Product & Packaging Details
Q: Do batteries include protection circuits(BMS) and connectors?
A:Protection: We supply batteries with BMS built in Protection Circuit Modules (PCM).
Connectors: We normally use standard like anderson,M8 lugs,Fast plugs or depends on OEM customer's demands.
Q: Are batteries Grade-A and brand new?
A: Yes, we use 100% brand new, Grade-A cells in all our batteries.
Q: Can you print our logo on the batteries?
A: Yes, we offer free custom logo printing with a minimal MOQ requirement.
Q: What is your standard packaging? Can it be customized?
A: Our standard is a white box per battery. We fully support customized packaging, including carton box and logo design.
Yes. CMX Battery is a manufacturer located in Shenzhen, Guangdong, China. It designs and produces LiFePO4 battery packs for energy storage, electric forklifts, marine applications, golf carts, RVs, and UPS systems.
Lead time depends on the product: standard battery packs are typically 15-25 days, while larger integrated systems such as our mobile EV charging units are 35-45 days. The exact schedule is confirmed in your quotation.
The company has strategic cooperation agreements with top manufacturers like EVE and REPT, and insists on using A+ tier One lithium iron phosphate cells for its solar batteries.
For 48V inverters, compatible brands include Victron Energy, Goodwe, Studer, Solis, LuxPower, and others. For high-voltage three-phase inverters, compatible brands include Atess, Solinteg, SAJ, Goodwe, and Solis.
CMX Battery offers dealer customers a 10-year warranty and technical service for its energy storage battery products.
DoD describes how much of the battery's capacity has been used. A DoD of 100% means the battery is completely empty, while 0% means it is full.
SoC reflects the battery's charge level. A SoC of 100% means the battery is full, and 0% means it is empty.
C-rate, or power factor, indicates how quickly a battery can be charged or discharged relative to its capacity. A rating of 1C means the battery can be fully charged or discharged in one hour.
The battery uses Lithium Iron Phosphate chemistry and provides a cycle life of over 6,000 cycles at 90% Depth of Discharge, and over 10 years at one cycle per day.
kW (kilowatt) is a unit of power, measuring the rate of energy production or consumption. kWh (kilowatt-hour) is a unit of energy, measuring the total amount of work done or energy used over time.
CMX Battery home batteries are suitable for both indoor and outdoor installation (depending on the model's protection level) and offer floor-standing or wall-mounted options. Common locations include garages, attics, or under eaves.
This depends on the load. As a realistic example, a 10kWh battery could run ten 100-watt light bulbs for 12 hours without recharging.
The number varies based on home size, energy consumption history, and personal goals (like which devices to run during an outage). For most systems, 2 or 3 batteries are installed. A detailed discussion of your needs is recommended for an accurate assessment.
Yes, it is possible, but it requires careful planning and significant investment. A true off-grid system needs a large enough solar array and sufficient battery storage to sustain your lifestyle. Cost and having an alternative energy source for when solar charging isn't possible are key considerations.
No. CMX Battery focuses on building long-term relationships with business partners like battery distributors, solar equipment dealers, and installation contractors worldwide, not direct sales to end consumers.
