    What is the range you get on that pack? how come you need such a large pack as most commercial units max out at 500Wh and the most sold Bosch pack is the 300Wh version.

    We specialize in fast charging and you can fast charge cells with very minimal side effects as long as you are able to monitor certain variables then you are OK, our system basically lets the cells decide their charge rate instead of the charger. we see 1,500-2000 cycles on the cells we use.

    Hi Ttxela, What is the battery pack and motor you are using? I know that 15 minute charging will not appeal to everyone, we are either looking for someone who wants a lighter pack, more discreet and secure pack or just likes the idea of being able to recharge in time to go grab a drink :-) Thanks

    For the 150Wh version you require a 600W charger at 10.6 amps. For the 300Wh verison you require a 1200W charger at 22 amps. We have our own charging and connector tech so we are creating our own chargers that are able to handle these amp outputs. Thanks *edit* the watt ratings are outputs...

    We have been focusing on the power density of our packs which means that not only can we charge in 15 minutes but we are easily able to output 60 amp continuous. We have also decided to use the 48v drive system as the higher voltage means less amps (higher efficiency). This also means there will...

    I think our main target audience are people who do around the 30 mile mark as a commuter, so we think the battery pack for a 300Wh unit would be around 3kg, the reason we are also making a 150Wh version is so we can have ultra light units that can do 10-15 mile per charge that would be more...

    One of the options we are suggesting is the same 300Wh pack will be 30% heavier than the equivalent 300Wh on the market now; so do you prefer a lower Wh pack for the same weight or a heavier but equal power pack?

    Help us build a better Ebike battery

    Hi all, I am new to the ebike scene, but my company has started to develop an Ebike battery that can be fully charged in under 15 minutes and will be charged safer than traditional charging (our IP). We are looking to have this tech mainly sold to bike hire schemes (boris bikes) that will be...
