    BMS 5A Charger

    Quick question - embarrassed to even ask. If a battery pack has a 5A charge BMS, can I use a basic 2A charger? I don't like the idea of using a bigger charger you see as I read that fast charging can be dangerous. Thanks

    Senquan, have you made any progress with this?

    Pendleton eSomerby Controller Upgrade

    @Bikes4two how do you find the gearing on the Pendleton? I converted one to electric and I find that I'm out pedalling the gears very quickly. That is, I seem to pedal faster than the bike expects and so above a certain speed (say 12 mph approx) I'm pedalling but no torque, no gain. I get that...

    21700 10 Ah Battery Build: Peer Review

    I've been testing the battery on my commute. Range and reliability are my two main needs. Running through the miles so far with over 30 miles and half battery remaining. This is on 4 as standard and 5 on hills. I'm one who doesn't see the point in using pedal power if you've got a battery. So I...

    21700 10 Ah Battery Build: Peer Review

    These are LG M50LT 21700 with 5Ah and max discharge 10A I've attempted the copper/ nickel plated sandwich and will need a more expensive welder. Also, have read through the forum thread (thanks) and it seems that, even with a KWeld, many are having hit and miss with the strength of the weld...

    Thanks. Had a read. A lot to get my head around there. In your 21700 build - are you completing a single weld of both copper and NP combined? Or a weld of copper plus a weld of NP? - you've cut copper squares rather than strips/H? All fine? Thank you again

    This is great feedback. Thank you. I'm going to look more into the copper and nickel thing. Any reason not to use pure nickel (rather than coated), other than price? Many thanks

    21700 battery build

    Ah, yes I see now. Final question if I may. On/off switch. Do you rely on the lcd for power on/off? What would safety protocol say? Thank you for your patient insight.

    21700 battery build

    So I sourced a Daly as I wanted the waterproofing and now realise it is common port. Regarding the charge, what connection are you using to go from XT60 to a common charger? I am using XT90 but can only find this with a male charging connector. I would have thought that it would need to be a...

    Great instructables. Where is the charging cable? Would you not have a charging cable from the BMS? Thanks

    Neat looking controller at TBK.

    How might this be secured within a frame? I can see where it may sit but how to stop it rattling? Presume an exit hole would be needed to be engineered?
