Hello everybody
We have 1.8 hp dc motor that is Voltage max dc =180v.
we have 10 battries [(12 Volt/12 Amp Hour) Sealed Lead Acid Battery ]

we are using a buck-boost converter from 0 - 150 volt
the vehcile is about 40 kg or more say 45 kg without battries

with battries + driver +some equipment is about 150 kg

we have installed the motor in the vehicle & connected
we test it in the lab with a variable dc source we saw that:
with 150 kg on it it moves by 70 volt dc & 25 amps


we need your advice on the converter & dc motor

if we boost the voltage to 150v will they withstand or break ?
should we just keep it a buck - converter from 0 -120v ?

we need your advice for the way to build up a buck - boost converter or a buck converter circuit and which is better for >>>voltage in and voltage out and duty ratio input current outpout currnet and the ripples ? for designing this circuit

what is the best idea you have for this project ?

if you have any good idea pleez post it here
thank you guys
i will be waitin
