Gosh, I never thought I would type that into a subject line. Oh well.
We have this "car" here:
https://dempseymotorsports.com/mit-aztec-solar-car/
It currently has six lead-acid Odyssey Red Top batteries in it. They are very old, and I would like to upgrade / replace them with lithium-ion batteries. But I'm slightly confused and Google is not helping too much.
Each Red Top battery is rated at about 50 or amp-hours according to their data sheet page:

Here's a sample "replacement" kit I found while searching the interwebs:
https://batteryevo.com/product/72v-falcn-4x-kit/
Aztec has six red top batteries - 12V at 50-amp hours. Putting six together should result in 72V with 50-amp hours? Power is current times voltage, right? So, total power should be 72 * 50 = 3600, I believe the rating is watt-hours then?
So the kit above with the 108 Ah rating would be 72V * 108 = 7200 watt-hours.
Or, more specifically, if I were to replace the batteries with similar capacities, then I would probably only need this?
https://batteryevo.com/product/72v-falcon-2x-kit/
This kit is 54 Ah at 72 volts which would be 3,888 watt-hours. Each one is about the same weight as a lead-acid battery, but seems to be three times the capacity.
So, I guess I'm looking for some confirmation - the six red top batteries could fairly easily be replaced with this two-battery set here and would have the same capacity with a lot less hassle and 1/3 the weight? Yes / no?
Thx,
Wayne
