Gobel Power REPT 345Ah LiFePO4 Cell Review — Is It Worth It? [2026]
.jpg)
REPT 3.2V 345Ah LiFePO4 Cell
A higher-capacity prismatic cell than the common 280Ah/314Ah standard, rated for 8,000 cycles at 80% depth of discharge, sold through Gobel Power.
Is the REPT 345Ah cell worth buying?
If you're building a larger pack and want more capacity per cell than the common 280Ah/314Ah sizes, yes — 345Ah cells mean fewer cells (and fewer connection points) for the same total capacity. At $804 each, this is priced for serious DIY builders and installers, not casual hobby projects, and the 50–60 day delivery window from China needs to be planned around.
A step up in capacity from the common cell sizes
Most DIY LiFePO4 packs are built around 280Ah or 314Ah prismatic cells, but REPT's 345Ah cell offers more capacity in a similarly sized case — useful if you're trying to hit a specific kWh target with fewer total cells. Gobel Power positions it for professional energy storage systems, high-demand backup banks and modular pack building.
What makes this cell stand out
345Ah per cell, ~1.1kWh stored energy
Each cell is rated for 345Ah at 3.2V nominal, storing roughly 1.1kWh — noticeably more than the 314Ah cells common elsewhere in Gobel Power's catalog, which can mean fewer series-connected cells needed to hit a target pack voltage and capacity.
8,000 cycles at 80% DOD, over 96% efficiency
REPT rates the cell for 8,000 cycles at 80% depth of discharge, with a round-trip efficiency above 96% — both solid numbers for a high-capacity prismatic cell aimed at daily-cycling solar or backup applications.
≤0.3 mΩ AC impedance, 0.25C standard rate
Low AC impedance keeps heat generation down, though the standard charge/discharge rate is capped at 0.25C — a bit more conservative than some 314Ah cells, meaning it's tuned more for steady, sustained discharge than high-burst applications.
UL, CE, MSDS and UN38.3 documentation
The cell carries UL, CE, MSDS and UN38.3 certifications — UL in particular is a step beyond the CE/UN38.3/MSDS combination found on some other cells in Gobel Power's lineup, relevant if your project or region specifically requires UL-listed components.

Pros & Cons
Pros
- 345Ah capacity is higher than the common 280Ah/314Ah cell sizes, reducing cell count for the same pack capacity.
- 8,000-cycle rating at 80% DOD and over 96% round-trip efficiency are both strong specs.
- UL certification alongside CE, MSDS and UN38.3 covers a broader compliance bar than some competing cells.
- Low AC impedance (≤0.3 mΩ) supports efficient sustained discharge.
- Fits standard DIY pack-building workflows for anyone already sourcing a separate BMS and case.
Cons
- 50–60 day delivery from the China warehouse is a long wait compared to EU or US-stocked options.
- 0.25C standard charge/discharge rate is more conservative than some other cells, limiting burst current use.
- At $804 per cell, a full 16-cell pack is a serious investment before adding a BMS and case.
- No BMS or case included — this is a raw cell purchase only.
Answers before you buy
Why choose a 345Ah cell over the more common 314Ah size?

A capacity-focused option for bigger builds
The REPT 345Ah cell isn't for small projects — it's for builders who want to hit a large kWh target with fewer cells and are willing to wait out the long shipping window. The cycle life and efficiency numbers back up the higher price per cell.
