About the publication

Three different batteries of different chemistries and different design have been purchased and tested for use with efficient electric cooking appliances. These are:
1. Lithium iron phosphate (LiFePO4, also known as LFP).
2. Valve-Regulated Lead Acid (VRLA). These units were manufactured by Yuasa.
3. Lead-Carbon, which is like lead-acid but with reported higher tolerance to deep cycling.
These units were manufactured by Leoch.

In the context of the MECS project, the batteries are required to operate cooking appliances. In offgrid applications they are needed to store solar PV electricity. In weak-grid or mini-grid applications,
batteries are needed to store electricity for later use, when grid electricity is more expensive, insufficiently powerful, or unavailable.
