A man that brokered electronic components for a decade that doesn't trust electronics. That says volumes.
Well look at your household electronics for example... especially laptops I receive recall notices for the battery in mine at least every 6 months for a laptop I tossed over a year ago and anyone who has an HP or COMPAQ laptop Im sure has received these same notices as well and this is a Li-Ion battery that overheats and catches fire... so we know that Li-Ion are combustible should they fail and to depend on a single IC to prevent that is absurd especially when that IC is constantly under pressure from not only the spring but could be easily shorted should you over tighten your GG crushing the IC rendering it useless... for me the IC protection is nothing more than a false sense of security for a dangerous battery to be anywhere near your face.... so again as far as Im concerned there is no other battery acceptable for use in PV's other than the LiMN safe technology batteries...
