Was thinking that until Li-ions get lower in cost, there needs to be middle ground. Something between SLA and Li-ion that is lighter and lower cost than SLA...
Hello Joshua, The prices for NiZn at electricabenergy.com seem pretty reasonable so far. I looked into buying Evercels from Evercel and SEC Battery and came...
What I meant was there needs to be an alternative to Li-ions. Something in between SLA and Li-ion. A Batt that is better than one and not as good as the...
