Just got one of these this week. http://www.7dayshop.com/products/7dayshop-waterproof-rechargeable-intelligent-rear-indicator-bike-light-WH2-CM-002 . Rechargeable, auto shuts off after 3 minutes of the bike standing still, comes on automatically at night and has indicators as well! Pretty good...

This would do the same, just have it configured for 10s 36v (42v) https://bmsbattery.com/ebike-charger-ev-charger/24-alloy-shell-120w-lifepo4-li-ion-lead-acid-battery-ebike-charger-ecitypower-charger.html

Just an update on how the cells are performing. Very well indeed. I made a 6p10s pack for my A2B Metro and very little sag, great power delivery, nothing to complain about. Build was a PITA though, serves me right for wanting to recreate the original rear pack. Frame pack to rebuild next!!

manufacturer just got back to me to say it's supposed to be like that.

Thats how the original pack looks. I'm rebuilding by soldering to the tabs of my new cells in the same configuration 10s 6p. I'm using thick 32A solid copper wire to connect the cells together.

I designed it myself as there's no pedal assist on the gen 1 or any kind of dashboard. Next job is to move from simple pedal assist to building an actual torque sensor. i.e. if you're having to push harder the throttle will ramp up to meet you so to speak. Still working out the how to detect though!

Config is actually 6p 10s, I'm just rebuilding a pack for mine.

I'm currently building a new rear pack from cells from Tumich on here. See the for sale section. Samsung 29e in a 6p10s config. I'll let you know how I get on. Could do with an empty rear case if anyone's got one!,

Emailed them and will try it at arms length soon!!

Listing for the 40A version from the same seller shows the missing part as well! coincidence ...

If you look below the gap about an inch, there's the transistor! not sure of this design, but checking all the other one they sell, they all have a missing (or relocated) cell one transistor.

Is it one like this? http://grifftek.com/grifftek/Other_Fun_Projects_and_Hobbies/a2b_battery_packs/

Just received my 30A 10S BMS and noticed something seems to be missing. Is it supposed to be like this or is it faulty?

That pack looks great, good job there! Where did you get your nickel strip from, I'm having trouble getting some in the uk. Im wanting the 10mm stuff.

Already wrapped up in tape and in my metal bin full of sand. Did you notice I'd scored a real bargain on a charger recently? :)
