Next Gen 1S Super Charger Coming Up!

epilot@rcgroups notes a new lipo charging solution over at banggood. 10 pieces for less than $10!  I'm going to get a batch and try two things:

  • Next Gen Super Charger, even lighter weight than the old one.
  • Embedded Lipo Charging for the ArrMote.

notes:
  • resistor R3 determines the charge current.
  • 1.2Kohm on board, meaning the charge current is 1000mA.
  • Substitute R3 as per the Rprog table in the data sheet to reduce charge, e.g. 5Kohm = 250mA charge current.
  • lowest charge rate = 130 mAh
  • boards have an overcharge protection circuit.

Here's the TP4056 Data Sheet and the current table.

RPROG (k) IBAT (mA) 
10         130 
 5         250 
 4         300 
 3         400 
 2         580 
 1.66      690 
 1.5       780 
 1.33      900 
 1.2      1000
