Does a li-po/li-ion battery that has a pcm and ntc thermistor need 3 wires?

However a 2 wire battery connected to a three wire charger should have the thermistor connection on the charger terminated, usually with 10Kohm, to ground. That simulates a three wire battery, and fools the charger into passing current by signalling the temperature is "normal". Without such a termination the charger will think the temperature

In a parallel connection, the positive terminals of both batteries are connected together, and the negative terminals are connected together.This results in a battery bank with the same voltage as a single battery, but with increased capacity.

4 Frequently Asked Questions about “Change three-wire battery to two-wire”

How do you wire two batteries in a series?

To wire two batteries in a series, attach one positive terminal to the other's negative, and then use the free positive and negative terminals to attach to your actual destination. I find that the little 9v battery clips are the easiest way to do them, although I could only find one of them when I did this project.

Is there a solution to the Timeless 2 wire 3 wire question?

A possible answer to the timeless 2 wire 3 wire question for tablet/GPS etc. Although not yet done by me as I had already done the direct connection of white to black but have kept old battery for later. My suggestion is transfer/change the old BMS to the new battery. If you try this please provide feedback for other users.

Can a 2 wire battery control a tablet charging controller?

(with the 2 wire battery I could trick the tablet charging controller to be always on by connecting the thermistor sensing wire to ground via fixed resistor. This will only be safe if the 2 wire battery is able to control the safe charging by itself hence my question). How are 2 wire batteries afe if they have no third wire?

Is it safe to use two wires on a battery?

Tablets and / or batteries only use two wires are indeed less safe (I wouldn't necessarily call it unsafe) than a three-wire system, if they don't compensate the missing thermal sensor in the battery (for example by an on-board thermal sensor, mounted near the battery).
