Howell Energy expands deep cycle LiFePO4 battery line for solar and RV use

Howell Energy Co., Ltd. is promoting a certified LiFePO4 battery lineup for solar, RV, marine and off-grid applications, with models spanning 12V to 74V and capacity options up to 300Ah. The company says the packs are designed for lighter weight, longer cycle life and direct drop-in replacement in common battery trays, with UL, CE, IEC 62619 and UN 38.3 compliance.

Why it matters: - Solar, RV and off-grid builders need battery packs that are lighter, last longer and fit existing systems without redesign. - Howell Energy is positioning its LiFePO4 lineup as a replacement for lead-acid and AGM batteries in mobile and stationary energy storage. - The product range is aimed at distributors, integrators and vehicle makers that need certified packs for international markets.

What happened: - Howell Energy Co., Ltd. announced deep cycle LiFePO4 battery pack solutions ranging from 12V to 74V. - The company says its LiFePO4 production lines have been in place since 2006. - Howell Energy says it operates from production facilities in Jiangsu and Dongguan. - The lineup is built for off-grid solar systems, recreational vehicles, marine use and traction power.

The details: - The HWE-4F100 12V 100Ah battery weighs about 12.0 kg. - Howell Energy says that is about one-third the weight of a comparable 100Ah lead-acid or AGM battery. - The battery uses LiFePO4 chemistry and comes in an IP65-rated sealed enclosure. - The pack is rated for operating temperatures from -20°C to 60°C. - Howell Energy designs casings to BCI Group 24, Group 27 and Group 31 dimensions. - The HWE-4F100 is meant to drop into existing marine and vehicle battery trays without compartment retrofitting. - Standard M8 terminal posts support connections to inverters, solar charge controllers and DC distribution blocks. - The batteries deliver 100% usable depth of discharge. - The company says the cells support 3,000 to 5,000 deep charge-discharge cycles at 80% depth of discharge. - Howell Energy says the discharge curve stays above 12.8V across 90% of the discharge period. - The voltage profile is intended to support loads such as air conditioners, induction cooktops and refrigeration compressors. - Howell Energy says automated grading matches open-circuit voltage within millivolt tolerances and AC internal resistance within milliohm limits. - Each finished pack includes a Battery Management System. - The BMS supports continuous 100A current and peak surge loads up to 200A. - The protection system covers overcharge, overdischarge, overcurrent and external short circuits. - Cell balancing circuitry redistributes charge during the final charging stage. - The broader product line includes 12V, 24V, 36V, 48V, 60V, 72V and 74V nominal ratings. - Capacity options run from 100Ah to 300Ah. - The HWE-4F100 supports up to 4S4P configurations. - Howell Energy says that can be used to build 48V 400Ah storage banks. - The full lineup complies with UL 1642, UL 2054, CE, IEC 62619 and UN 38.3. - The company offers customized casing dimensions, terminal layouts and communication protocols. - Sample orders can start at one piece for field testing. - Howell Energy says technical teams provide engineering assessments and project proposals within 12 hours. - Standard warranties run from one to two years. - Integrated energy storage systems can qualify for five- to 10-year coverage. - Shipments can be arranged under EXW, FOB, CIF or door-to-door DDP terms.

Between the lines: - Howell Energy is emphasizing certification, modularity and drop-in compatibility to reduce adoption friction for buyers moving away from lead-acid. - The pitch is also aimed at global procurement, where safety standards and shipping documentation can determine whether a battery can be sold or installed. - Direct factory sourcing is presented as a way to cut distributor markups and stabilize supply for larger projects.

What's next: - Howell Energy is directing integrators and vehicle makers to its technical datasheets and multi-inverter protocol manuals. - The company is also steering buyers to its international engineering portal for specifications and quotation support: technical portal. - Howell Energy says it will continue supporting customized projects through direct factory consultation and lifecycle support.

The bottom line: - Howell Energy is betting that lighter weight, long cycle life and broad certification will make its LiFePO4 packs attractive for solar, RV and off-grid power systems.
