i see it now tx

hi i used to have a charger i could move a button to select gel or lead . i dont have it anymore. the one i have is lighter and smaller see pic but it does not seem specific to gel batteries. it has no button to switch or select the type of battery to be charged yes i can charge with it but a...

Hi ok i understand the situation better now. on top of replacing the cell i will change the link from them to the other neigboring cells. i appreciate that you confirme that this way of doing is possible and can still be tested because unsoldering all cells takes a while . ill check what my...

sony vtc4 are 2.5 rated. the 4 cell at 0 will be discarted. the battery never served. Are you saying that even though the 11 x2 cells are showing 3.5 volt they have to be tested? i feel if they were faulty the voltage would show 3.5 . i dont get why the 11x2 cells could be a problem can...

is the third post you talk about Discharging to 0% will very quickly murder even a top quality pack, every LI chemistry with LTO as the sole exception. Certainly if you define 0% as dead flat. The **average** DoD% over the battery's life has a huge impact on cycle lifespan, a much stronger...

hi before building the battery i did select the cell that had voltages not decreasing much over time. they are vtc4 and vtc3 cell sony from dr bass so i feel they are good quality cells. what makes you beleive that the 11 parellel group that show 3.5 v are bad cells?

I just want to make something that makes sense. if the 11 out of 13 parallel group are showing exactly 3.5 my reasonning is that those 11x2 22 cells are in good shape. is this reasoning correct? if so they can be left untouched now for the 2 parallel groups showing 0 volt is there a way for...

it is a test battery mostly to test my new motor and how it goes up the hills. changing the 4 cells would be less than one hour. it know it would be a tiny capacity but it is a test to also tels test my setup on bike and wiring. ... so since i already have 4 spare cell do you think replacing...

well since all the rest of the groups show 3.5v if i replace the 4 cells, would that solve the problem? why do you say that there seems to be an inherent problem (like a leak) with my battery? if i redo the soldering around those cells does that solve the problem you see (that i still dont...

i feel confused about what you are directing me at since you wrote couples of messages can you paste it ?

hi the link when i click it brings me back to how to interpret this data? something is not working is this what youre talking about?

hi what do you mean by objective testinG? does taking the voltage of parallel group is sufficient testing? they all show 3.5 apart from 2 parallele group where i can only read 0 readings could you rephrase this , im still learning english tx just replacing the worst cells is only going to...

here is the post where i need help tx https://endless-sphere.com/forums/viewtopic.php?f=14&t=113146&p=1673409#p1673409

hi what do i have to do . do i need to replace the 4 cells ?

presume this first time used this controller, is it new yes? do you have a throttle thumb yes? if so how many wires? 3These are the only wire wich color dont mach apart from the break that the color dont mach neigther. should be 3 , if not then white probably goes there, not sure of specs on...
