The RAV-4 used NIMH batteries developed by toyota. It weighs more than the chevy volt, is not aerodynamic, and gets more than 100 miles per charge on the equivalent of 2/3 a gallon of gas.
On their website, I only see a 24V, 9AH battery available. NiMH are extremely difficult to charge in parallel and the highest voltage EV powertrains on the market are up to about 650V. DC systems usually don't exceed 360V, but there are some 650V siemens AC setups. So 27 of those batteries in series is 648V and 9 AH, or 7.642 kWh nominal. Will give most EVs a 30 mile range. More practical just to use a larger AGM pack.
Now, if Nilar has some 60 AH modules available or larger in size, let me know! Those would do the trick for a viable 100+ mile range conversion. NiMH are going to be impossible for a hobbyist to parallel; the best electrical engineers have difficulty doing this and preventing one string from going into thermal runaway due to NiMH's charging profile, so parallel NiMH setups aren't viable. And I screwed up that last calculation. I tend to do things mentally.
