Trying to outguess battery cells prone to hysteria and paranoia without individual cell monitoring and individual charging is just plain nuts.
I have been playing with a different chemistry lithium battery (3 x 3.7 volts in series) and in order to successfully charge it, I have to gradually increase voltage to 11.2 volts while monitoring individual cell temperature -- and that still isn't the correct way to do it --
It takes programmed software management for both charging and discharging management. An A to D software program and individual cell managers. Automobiles have such sophistication but an aftermarket battery?
Until I see modules with independent individual cell monitoring and management capabilities I intend to keep my distance.
