Yilink LFP-ABS
12.8 V and 25.6 V lithium batteries — lead-acid replacement
The LFP-ABS series drops straight into an existing lead-acid housing: same formats, same M6 terminals, ABS case. It multiplies cycle life sevenfold and halves the weight.
- Voltages
- 12.8 / 25.6 V Voltages
- Capacities
- 50 – 200 Ah Capacities
- Cycle life
