FYI ... Copied from the Vamo Battery Thread
A group of people who know about batteries and safety contributed to the ECF guide on batteries:
From that guide there is this:
We now advise that Li-Mn or top-quality Li-FePo4 rechargeables are used in APVs, in preference to rechargeable Li-ions. We suggest the best option, in order, is:
1. AW IMR Li-Mn rechargeables.
2. AW Li-FePo4 rechargeables [Li-FePo4's MUST HAVE A SPECIAL CHARGER]. Note that these batteries are mostly 3 volt nominal so the system voltage will be lower than normal.
3. Good quality (such as AW or Pila) protected Li-ion rechargeables.
4. Branded protected Li-ions come next - such as xxxfire Li-ion rechargeables (for xxx insert Trust / Sure / Ultra-).
5. The least-preferable option is a generic protected Li-ion.
6. Unprotected rechargeable Li-ion cells should not be used.
7. Standard cells (non-rechargeable) should not be used
IMR batteries will not ruin this device, and are the least likely to explode on you. IMRs are not protected - they have a different, and actually safer chemistry.
