DC-DC converters experience

Wanted to offer feedback on my DC DC converter experience with my project. 1. i bought an ebay spec 144v-12v converter from a chinese supplier on ebay. the unit was very ordinary build quality. ie they claimed an IP5x rating or similar but when it turned up, the backing cover was loose and it was no...

Battery pack voltage advice for EV datsun 1200

Solar panels - cool! And at 200W, would only take 34 hours to charge! I wonder if you could rig it so that you could tilt the hard cover towards the sun. Or it might not make much difference that far north? NQLD means that you don't have to worry about the battery temperatures, so your battery boxe...

Congratulations on another EV on the road! Looks nice and tidy under that bonnet. Any more details/pics? I'd like to see how the rest of the batteries are mounted. Whenever I see someone using clear plastic I can't help but wonder how much cleaning they'll have to do... Here is the zener balancing ...

Battery pack voltage advice for EV datsun 1200

My Optima D34 batteries where charged to 14.5V and then charger went to float mode. After switching off the charger the Voltage would drop down to 12.9-13.2V. I think 0% SOC would be 10.5V? The Optimas only lasted 9000km in my car and that was with shallow discharges to 70-60% SOC. You should consi...

This guy recorded a huge amount of info. about his EV yellowtops. It appears the charger(s) were at fault for some early failures. http://www.oocities.org/s_medhus/optima.htm the 2 links you posted have different values in the SOC table. infact i think i did find both of these websites some time ag...

Hi all,

Thanks for the help and explanations so far.

Battery pack voltage advice for EV datsun 1200

I'd be sticking with the 144V. This is 'rated', the same way the optimas are '12V'. They go higher when charging, and the '144V' rating usually allows for this. If you want 3 years out of a set of Optimas (which can't be balanced with a gassing charge, since they're AGM) then you also need a BMS. T...

i still think the lithium is a pretty big investment and carries reasonable risk...
