Is it normal for LiFePO4 batteries to warm up while charging?
Positive cable hot and negative cool is suspicion, unless something like shunt is acting as a thermal break or heatsink. It may be that battery dissipates more power charging than discharging. Wires will be equal in either direction of current flow. BMS has MOSFETs with some resistance, and separate FETs for charging vs. discharging path.
Charge Battery: Where Do I Put The Negative Clamp?
To prevent that, and to give the battery a longer life, I''m told by a battery salesman I should charge it occasionally to keep up its condition. So I bought a charger and the manual states that the red clamp should go on the positive pole of the battery but the negative should be attached to the chassis of the car (ground/mass).
Charging batteries, do you connect negative to positive and
Parallel, positive with positive and negative with negative. 2 things connected with a wire will try to be at the same voltage/potential. If you connect 2 batteries with different charge states (let''s say 3.7V and 4.2V), if we assume negative as zero, in the positive pole, the 3.7 will try to rise and the 4.2 to decrease until they reach the same potential, this happens by moving charge from
