Re: Large lead acid forklift battery self discharging

Just add support legs that extend forward then you need zero counter balance like the walk behind lifts... Otherwise lift less or add some weight, concrete as suggested above would be most cost effective and coming close to the weight. Most battery's are 2k-3500lbs in those lifts (its stamped on the...

Re: looking for 12s SENSORED esc/controller options

bigger outrunner (8057) just considering options for better start up power, other wise the edge160 works.
phaserunner looks interesting but lower amps definitely a possibly just to try the sensored performance out.

Re: Advantage of high cadence?

Can anyone explain to me the advantage of spinning the pedals at a high cadence? Numbers have been mentioned as high as 120rpm. There are two reasons I ask. First, any text on bio-mechanics tells us that muscles are strongest when they're stationary and get weaker as he speed of contraction increas...

battery options for motorcycle 40kw 400a 24s?

looking for some options/opinions on a battery for use in a future motorcycle project. peak power should be around 40kw assuming 24s(100v) 400a. obviously weight/space is somewhat critical, don't have a capacity in mind but aiming for 5kwh roughly (50mile range?). have been looking at various ev bat...

Re: Meanwell LSR-350-36 charger question

most of the power supply's (unless they are c.c) will do that. they think its a dead short and will go in to fault or protection mode. "Protection type : Hiccup mode, recovers automatically after fault condition is removed" you can use a current limiting board inline with the power supply to solve t...

By chance, has anyone found a decent off-the-shelf current/voltage display rated for 60V and ~ 6A? I think it would be nice to add one to the Meanwell supply in line with the charge output.
most watt meters do 0-60v and 0-150a and are only about 10$.. and show ah charged ect.
