Building my first Lipo pack for a BBS02 750W trail machine. Currently lugging my 22 lb LiFe 20Ah battery in a backpack which gives me 3+ hrs of riding but I want to build something much smaller and mount it to the frame of the bike. I'm very interested in the Multistar

Trying to decide whether to build a 13SP1 (3x3 & 1x4) or 14SP1 (3x2 & 2x4) pack. I don't want to use a BMS and would rather have the low voltage cutout on the BBS02 controller save my pack. 12S seems like the voltage levels would be too low to get the most power out of the pack before the Low voltage cuts in. I think the low voltage setting is 41v from the factory, but I don't know because I haven't programmed mine. This is the only screenshot I can find for the BBS02 settings

Also interested in opinions on the best inexpensive charger I can get that will balance charge all 4 packs at once (I don't want to bulk charge)
I'm thinking of getting this one

You guys are the experts. Looking for the safest configuration (not killing batteries from overdraining) to get without having to reprogram the BBS02 with different lvc or having to use a BMS.
