LiFePO4 Solar Battery

Built for Solar Cycling, Not Just for Starting

Solar storage is a different duty cycle from engine starting or backup float service. A battery bank on an off-grid system is asked to absorb uneven charge from PV arrays, hold energy through cloudy stretches, and deliver steady current to inverters and DC loads — often every day for years. Hysincere LiFePO4 solar batteries are engineered around that reality.

Since 2013, Shenzhen Hysincere Battery Co., Ltd. has designed and manufactured lithium iron phosphate battery packs from our Shenzhen headquarters and Dongguan production base. As a China National High-Tech Enterprise, we build the cells into packs, design the BMS in-house, and control the assembly process end to end. Our energy storage products ship to Europe, the Americas, Australia, Japan, South Korea, and Southeast Asia, serving RV, marine, golf cart, home energy storage, industrial, and lead-acid replacement applications.

Why LiFePO4 for Off-grid Solar

Long cycle life. A representative product such as the LF12100-S-T50 (12.8V 100Ah / 1280Wh) is supplier-rated for ≥4500 cycles (test conditions to be confirmed). Cycle performance must be evaluated together with duty profile and procurement cost before any total-cost-of-ownership comparison.

Stable voltage through discharge. LiFePO4 holds a flatter voltage curve than lead-acid, so inverters and charge controllers see fewer low-voltage cutouts during long overnight discharges.

Deep-cycle tolerance. Off-grid systems rarely recharge to 100% every day. LiFePO4 chemistry handles partial state of charge better than lead-acid, which sulfates under the same pattern.

Sealed and maintenance-free. No watering, no off-gassing in the living space — a practical advantage for RV, marine, and cabin installations.

Voltages and Form Factors for System Designers

We supply solar storage packs at the voltages off-grid integrators actually specify:

• 12V — small cabins, RV house banks, trolling motors, candidate for lead-acid replacement
• 24V — mid-size off-grid systems, telecom cabinets, light industrial
• 48V — home energy storage, larger arrays, inverter-based systems

Enclosure formats include the LF12100-S-T50 with an IP65 case and integrated Bluetooth monitoring for state-of-charge visibility, the LN12100N-BL sodium-ion 12V 100Ah / 1200Wh option for buyers evaluating alternative chemistries, the GF51105N-B 48V 105Ah pack for golf cart traction, and the EF51200W-L wall-mounted storage unit for residential installations.

Pairing with Solar Charge Controllers

Every Hysincere LiFePO4 pack is managed by a BMS we design ourselves. The BMS protects against overcharge, over-discharge, overcurrent, short circuit, and temperature extremes — the conditions a solar charge controller is also trying to manage. For system designers, the practical points are:

• Set the charge controller to the absorption and float voltages specified in the pack datasheet, not to lead-acid defaults
• Confirm the controller's charge profile matches LiFePO4 requirements, or select a controller with a lithium mode
• Size the array so daily harvest fits within the pack's recommended charge current
• Account for low-temperature charging limits if the installation sees freezing conditions

Because we control BMS firmware and pack assembly, we can adapt communication protocols and cutoff parameters for OEM and ODM projects.

OEM/ODM and Technical Support

Hysincere supports custom voltage, capacity, enclosure, and BMS configurations for solar integrators, distributors, and equipment manufacturers. Our technical route covers LiFePO4, sodium-ion, and solid-state development. Certificates are available upon request, and our engineering team works directly with customers on charge profile matching and system integration questions.
