Two battery banks have been tested and are described here namely a deep cycle lead acid battery and a lithium battery (LFP) (LiFePO4).
Lead Acid Battery:
The battery bank consists of 10 Trojan batteries of type T1275.
The specification sheet for these batteries is available here: http://www.trojanbattery.com/pdf/datasheets/T1275_Trojan_Data_Sheets.pdf
The batteries have all been installed in the back of the vehicle behind the Cab. A battery Box has been built around the battery bank and a fan has been provided to extract Hydrogen during charging.
The battery bank consists of 40 LFP cells from Synopoly, Type SP-LFP-100AHB. Cells can be obtained from LBSA (https://lithiumbatteriessa.co.za/collections/frontpage/products/3-2v-120ah-lithium-ion-phosphate-battery-cell?variant=31982240825434).
The batteries have all been installed in the back of the vehicle behind the Cab by means of a metal frame.
