Lithium Manganese Batteries

Well you know you get obsessed with power and all and you take notice when this sort of stuff pops up. My question is with the chart, Charge is rated at "77amphours" but "maximum power yield" is 120amphours:

THis is the web link, the chart reproduced below didn't quite transplant as the right format - http://www.torqeedo.com/en/hn/products/power/technical-data-measures.html


Technical data & measures (mm)
Torqeedo Power 26-77
General data

Capacity
2.0 kWh

Charge
77 Ah

Rated voltage
25.9 V

Final voltage
29.05 V

Weight
19 kg

Dimensions (length x width x height)
510 x 176 x 223 mm

Electrochemical base
Lithium manganese (LIMA)

High-current resistance

Maximum yield
3.1 kW

Maximum power consumption
120 A

Ladung

Charge characteristic
CC-CV (Constant Current - Constant Voltage)

Duration of charge using 350 W charger
< 6 hours

So what does this mean? Can you draw 77amhours out of it or 120amphours, not that I'd ever be able to afford one but know, we dream on don't we.

A 19kg battery that is good for 120amphours and charges like an AGM, I'd like that!

Unfortunately it suffers in the translation from German

"Maximum Power Comsumption" should read maximum load current - the unit is amps (A) - NOT amphours.

It clearly states that it's 77 amphours.

But it's a 24 volt battery - where would you use it ?

uh oh, thought it was 12v, sorry. Was looking into their claimed lighweight freshwater outboard electric motors and followed the links to their batteries ...
