Are these batteries any good ?

gday gemini, you could use those batteries, im not sure of anyone who has used them before though. however, if your willing to wait for the next lithium bulk buy, you could get lithium at the same price as those AGM lead acids. im not sure a magna would make such a god donor vehicle. The biggest pro...

72 volt motor choice?

gday Bruce, LiFePO4 batteries are alot cheaper than US$2AH. in the last australian buy, we got the price done to $1.62AUD/AH delivered.(the price we paid was $1.10US/AH, the rest was shipping and duties) As far as adding batteries later, you shouldn't mix new and old batteries, so to upgrade you wou...

hi Pillip, most alternators deliver charge at about 700rpm or more. All do above 1200rpm. Please elaborate on your ideas for utilising the abundant power sources? LED lighting is a good way to go. Did you know an LED globe lasts for 10years if light continuously 24/7? i cnat wait till their cost com...

72 volt motor choice?

Gday Bruce, im not sure 115AH of floodeds at 72v will give you the range your looking for. If you are using the Trojan 27TMH batteries, at the 75A rate (only 5.2kw@72v), their capacity is only 63AH. at max 80% DOD, this reduces it to 51AH. this is only 3.6kwh. At 0.2kwh/100km this will only give you...

hmm, i wonder if the reva batteries are the sealed or the flooded tubulars? I didnt realise you could buy sealed 2v tubulars under 200AH. one of the reasons i hated lead batteries so much was because you couldnt balance at the cell level. It seems i was wrong. anyways tubular lead acids can be relia...

Tubular Batteries

No Tubular lead acid batteries are 2V single cell flooded lead acid batteries. They arent particularly power or energy dense, but boyo do they last a long time. Theyre the batteries that tend to be used in electric fork lifts. The driving range is a little optomistic (80 km will take you too 100% DO...

Hi fbear, if your campervan has a modern (1990s or newer) engine, doing a serial hybrid conversion will increase your fuel usage. Theres too many losses between the mechanical output of the petrol motor and the wheels. For a series hybrid camper van, you will need more like a motor bike engine. what...

you could look into reverse cycle airconditioning?
not sure how to achieve this in a car though, but it may not eat into your range quite as much.

gday BCB, Are the batteries for auxilaries or for traction? If its for auxilaries, using the generator is very doable, though you may find it better to just use the generator directly when you dont have access to power, rather than using it to charge the batteries, and using the batteries to power t...

going hybrid is a challenge indeed, with limited returns. you will need to start out with a vehicle that is either already a hybrid, or has a significant payload capacity, as the only drivetrain heavier than a pure electric is a hybrid one. what type of car are you considering? re the jet engine sta...

yes, its odd that we havent seen any balancing function of any sort on any of the factory EV's i have seen. none of the ev's discussed on the visforvoltage forums have any. The same is true of AH counters, none of the scooters use an AH counter as a fuel guage, they all use voltmeters. but we're a m...

feel free to correct me, but every time i hear of an "air car" scam comes to mind. 4 or 5 years ago, homepower did a piece on storing energy in the form of compressed air. they calculated that a 1.5m tall 50cm wide cylinder raised to 3000PSI stored 0.5kwh. The energy density of compressed air is eve...

you could use 2x36v20A chargers from kipoint on ebay.
just connect a string on 12 to each charger.
itll cost you about $500 delivered. just a thought

yes, hydrogen has many properties that arent friendly towards engines. Its less stable (much much lower octane, around 40) so its far more prone to predetonation...its on par with putting diesel in your fuel tank.
