Re: Super capacitors anyone?
I received 20 supercaps for free from Maxwell some months ago. They still lay in my drawer, unused. :-( What I miss/need is a powerful buck/boost DC/DC converter! Without it, SCs have no use on an electric vehicle! Indeed, a SC can be discharge down to 0V, so you can use almost 100% of its energy......

Re: "UltraBattery" Lead-Acid Supercap Hybrid Battery Class
Are they available for purchase?
Where?
At which cost?
Would they perform better than lead-crystal batteries or TPPL (Tin Plates Pure Lead) batteries?

Direct lead battery replacement by LiFePO4
I read on datasheets of some 12v LiFePO4 packs that no more than 4 of them can be connected in series "due to internal circuitry limitations". Does anybody know why this happens? And why do not all of the 12v-lithium-packs manufacturer write this in the datasheet? Missing this info, how ca...

LiFePO4 cells & packs sold in Europe?
Which is your favourite European dealer for LiFePO4 cells, packs, BMSs and whatever? I only know EclipseBikes and LipoPower.

Re: Need to make an adapter for type 2 to caravan type 16A?
I need to pull just 0.5 kW from an european EVSE equipped with Mennekes outlet; any tip about where to find schematic of circuitry I must add to an empty 3d-printed mennekes VDE plug to enanle EVSE to provide current?

Mitsubishi, Peugeot and Citroen batteries
Do all i-Miev clones mount same batteries?
And which are original Mitsubishi batteries? Any full datasheet available? Life expectancy? At which C rate?

Re: discharge battery
If you have a 10ah cell its pointless having a 1ah bms or a 100ah bms. Some do measure current and so this matching of the cell to the BMS is important, some merely monitor voltage and so are less critical. BMS works on A, not Ah. The design sequence is: - chose the power of the motor (e.g. 2000W) ...

Re: discharge battery
hello !! i have several qustions about battery discharge: 1) if the battery is 5000mah and have a discharge rate of 3c then the corrent is 15 A, but what happen if the motor consumed only 10 A current ? Is the engine overheats ?, and how this affect the battery ? No, the motore "decide" h...
