## Description

**LONG MSK Series batteries**: carbon-enhanced AGM (Smart-Carbon) for frequent cyclic use — daily solar, intensive RV. 100-200 Ah.
Carbon in the negative plate delays sulphation and tolerates partial-state-of-charge (PSoC) without damage — 1,500+ effective cycles at 50% DoD.

## LONG MSK — Smart-Carbon AGM

Carbon additive in the negative plate works as a sulphation inhibitor: the battery tolerates long periods in PSoC without capacity loss. Useful in off-grid solar where you don't reach 100% in winter.
Code Ah Cycles 50% DoD Application
MSK100-12 100 1,500 Solar RV
MSK150-12 150 1,500 Family off-grid
MSK200-12 200 1,500 Big off-grid, boat

### Applications

- Off-grid solar accepting winter PSoC
- Intensive RV use
- Marine house bank with high daily loads
- Remote telecom without continuous connection

### **Better than LiFePO4 lithium?**

No — LiFePO4 gives more cycles and depth. But MSK costs 3-4× less, with 2× the cycles of standard AGM. Good cost/duration compromise.

### **Special charger?**

Standard AGM curve works. To extract all cycles, use a charger with PSoC profile and temperature compensation.
