BMS but not sure. Can also be old/low-quality cells. I got them just 10~20% more expensive than SLA, so I guess they're passable when at about the same price of SLA. Can't say I would recommend them unless they are in deep deep sale, like 80% of the price of SLA. Maybe just spend a little more to get the 12v 9AH lifepo4 instead (just 2 bucks more than this one).

I’m using it to power my fish finder on a kayak, and it works flawlessly. Lightweight but powerful, with very stable voltage throughout the day. It lasts much longer than my old lead-acid battery and charges quickly. The built-in BMS gives great protection, and the compact size makes it easy to mount. Excellent choice for anglers looking to reduce weight without sacrificing performance.

Si las conectas en paralelo no funciona ya que si bms es muy barato tube cambiarlo para que funcionará bien por suerte yo tenía la bms y la cambie y funciona muy bien. El producto es bueno pero el bms es malo si se conecta en paralelo se bloquean y tienes que desconectar y conectar de nuevo
