Battery meter options for RoyPow 51V105AH pack??
I just recently installed a RoyPow 51V105AH pack in my dad's Precedent. I was wondering if there are any battery meter options that would connect directly to the pack where the original meter attaches. If not, are there any other good options? Also, is a Lester Summit II charger compatible with that pack, and if so what charge profile needs to be used?

Yes, STOCK battery meter that came with the pack. Yes, Lester Summit II charger. I was assured that the charger had a lithium profile loaded. I was hoping there was a battery gauge that communicated with the pack Battery Management System via the provided jack on the pack to give me more info on the battery. Also hoping to confirm the proper charge profile with the Lester "Charger Connect" app on my phone. I have not connected to the charger yet to see what profile is loaded, wanted to know what the profile should be in advance.

As far as the charger, I'm not familiar with the Lester charger other than they've been around quite a while and are generally used for FLA type batteries. Maybe some of them are programmable, not sure. RoyPow supplies the correct charger (and it is not a Lester), but if you didn't get one somehow, you need to make sure the profile that whatever charger you use has is specifically intended for a 16S LifePo4 battery pack. A charger used for FLA batteries is not the correct charger, regardless of what someone may have told you. It is possible that it will "work" to add charge to a depleted battery, but it won't charge it as it was intended. IIRC, some of those FLA chargers take voltage up to 58-60v or so in the periodic "boil" stage intended to stir up the electrolyte, and that will not go over well with your expensive 16s LifePo4 chemistry battery and associated BMS which does not need or want to see 60v. |

Re: Battery meter options for RoyPow 51V105AH pack??
Yes the battery meter is the included RoyPow unit, and I do feel it is likely a good meter. I just am wondering if there is any alternative that gives much more information such as individual cell voltages and temps, etc. The Lester charger I was given with the pack purchase. I was advised that it had the correct Lithium charge profile loaded. I should be able to connect to it with the app tonight and try to verify that. I was hoping that someone could supply the details of that profile for me to confirm. I did google it and found some information about that, but do not have it in front of me right now.

Since charger didn't come from Roypow, I would consult with them directly to make certain it's settings are correct. Still wonder why yours didn't come with the Roypow supplied charger?

Lester does have a lithium profile, 22226?
I think it charges to 3.5 a cell 56v at 13.5 amps |

Re: Battery meter options for RoyPow 51V105AH pack??
I found the instructions for changing/checking the charge profile on the Lester website under technical bulletins. Profile 22226 for 51.3 volt lithium applications. I will post back what I find once I check/change it.
