Re: Help Please on 10s bms install on 10s2p pack

Success, The above youtube video shows at 29 seconds the proper connections for the nickel strips as four square configurations plus a pos and a neg parallel connection. The bottom would have only 5 square configurations. Problem solved.

Re: 10s bms install on 10s2p pack

This video by Mike from Vruzend shows my dilemma.(https://www.youtube.com/watch?v=m4DGDkwFr54). He demonstrates how to wire a bms to a 50 cell pack in a 10s5p configuration. At 0.29 into the video he shows the top of the pack with the configuration of the nickle strips . Unfortunately you do not get...

Re: 10s bms install on 10s2p pack

Hi flat tire, thanks for responding. I have 2 x 10s paralleled into a single 10s2p pack. I have only 1 11 wire bms. I have seen videos that use 1 bms . I am not sure what the balancing capability of my bms is but my main concern is safely charging so no cell goes over 4.20. How is this done? Wouldn'...

Re: 10s bms install on 10s2p pack

Think about it. Trying to install a 10 cell bms on a 20 cell pack. If you simply install a bms then your only protecting 10 cells . You could install an additional bms but this would be cumbersome when you want to charge the pack. Most videos I have seen use 1 bms and interconnect the cells so you c...

I have this post in the battery section .Almost 30 views there but 0responses. Sure glad I posted here also anticipating lack of response there. The idea is to bms protect a 20 cell battery pack with 10s bms. One could I suppose install 2. 10s bms and individually charge via each bms although cumber...

Re: Help Please on 10s bms install on 10s2p pack

Sure it's a 4ah baby pack but easily upgradable anytime once I figure out how to link the cells to use one 10s bms.
I have seen many videos assembling bms protected battery packs but they all suffer from inadequately showing how the cells are interconnected.

Yet you can`t register an eBike in NYC even if you want to. We e-bikers bring attention to how laws...
