So, I’ve graduated from my 2 x Zippy 4s1p 8000 mAh (8s1p) Lipos. I’ve ordered my Basen 26650’s from Liion Wholesales. I’ve ordered enough to make an 8s4p pack.
The Zippy’s gave me plenty of torque and speed (~27 mph top speed) but the distance wasn’t far enough (~12 miles) and I eventually started getting a puffy pack and my distance on full charge started dropping. An 8s setup seems fine for me. Yes, I understand I should get a pretty insane distance on the Basen 8s4p pack.
I have a no-longer-called-a-VESC controller dialed in for 8s voltages on the Lipos and have a few questions.
I’ve read just too much on voltage limits and am second guessing myself. These batteries are the 60A 4500 mAh Flattop. I know they are more like 30A continuous. But what are good cutoff values for them in volts for the controller? Lipo Battery cutoff is set to start at 3.6V and battery cutoff end at 3.2 V? For this battery configuration???
I also bought these to last. I’ve read the pros/cons on using a BMS. It seems that BesTech is the one to use if I do. Which one? Thoughts?
I was going to solder BMS leads either way. This would allow me to check each battery individually and charge/balance if needed. I’d really rather have it set for plug-n-play on charging if possible.
I also purchased a coulometer to keep an eye on the actual mAh and voltage so I don’t abuse things too much
So can you provide any insights, tips, or guru direction?
