48 volt battery configuration.
Decideding between 8 6 volts or 6 8 volts. Looks like there will be about 150 lbs weight difference. Is the extra lead of the 8 6 volt configuration worth the weight. How much run time would it add. Anyone looking into both options ?

Re: 48 volt battery configuration.
That's an interesting question. I have not done this myself but looking at the specs on the Trojan site we have the following:
6V T-105 225ah (20 hour figure) 62lbs = 1800ah @ 496lbs for 8 batteries T-125 240ah (20 hour figure) 66lbs = 1920ah @ 528lbs for 8 batteries T-145 260ah (20 hour figure) 72lbs = 2080ah @ 576lbs for 8 batteries 8V T-875 170ah (20 hour figure) 63lbs = 1020ah @ 378lbs for 6 batteries T-890 190ah (20 hour figure) 69lbs = 1140ah @ 414lbs for 6 batteries Ranger 204ah (20 hour figure) 76lbs = 1224ah @ 456lbs for 6 batteries Just based on these figures it would seem that 8x6v batteries are worthwhile despite the increased weight but, of course, they also take up more room and are substantially more expensive (8x6v are a lot more than 6x8v). It's an interesting comparison all the same. |

Of course it will not be like that!!! The batteries are in series so the ah stay the same and the voltage is cumulative. The pack will be 48V and the ah of one battery. So: 6V T-105 225ah (20 hour figure) 62lbs = 225ah @ 496lbs for 8 batteries T-125 240ah (20 hour figure) 66lbs = 240ah @ 528lbs for 8 batteries T-145 260ah (20 hour figure) 72lbs = 260ah @ 576lbs for 8 batteries 8V T-875 170ah (20 hour figure) 63lbs = 170ah @ 378lbs for 6 batteries T-890 190ah (20 hour figure) 69lbs = 190ah @ 414lbs for 6 batteries Ranger 204ah (20 hour figure) 76lbs = 204ah @ 456lbs for 6 batteries There is an increase in the ah for using 6v batteries but it is not enough to account for the extra weight and expense, not to mention finding the space for two extra batteries. Sorry for that previous post being such an abomination. |
