STF 12.8V 90Ah LiFePO4 Battery
The STF 12.8V 90Ah LiFePO4 is lithium done properly — a 15S10P pack of CBAK 32140 cells rated for 2500 cycles, protected by an integrated BMS, and warranted for 3 years. The long-life replacement for lead-acid duty.

Where this battery belongs
Solar storage, inverter backup, equipment power and mobility applications running on 12V-class batteries — anywhere a lead-acid 12V battery works today, this LiFePO4 pack works longer and lighter. BMS handles cell balancing and protection automatically.

Cycle count is the real price tag
A lead-acid battery delivering 400–500 cycles against this pack's 2500 means the LiFePO4 outlives four or five lead-acid replacements — the higher purchase price amortises into the cheapest energy per cycle you can buy. Add usable depth-of-discharge and the gap widens further.
Named cells, not mystery lithium
This pack declares its internals — CBAK 32140 cells in a 15S10P arrangement under a proper BMS — which is exactly what to demand from lithium suppliers. Packs that won't name their cells are hiding the answer to how long they'll last.
Ordering, applications and bulk supply
Batteries are application items — the right chemistry, voltage and BMS depend on what the battery will run. Every enquiry starts with your application (inverter, UPS, solar, machinery, devices) and we confirm the correct battery before quoting. Bulk and institutional orders ship on one GST invoice; custom LiFePO4 packs can be built to your voltage, capacity and connector specification.
