Product Highlights
Fast Charging
LiFePO4 batteries can recharge much faster than conventional sealed lead-acid batteries, giving you access to reliable power quicker.
Minimal Self-discharge
Lithium iron phosphate batteries have a low self-discharge rate of about 3% a month.
Flexible Connection
12V LiFePO4 batteries support series and parallel. Up to 4 batteries in series or up to 2 in parallel for 12V, 24V, 36V and 48V systems.
Easy Installation
Lithium batteries are designed as a drop-in replacement for lead-acid batteries. The dimensions of the lithium batteries are the same as the dimensions of lead-acid batteries, but 60% lighter than sealed lead-acid batteries.
High Discharge Rate
LiFePO4 batteries can be discharged to 100% and can also be discharged at a high rate of up to 1C for most models while maintaining a high energy capacity. Refer to the datasheets for specific specs.
Intelligent BMS
Li-ion batteries come with a built-in smart battery management system protects against low temperature, high temperature, over-discharge, over-recharge and short-circuits.
Long Cycle Life
Lithium Ion battery feature more than 2500 cycles at a depth of discharge of 100%, 3,500 cycles at 80% and 5,500 cycles at 50%. The recommended DOD is 80%.
Term of trade
1. Payment: 100% T/T in advance for sample order; 30% advance payment by T/T, 70% balance should be paid off before shipping for bulk order.
2. EXW, FOB and CIF all are available.
3. Production lead time:30-35 days based on the order quantity.
4. Discounts are offered based on large quantities.
Q&A
Questiion1: Is this lithium ion battery safe compare with lead acid battery?
Answer: Lithium battery is much safer as it has BMS to provent battery from over charging, over discharging, short circuit, high temperature etc.
Question 2: Can I replace the lead acid battery directly by lithium battery?
Answer: Yes, the lithium battery can be drop-in and plug-play replacement of original lead acid batteries.
Question 3: Why does it seem your price little higher than other factories?
Answer: We always supply High-Quality products & High-Stand service to our clients.
Question 4: Do you have any MOQ limition?
Answer: Actually not, we support sample order for testing and qualilty checking, welcome for inquiry.
Question 5:How you shipping the goods and how long it will take?
Answer: Normally by sea. Shipping time depends on destination port. But we can also make shipment by UPS and FedEx for trial order.
