Good choice for 100 watt ham radios in the field.
Style: 12V 20Ah-MS
They're many batteries to choose from. I choose this battery after a long study because of price and output power, in amps, ability. This battery will supply 20 amps with a surge of 30 amps. Most smaller size batteries cannot handle the current draw of a 100 watt radio transmitter but this battery has a 20 amp BMP will provide 20 amps plus the surge. This allows full output from an hf radio running at 200 watts sush as my FT891 and FT710. Wth a 20 total current storage it last for many hours and has a reasonable weight

These batteries will fail you when you need them to work.
Style: 12V 20Ah-MS-2 Pack
I have bought 4 of these. 1 of them have quit working I have only had them for around 7 months and have only used them a few times. These LifeP04 batteries should last a lot longer. I am extremely disappointed in this issue. So at this point in time I would definitely not recommend buying these batteries. Especially since they will fail you when you need them most like mine did. I am extremely disappointed in this product especially for the price they should work for a lot longer. I'm going to have to say they sold me a bad battery. I will not purchase anymore batteries from this company as they are obviously not a reliable battery. I design and build portable solar generators. I built 4 small portable units and this battery failed me. I can not have that issue because these are used in off grid activities.

Good replacement for lead acid
Style: 12V 20Ah-MS-2 Pack
Seems to last longer than the lead acid. From literature these are more stable than lith-ion. Will have to see what the life of the batteries are for longevity.
