Melasta has developed high performance Lithium Iron Phosphate (LiFePO4) and Nickel Zinc (Ni-Zn) batteries to provide the best quality with extreme discharge current flow. These are technological advantages of Melasta Starter Battery
1. 80% lighter than Lead-acid batteries.
2. Perfectly works in low temperature (-40) conditions.
3. Integrated Battery Management System (BMS) to monitor battery health.
4. Wide temperature range series -20oC to +60oC.
5. Perfect solution for lead-acid replacement batteries.
6. Low self-discharge rate.
7. Comply with International safety standards including UN38.3, and CE.
These are the performance graphs for the Nickel-Zinc (Ni-Zn) Battery Model 1.65V 2600mAh HP49C260 under these conditions. These cells used for this battery.
