Engineering Answer: When sourcing 202Ah to 304Ah 3.2V LiFePO4 prismatic cells for 12.8V (4S), 25.6V (8S), or 51.2V (16S) deep-cycle battery packs, cells fall into two mechanical families: the 54×174×207mm (54173207) medium-thickness housing used by EVE LF230 230Ah, CATL 230Ah, CALB 230Ah, REPT 230Ah, CATL 202Ah, and Lishen 202Ah, and the 72×174×207mm (71173207) standard ESS housing used by EVE LF280K 280Ah, EVE LF304 304Ah, 280Ah 3.2V Deep-Cycle Prismatic Cell, CATL 280Ah, CATL 302Ah, and REPT 280Ah.

2. Mechanical & Electrical Design Guidelines for 202Ah–304Ah Pack Builders
- Why 202Ah/230Ah (54173207) Excels in Compact RV & Marine Enclosures: At 53.8mm thickness instead of 71.7mm, a 16S row of EVE 230Ah, CALB 230Ah, or Lishen 202Ah saves 286mm of linear cabinet depth while still providing 10.3kWh–11.77kWh at 51.2V.
- Turnkey 280Ah & 304Ah Pre-Assembled Packs: If your project requires UN38.3-certified complete battery packs with integrated Smart BMS, see our 48V 304Ah Ultra-Capacity Home Storage Battery Pack, 48V 280Ah Rack LiFePO4 Battery Pack, and 24V 280Ah Deep-Cycle Marine & Power Station Battery.
