CHARGER
Get the best charger that you can reasonably afford. Statistically most battery incidents occur while charging.
Pila,
Xtar, and
Nitecore are the most recommended brands.
BATTERIES
Sigelei recommends
30A CDR batteries for their 150watt mod.
30A CDR is the highest amp battery available. Any battery labeled 35A, 38A, 40A, etc is labeled with the "pulse" not the continuous. From
@Baditude's blog:
Purple Efest Batteries not as Advertised
Here are some options:
1. Orbtronic SX30 2100mah 30A
2. Sony VTC4 2100mah 30A (there are no
new stock authentic VTC5's out there that I know of)
3. Xtar 2100mah 30A (re-wrapped Sony VTC4)
BATTERIES - WHERE TO BUY
Only buy batteries from a reputable supplier (not ebay or Amazon) as there are many counterfeit batteries being sold. Here are several reputable battery suppliers in the US.
