🔥 Parameter Summary
1. Basic Performance
Model & Specifications:JCY-1215, Lithium Iron Phosphate (LiFePO4) cells.
Core Electrical Parameters:Nominal voltage 12.8V, rated capacity 15Ah, energy 192Wh.
Weight & Dimensions:: Approximately 1.6 kg (3.53 lbs), compact design (~151mm x 99mm x 95mm), highly portable.
2. Cycle Life & Warranty (Core Advantage)
Exceptional Cycle Life: Supports deep cycling, offering over 4,000 cycles at 100% Depth of Discharge (DOD). With partial cycles (e.g., 60% DOD), lifespan can reach 15,000 cycles, far exceeding lead-acid and some other lithium batteries.
Warranty Policy: Comes with a 2-year standard warranty, extendable to 3 years upon registration, demonstrating strong confidence in product reliability.
3. Charge/Discharge & Protection Performance
Charge/Discharge Currents:Standard charge/discharge currents are 3A/7.5A. Supports a maximum continuous discharge current of 15A, suitable for higher-power devices.
Voltage Protection Points:Discharge cut-off at 8.8V, over-discharge recovery at 10.8V, charge voltage at 14.4V, all precisely managed by the BMS.
Temperature Tolerance:Wide discharge temperature range of -20℃ ~ 60℃, suitable for harsh environments. Charging must be above 0°C.
BMS Features:Integrated 15A BMS provides protections against overcharge, over-discharge, overcurrent, and short circuits. Includes LTCP function (Long Time Connection Protection) to prevent damage from prolonged idle periods.
4. Construction & Expandability
Protection & Material:Housing made of flame-retardant ABS plastic with a high protection rating of IP65 (dust-tight and protected against water jets), ensuring safety for outdoor use.
Expandability:Supports up to 4 series 4 parallel (4S4P) expansion. For example, a 4 parallel 2 series (4P2S) configuration yields a 24V/25.6V 60Ah (~1536Wh) battery pack, meeting higher voltage and energy needs.
5. Recommended Charge Controller Settings (Important Note)
Charging Settings:Constant Voltage/Bulk/Boost voltage should be set to 14.4V, Over Voltage Disconnect to 14.6V.
Discharge Settings:Low Voltage Disconnect should be set to 8.8V, Under Voltage Recovery to 10.8V. These settings match the battery's internal protection parameters, ensuring optimal safety and lifespan.
