I bought these ages ago to make a charger with but I've had too much to do.... one broken bmsbattery.com charger later and I've pushed these up to the front of the queue
7 x 12v 41amp dell server PSUs
1 x 5v 60amp meanwell
(for 24s)
plan is to isolate them all, then hook them all up in series and use the meanwell for voltage adjustment and current limiting
will need to mount voltage and current displays so I know what's going on, by the look of it I should be able to mount them into the top or end of the meanwell case, need to take it apart to check for clearance first
only running a 10ah pack right now, but I've got two new box frames being laser cut and cnc folded next week, once they're built up I'll be putting 50ah on each bike
(might be split into 2 packs, will have to see how will it fits/what access is like)
once I get this up and running.... I'll get another 5v meanwell and connect it in series to the server PSUs too, so I can charge 2 bikes independently but at the same time (with 1 meanwell each) I'd have got the 2nd meanwell straight away, but I wasn't planning on 2 bikes when I bought all this months ago
running a BMS on each bike, end of charge might be a bit slow, but I normally charge overnight anyway - I might stick fast/slow charge switches on the meanwells to switch between say 5amps and 18amps charge - I charge overnight most of the time but sometimes need to charge faster
wish me luck
