14.4V 33.5Ah (482.4Wh) NMC Lithium-Ion Battery — SLA/Lead-Acid Replacement, F2 Terminal
$55.00
Drop-in NMC lithium-ion replacement for 12V sealed lead-acid (SLA) batteries. Delivers 14.4V nominal voltage and 33.5Ah (482.4Wh) capacity in the same case footprint as standard SLA batteries, with F2 spade terminals for direct compatibility — no rewiring required. Lighter weight, higher energy density, and built-in BMS protection.
Full Description
The 14.4V 33.5Ah NMC lithium-ion battery is a direct drop-in replacement for standard 12V sealed lead-acid (SLA/AGM) batteries, housed in the same industry-standard case dimensions with F2 (6.3mm) spade terminals for plug-and-play compatibility. This lead-acid-to-lithium conversion battery is designed for users upgrading UPS systems, e-scooters, alarm/security panels, emergency lighting, and other equipment originally built around SLA batteries — without needing to modify wiring or mounting.
Built with premium NMC (ternary lithium / nickel-cobalt-manganese) cells in a 4S configuration, this pack delivers stable 14.4V output with excellent energy density, offering strong capacity in the same footprint as a lead-acid unit. Compared to an equivalent SLA battery, it offers significantly lower weight and stable voltage output throughout the discharge curve. An integrated BMS protects against overcharge, over-discharge, overcurrent, and short-circuit conditions.
Key Features
- 14.4V nominal voltage, 33.5Ah / 482.4Wh capacity
- NMC (ternary lithium) cells, 4S configuration
- Same case footprint as standard 12V SLA batteries — true drop-in replacement
- F2 spade terminals (6.3mm) — compatible with existing SLA wiring/connectors
- High energy density — significantly lighter than equivalent SLA battery
- Charge cutoff 16.8V / discharge cutoff 12.0V — standard NMC charging profile
- Built-in BMS: overcharge / over-discharge / overcurrent / short-circuit protection
- Maintenance-free, no acid leakage risk
- Wide operating temperature range
Applications
UPS/backup power systems, e-scooters and e-bikes (SLA-based models), solar lighting, security/alarm systems, emergency lighting, golf carts, and other applications currently using 12V SLA batteries seeking a lithium upgrade.
